If you’re looking for natural ways to clean your home, traditional Asian practices—especially in China, Japan, and Korea—suggest that rice soaking water is a surprisingly effective, free, and environmentally friendly cleaning solution. Instead of throwing it away, rice water can be reused in several household tasks.
Benefits of Using Rice Water for Cleaning
Rice soaking water contains natural starch, which helps bind with dirt, break it down, and prevent particles from sticking together. For this reason, it has been used in some Asian households for cleaning dishes and removing light odors.
In Korea, for example, washing dishes with rice water is a common traditional practice, especially since many Korean dishes are not heavily greasy. Some commercial dishwashing products even incorporate rice water as an ingredient.
However, experts note that rice water has limitations:
It is not effective for removing grease on its own.
Its slightly acidic nature (around pH 6) makes it unsuitable for breaking down oils, unlike alkaline dish soaps.
When mixed with strong detergents, it may reduce their effectiveness.
On the other hand, rice water works well for:
Removing light mineral deposits (like limescale or water stains)
Cleaning rust stains (light level)
Polishing surfaces usually treated with vinegar or lemon
⚠️ It should not be used on sensitive surfaces such as untreated stone or gypsum, which may be damaged by acidity.
Cleaning Uses Around the Home
Rice water is considered a multi-purpose natural cleaner. It can be used for:
Cleaning mirrors and windows
Mopping floors
Refreshing bathroom and kitchen tiles
Restoring shine to grout lines
After cleaning glass surfaces, it is recommended to wipe them again with a dry cloth to avoid white streaks after drying.
Removing Odors from Containers
Rice water can help eliminate unpleasant smells from plastic food containers:
Fill the container with rice water
Leave it for about 30 minutes or more
Rinse thoroughly afterward
Natural Fertilizer
If not used for cleaning, rice water can also be reused as a natural fertilizer for plants, thanks to its nutrient content.
How to Prepare Rice Water for Cleaning
Soak 1 cup of raw rice in 2 cups of water
Stir the rice until the water becomes milky
Strain the rice and collect the liquid
Dip a clean cloth into the rice water and use it for cleaning surfaces
If you have extra rice water, you can store it in a sealed container in the refrigerator for up to 5 days.
