Rice water and toothpaste: An unexpected duo for household cleaning
It may seem unusual, but combining rice water and toothpaste can be surprisingly effective for household cleaning. Rice water contains a small amount of starch, protein, and mild alkaline enzymes that help soften dirt and grease, while toothpaste has mild whitening agents, soft abrasives, and deodorizing flavors.

1. Cut through grease on stoves and countertops
Grease can be a stubborn stain on gas stoves, electric stoves, walls, and range hoods. However, a mixture of rice water and a small amount of toothpaste can be a powerful solution. Pour the mixture into a spray bottle, wait for a few minutes, and then wipe it away with a soft cloth or sponge. The starch in the rice water softens the grease, while the mild abrasive in the toothpaste breaks down the stain without scratching the surface.
2. Remove rust stains
Over time, kitchen utensils like pots, knives, and screwdrivers may develop rust. Soak them in a basin of rice water for about 10 minutes, and the mild acidity of the rice water will react with the rust, causing it to loosen without any scrubbing. For tougher rust stains, apply some toothpaste directly onto the affected area and gently scrub with a soft brush. Rinse with clean water, and your metal items will look as good as new!
3. Clean floors
Rice water is mildly alkaline and can effectively remove dirt, grease, and stubborn stains without damaging floors, including wooden and stone surfaces. It also leaves a natural starch coating that helps protect against scratches and adds a subtle shine. Adding a small amount of toothpaste to your floor cleaning solution will boost its stain-removing power, even for tough stains like shoe marks, coffee spills, or grease, while still being safe for your hands and the floor itself.
4. Get rid of yellow stains in the toilet bowl
Toilet bowls can develop unsightly yellow stains due to hard water, bacteria, and grime build-up. Instead of using harsh chemicals, try a mixture of rice water and toothpaste. Pour it directly into the bowl, let it sit for a few minutes, and then scrub gently with a toilet brush. The yellow stains will fade away, and the fresh scent of the toothpaste will help neutralize any unpleasant odors.
5. Eliminate paint odors from furniture or wooden doors
Fresh paint can leave a strong and lingering odor that may be unpleasant and even harmful if inhaled for extended periods. Rice water contains natural compounds like alkaloids and starch, which absorb chemical odors. Toothpaste enhances this effect and leaves a pleasant fragrance. Using a clean cloth, wipe down newly painted wooden surfaces or doors with a mixture of rice water and toothpaste. Repeat this process daily for 2-3 days, and you’ll notice a significant improvement in the air quality without needing to resort to air purifiers or chemical air fresheners.
Additionally, this mixture can be used regularly to clean and polish wooden furniture, preventing dust build-up and maintaining a shiny appearance while also eliminating any musty odors.
