I Haven’t Bought Dish Soap in 35 Years, The $1 Trick That Works Better Anyway

Buying another bottle of dish soap can feel harmless until you notice how quickly it disappears. You squeeze a little more for greasy pans, add another squirt when the bubbles fade, and soon another plastic bottle is back on the shopping list.

That was exactly what bothered Betty. In 1985, her mother in law showed her a cheaper way built around plain Castile soap, careful washing habits, and using the right cleaner for the right mess.

Betty kept the routine for decades. Some parts still work beautifully today, while a few old kitchen rules need modern safety updates.

Betty’s Homemade Dish Soap Starts With One Simple Jar

Betty’s whole routine begins with a simple idea: everyday dishes do not always need a brightly colored bottle of liquid sitting under the sink. For ordinary hand washing, a small amount of plain soap can often do the basic job.

Her mother in law used Castile soap, which is a true soap traditionally made from vegetable oils. Betty learned to turn a bar into a soft concentrate that could sit beside the sink in a reusable jar.

She grates a small amount of plain Castile bar soap and dissolves it slowly in hot water. Once the mixture cools, it becomes thicker and can be spooned into the wash basin as needed.

The texture will not always match bottled dish liquid. Depending on the soap and your water, it may become a soft gel, a loose jelly, or a thinner liquid.

That is why Betty recommends starting small. There is little reason to make a year’s supply before knowing how the mixture behaves in your kitchen.

The old “$1 trick” comes from the days when a basic bar of soap could be bought very cheaply. A bar may cost more today, so the real lesson is not that every batch will literally cost one dollar in 2026.

The lesson is that a simple concentrate can stretch much farther when you stop pouring cleaner without measuring it.

Betty also keeps washing soda nearby for tougher jobs. Washing soda is sodium carbonate, and it is different from baking soda.

Its higher alkalinity can help loosen greasy soil and can improve cleaning in some hard water conditions. A small amount is usually enough, and gloves are useful if it bothers your skin.

Betty keeps near the sink	Main purpose	Important limit
Plain Castile soap	Everyday hand washing	Can leave film in hard water
Washing soda	Greasy pans and some hard water	Can irritate skin
Baking soda	Mild scrubbing	May scratch delicate surfaces
Dish scraper	Removes food before washing	Wash it regularly
Drying rack	Air dries clean dishes	Keep the rack clean

There is also one old rule Betty has softened with time. Her mother in law believed soap should never touch cast iron.

Modern cast iron makers such as Lodge say a small amount of mild dish soap is fine on a properly seasoned skillet. The more important habits are avoiding long soaking, drying the pan quickly, and adding a thin coat of oil when needed.

Betty still often cleans her cast iron with hot water and a scraper because that is usually enough. She simply no longer treats one drop of mild soap as a disaster.

She also washes dishes in a deliberate order. Glasses and cups go first, followed by plates, flatware, bowls, and finally greasy pots and pans.

Starting with the roasting pan would cloud the water immediately. Starting with the cleanest items lets one basin stay useful longer.

Handle Grease Before You Add More Soap

One of Betty’s biggest money saving habits happens before the soap ever touches the dish.

She does not expect detergent to do every job by itself. She removes what she can first, then washes what remains.

A pan with dried food often needs time more than it needs another squirt of cleaner. Betty fills it with warm water and lets it sit while she does something else.

An hour of soaking can soften food that would otherwise take several minutes of hard scrubbing. For suitable cookware, a little washing soda can help loosen a stubborn greasy layer.

Burnt pans get similar treatment. Betty adds water to sturdy cookware and gently heats it to soften cooked on residue before she starts scraping.

A small amount of baking soda can sometimes help with stubborn marks. However, cookware materials differ, so nonstick pans, aluminum, enamel, and specialty finishes should always be cleaned according to their care instructions.

Cutting boards require more caution than Betty’s older method suggested.

Her mother in law rubbed wooden boards with lemon and coarse salt. That can help loosen residue and reduce some odors, but it should not replace proper washing.

The USDA recommends washing cutting boards with hot, soapy water after use, then rinsing and allowing them to dry. This is especially important after preparing raw meat, poultry, seafood, or eggs.

Betty still uses lemon occasionally for smells, but only after the board has been properly cleaned.

Cloudy glasses are another place where she looks at technique before adding more cleaner. Too much soap can make rinsing harder and may leave a slippery or hazy finish.

Betty starts with less soap and gives drinking glasses a clean rinse. If mineral deposits from hard water are causing haze, white vinegar can sometimes help remove that buildup separately.

Her washing tool matters too. Betty prefers a dish brush that can be rinsed thoroughly and left standing where air reaches it.

A sponge can also work, but it should not remain wet and packed with food residue for days. Whatever touches clean dishes needs regular cleaning and a chance to dry.

Kitchen mess	Betty tries first	Why it helps
Loose food	Scrape it away	Keeps solids out of wash water
Fresh grease	Wipe off excess	Reduces oil in the sink
Dried food	Soak it	Softens residue before scrubbing
Burnt food	Warm or simmer water if safe	Loosens stuck material
Cloudy glass	Use less soap and rinse well	Reduces leftover cleaner

The basic rule is simple. Do not ask soap to remove something that a scraper, towel, or thirty minutes of soaking could remove first.

These Old Dishwashing Habits Cut Water and Cleaner Waste

Betty’s routine is cheaper partly because she treats water and cleaner as resources rather than something that can run endlessly.

She fills a basin instead of leaving the tap running through the whole load. Then she keeps the cleanest dishes at the front of the washing order so the water lasts longer.

She also removes visible grease before washing. A greasy skillet does not need to carry a layer of oil into the sink if most of that oil can be wiped away first.

Cornstarch was one of her mother in law’s tricks for loose grease. A small amount can absorb oil before the pan is wiped, although a scraper or paper towel is often simpler.

What matters is the order. Wipe first, wash second.

Betty also stopped believing that painfully hot water must be better.

Warm water helps soften grease and makes hand washing comfortable, but water does not need to be hot enough to redden your hands. Soap, physical scrubbing, contact time, and proper rinsing all matter.

For food preparation surfaces and utensils, follow modern food safety guidance rather than relying on touch alone. Hot, soapy water is still recommended for many kitchen cleaning tasks.

After washing, Betty rarely reaches for a dish towel. She stands dishes upright in a rack and lets the air finish the job.

That removes one repeated chore and keeps a damp cloth from touching every clean plate. If you prefer towel drying, use a clean towel and change it often.

Her mother in law also reused household wash water outside, but this is one habit that needs caution today.

Water containing grease, food residue, bleach, harsh cleaners, or a high level of sodium should not simply be thrown onto vegetable beds. Even mild greywater can cause problems if it is repeatedly used in the same soil.

Local rules also differ. If you want to reuse household greywater, check local guidance first and keep it away from edible plant parts.

The useful idea is conservation. The old rule of “every drop goes somewhere useful” can still inspire better habits without assuming every basin of dirty water belongs in the garden.

Why Thick Dish Soap Does Not Always Mean Better Cleaning

Betty remembers one sentence from her mother in law better than almost anything else.

The older woman looked at the bright bottle beside the sink and told Betty she was paying for things that made the product look and feel appealing, not just for the part that cleaned.

The wording was dramatic, but the basic point has some truth behind it.

Modern hand dish detergents contain surfactants, which help water loosen and carry away grease and soil. They may also contain ingredients that adjust thickness, fragrance, color, preservation, or performance.

A thick texture by itself does not prove that one cleaner cuts more grease than a thinner formula.

Some formulas use sodium chloride as a viscosity modifier. That means salt can be used to help control how thick a liquid feels.

Betty’s mistake would be claiming that thickness is always useless. It can improve pouring, dosing, stability, or the user experience.

The better lesson is that thickness should not be confused with cleaning power.

She learned the same thing with foam. A sink full of bubbles feels active, but extra bubbles are not a reliable measure of how clean a plate will become.

Betty starts with a small amount of her soap concentrate and adds more only if the water is clearly too greasy for the load.

There is no perfect teaspoon that applies to every commercial cleaner or homemade mixture. Concentrations vary too much.

For store bought detergents, follow the product instructions. For homemade soap, start conservatively and adjust based on how well it cleans and rinses in your water.

Baking soda is another example of choosing the cleaner for the problem.

When a mug develops a brown tea or coffee stain, more dish soap may not be the easiest answer. Betty puts a small amount of baking soda on a damp cloth and gently rubs the stained area.

That mild abrasion can lift marks quickly from durable surfaces.

Decorated mugs and delicate finishes may scratch, so test gently rather than treating baking soda as safe for everything.

Keep Food and Cooking Grease Out of the Sink

Betty thinks some of the best dishwashing advice has nothing to do with soap at all.

A sink becomes much easier to clean when most of dinner never enters it.

She scrapes plates before they reach the wash basin. Bones, vegetable scraps, rice, bread, thick sauces, and other leftovers are removed first.

Compostable scraps can go into a compost system where local rules and your setup allow it. The rest can go into the appropriate waste container.

This keeps solid food out of the wash water and gives the dish brush less work to do.

It also means Betty can often wash several dishes before the water starts to look dirty.

Cooking grease gets similar treatment.

Her mother in law kept a traditional grease jar near the stove and reused some rendered fat in cooking. Betty does not treat that as a requirement because food storage habits and health preferences vary.

What she does keep is the rule about the drain.

Large amounts of cooking grease should not be poured down the sink. Fats can cool and harden inside plumbing, especially when they mix with other debris.

Betty lets unwanted grease cool and disposes of it according to local waste rules. She may also wipe a greasy pan before it enters the wash water.

This simple habit can make a surprising difference.

Instead of asking the soap to break through a visible pool of oil, you are asking it to remove only the thin film that remains.

That means cleaner water, less grease on your washing tool, and less oil traveling into the drain.

Betty Uses a Few Cleaners Instead of a Bottle for Every Job

Betty’s kitchen does not have a separate spray bottle for every surface. She prefers a small group of basic products, but she also knows that one homemade cleaner cannot safely clean everything.

White vinegar is a good example.

Diluted vinegar can help with some mineral deposits and everyday grime. Betty sometimes uses it on surfaces that tolerate acid well.

But she never uses vinegar as a universal countertop cleaner.

Natural stone such as marble and limestone can be damaged by acid. Some granite surfaces may also be affected depending on the finish and sealant.

For stone, Betty uses a cleaner approved for the surface or a mild soap and water solution when the manufacturer recommends it.

She also does not treat vinegar as a registered disinfectant.

There is a difference between making a counter look clean and using an appropriate disinfectant when germs are the concern. This matters especially after raw meat or poultry preparation.

And vinegar should never be mixed with chlorine bleach.

Betty’s old habit of reusing rinse water for floors also gets a modern update.

If a basin contains clean looking water with very little soap and no raw meat residue, grease, harsh chemical, or food waste, it may sometimes be useful for another suitable cleaning job.

But flooring materials matter.

Wood, laminate, natural stone, vinyl, and tile all have different moisture and cleaner requirements. Betty checks the care instructions before treating leftover rinse water as free floor cleaner.

The easiest part of this section requires no chemistry at all.

She keeps the things she uses most within arm’s reach.

The soap jar stays beside the sink. The scraper is nearby. The brush can dry in the open. The drying rack is already set up.

Betty believes a frugal habit fails when it becomes inconvenient on a tired Tuesday night.

A simple tray beside the sink solves that problem. It keeps the routine visible without making the counter feel messy.

Turn the Cheap Dishwashing Trick Into a Routine That Lasts

Betty’s method works because it became boring.

There is no elaborate mixing day every week and no shelf filled with twenty homemade cleaners. Her routine uses a few basic supplies and repeats the same steps.

The first step is keeping the cleaning tools themselves clean.

A dish brush can collect grease. A drying rack can develop residue. A scraper can hold food around its edges, and the soap jar can become sticky around the lid.

Betty washes these items regularly and lets them dry thoroughly.

Her mother in law sometimes boiled cleaning tools, but Betty no longer recommends boiling everything automatically. High heat can damage some plastics, adhesives, wooden pieces, finishes, and modern materials.

Manufacturer instructions come first.

She also makes smaller batches of homemade soap than the giant yearly supply described in her old family story.

That old method made sense when someone already knew exactly how a particular bar soap behaved. For a beginner, a small batch is much safer and easier.

Homemade soap can separate. It can become very thick. It can remain watery.

Hard water can also make a formula that worked perfectly in one house perform poorly in another.

A small jar lets you test before committing.

The difference between soap and detergent also explains why results vary.

Traditional soap is created when fats or oils react with an alkali. Modern dish detergents usually use synthetic or plant derived surfactants designed to clean efficiently across a range of conditions.

True soap can react with minerals such as calcium and magnesium in hard water. That reaction may leave a cloudy film or soap scum.

Washing soda can sometimes help by changing the water conditions, but it does not solve every problem.

If your homemade Castile mixture leaves glasses dull after repeated tests, switching back to a good commercial hand dish detergent is perfectly reasonable.

Betty’s goal is saving money and simplifying the kitchen. It is not winning an argument with a bottle.

If this happens	Likely issue	What to try
Glasses look cloudy	Hard water or too much soap	Use less soap and rinse well
Soap jelly becomes very thick	Soap and water ratio	Dilute a small portion
Grease remains on pans	Too little cleaning action	Wipe grease first or use a suitable detergent
Hands feel dry	Formula too alkaline or irritating	Wear gloves or switch cleaners
Residue remains after rinsing	Soap and minerals reacting	Test a commercial detergent

The Real Trick Is Using Less and Cleaning Smarter

Betty’s strongest lesson is not that everyone should swear off commercial dish soap forever.

It is that you should know why you are reaching for a cleaner before you pour it.

A breakfast plate may need a scrape, a little soap, a quick wash, and a clean rinse. A roasting pan may need thirty minutes of soaking before it needs any scrubbing at all.

A stained mug may respond better to a pinch of baking soda than another large squeeze of detergent. A skillet coated with grease may become easier to clean after most of the oil is wiped away.

Different messes need different answers.

There are also times when modern dish detergent is simply the better choice.

If your water is very hard, true Castile soap may leave film. If you regularly wash heavily greasy cookware, a commercial detergent may cut through it more easily.

If you have sensitive skin, an appropriately formulated fragrance free product may also be a better fit than experimenting with homemade alkaline mixtures.

And Betty has one rule she never bends: homemade Castile soap jelly belongs at the hand washing sink, not inside an automatic dishwasher.

Automatic dishwashers require low sudsing detergent designed for the machine. Hand soap can create excessive foam and lead to a very unpleasant kitchen cleanup.

Food safety also comes before nostalgia.

Anything that has touched raw meat, poultry, seafood, or eggs should be cleaned according to current food safety guidance. Old household shortcuts should never replace proper cleaning and sanitizing when contamination is a concern.

That does not make Betty’s old system useless. It makes it smarter.

The best parts were never really about refusing modern products.

They were about scraping before washing, soaking before scrubbing, keeping grease out of the drain, measuring cleaner instead of pouring blindly, keeping tools dry and clean, and choosing the right method for each surface.

Those habits cost almost nothing.

They also explain why Betty stopped seeing the dish soap bottle as the center of the kitchen sink.

For her, the real cleaner was the system.

A small jar of homemade dish soap may become part of that system in your kitchen, or it may simply teach you to use less of the detergent you already own.

Either result can save waste.

Start with one small batch, one clean brush, and one sink of dishes. Keep the habits that make the work easier, and leave behind the ones that do not fit your home.

That is the part of Betty’s old kitchen lesson that still makes sense decades later.
