Put 1 BAR OF SOAP in boiling water and stop spending money at the store

Sofia Rossi

There is a simple, old-fashioned trick that can save you money on cleaning products and reduce the number of bottles cluttering your cabinets. It requires just a single bar of plain soap and some boiling water. The result is a versatile, gentle cleaner that can be used for many household tasks.

Why This Works

A simple bar of soap, such as castile soap or a basic glycerin soap, is a concentrated, gentle cleanser. When dissolved in hot water, it creates a liquid soap that can be used for cleaning floors, countertops, dishes, and more. It is free from the harsh chemicals, synthetic fragrances, and preservatives found in many commercial cleaners.

The Simple Method

What You Will Need

  • 1 bar of plain, unscented soap (castile soap or glycerin soap works well)
  • 4 cups of boiling water
  • A large pot or heatproof container
  • A grater

How to Prepare

Step 1: Grate the entire bar of soap using a standard kitchen grater. The finer the shreds, the faster they will dissolve.

Step 2: Bring 4 cups of water to a rolling boil in a large pot.

Step 3: Remove the pot from the heat and add the grated soap. Stir gently until the soap is completely dissolved.

Step 4: Let the mixture cool completely. It will thicken as it cools.

Step 5: Pour the cooled liquid soap into a clean, labeled container or an old soap dispenser.

How to Use It

All-Purpose Cleaner – Dilute the liquid soap with water in a spray bottle (about 1 part soap to 3 parts water). Use it to clean countertops, sinks, stovetops, and other surfaces.

Floor Cleaner – Add a small amount of the liquid soap to a bucket of warm water for mopping floors.

Dish Soap – Use the liquid soap directly on a sponge for washing dishes.

A Kind Reminder

This cleaner is gentle and effective for most surfaces. Test it on a small, inconspicuous area before using it on delicate surfaces. A simple bar of soap, dissolved in boiling water, can become a versatile, cost-effective cleaner that replaces many bottles under your sink.
