Put 1 Bar of Soap in Boiling Water! I Have Stopped Wasting Money!

Lucy Evans

There are some simple household tricks that save you money, reduce waste, and make your daily life easier. This is one of those tricks. A single bar of soap, dissolved in boiling water, creates a versatile liquid soap that can be used for cleaning your hands, your dishes, your floors, and more.

Once you try it, you will understand why so many people have stopped buying expensive liquid soaps and cleaners.

Why this works so well

A standard bar of soap is made of fats and oils that have been saponified into a solid bar. When you dissolve it in hot water, the soap molecules disperse evenly throughout the liquid, creating a rich, soapy solution that works exactly the same way as liquid soap you buy at the store.

The result is a gentle, effective cleaning liquid that costs a fraction of what you pay for bottled soap.

The simple method

You will need:

  • 1 bar of plain, unscented soap (castile soap is best, but any mild bar works)
  • 4 cups of filtered water
  • A large pot
  • A wooden spoon
  • A glass jar or bottle for storage

How to make it:

  1. Grate the bar of soap using a cheese grater. The smaller the pieces, the faster they will dissolve.
  2. Bring the 4 cups of water to a gentle boil in a large pot.
  3. Add the grated soap slowly, stirring constantly.
  4. Reduce the heat and let the mixture simmer gently, stirring occasionally, until all the soap has dissolved. This takes about 5 to 10 minutes.
  5. Remove from heat and let the liquid cool completely.
  6. As it cools, it will thicken into a gel-like consistency.
  7. Pour the liquid soap into a clean jar or an old liquid soap dispenser.

How to use it

  • As hand soap. Pour it into a pump bottle and use it just like any liquid hand soap.
  • As dish soap. Use it to wash dishes by hand. It cuts through grease surprisingly well.
  • As a gentle floor cleaner. Add a few tablespoons to a bucket of warm water and mop as usual.
  • As a laundry pre-treatment. Rub a small amount into stains before washing.
  • As a general household cleaner. Dilute it with water in a spray bottle and use it on counters, sinks, and stovetops.

What people are noticing

Those who try this method often report:

  • A significant reduction in spending on cleaning and personal care products.
  • Less plastic waste from empty bottles.
  • A single bar of soap lasting much longer than expected.
  • A simple, natural soap that is gentle on their skin.

A gentle word of caution

  • Use a plain, unscented soap if you have sensitive skin. Avoid heavily perfumed or moisturizing bars, as they may leave residue.
  • The soap will thicken as it cools. If it becomes too thick to pour, add a little warm water and shake well.
  • Store the soap in a clean container. Use it within a few months.
  • If you are using it for dishes, rinse your dishes thoroughly with clean water.
  • If you have hard water, the soap may leave a slight film on dishes. Adding a splash of white vinegar to your rinse water helps.

Why you will never waste soap again

You have probably let small slivers of soap go to waste at the bottom of your soap dish. Now you know better. A bar of soap, a pot of boiling water, and a few minutes of your time are all you need to create a versatile, money-saving liquid soap that works for your hands, your dishes, and your home.

Try it once. You will wonder why you did not start sooner.
