A viral image of cloudy rice water being poured from a pot into a bowl is making people rethink a common habit. The message printed across the photo is simple: “Don’t throw away rice water — it’s incredibly useful around the house.”

For many families, rice water is poured down the drain without a second thought. But in many Asian households, it has long been reused for everything from cooking to cleaning, and even hair care. While rice water is not a miracle solution, it can be a practical, low-cost way to reduce waste—if used safely.

What Is Rice Water, Exactly?

Rice water is the starchy liquid left behind after rinsing rice or boiling it. It becomes cloudy because rice releases starch into the water. Depending on the rice type and how long it’s rinsed or cooked, rice water may contain:

• starch and carbohydrates

• trace vitamins and minerals

• small amounts of protein

• mild cleansing properties

This is why many people describe it as “liquid gold”—not because it’s rare, but because it’s useful and usually wasted.

1) A Simple Cooking Trick That Reduces Waste

One of the most traditional uses of rice water is in the kitchen. Because it contains starch, it can subtly improve texture in certain recipes.

Common cooking uses include:

• Thickening soups and stews: Add a small amount to give a smoother consistency.

• Making porridge or congee richer: Rice water adds mild body and flavor.

• Soaking dried beans or lentils: Some cooks say it helps soften them faster.

• Preparing dough or batter: In some recipes, rice water helps create a softer texture.

These uses may vary by region, but the logic is the same: starch helps create smoothness.

2) Mild Cleaning for Kitchen Surfaces and Dishes

Rice water is sometimes used as a gentle cleaning aid. The starch can help lift grease and dust, especially for quick daily cleaning.

Household cleaning uses:

• wiping countertops and sink areas

• soaking oily dishes before washing

• cleaning glass when diluted (test first)

• polishing some kitchen tools

Important note: rice water is not a disinfectant, so it should not replace proper cleaning solutions in areas that come into contact with raw meat.

3) A Gentle Boost for Houseplants (When Used Correctly)

Some people reuse rice water for plants because it contains small nutrients that may support soil microorganisms. But experts warn: too much can cause problems.

Safe plant tips:

• Use unsalted rice water only

• Dilute it with clean water

• Use it occasionally, not daily

• Avoid letting it sit and ferment unless you know what you’re doing

If rice water smells sour or attracts insects, discard it.

4) The Viral Beauty Trend: Hair Rinse and Skin Toner

Rice water has become a popular beauty hack online, especially as a hair rinse. Some users claim it helps hair feel smoother, shinier, and easier to manage. Others apply it to skin like a gentle toner.

Why people use it:

• lightweight, easy to make

• can reduce frizz for some hair types

• gives a “clean” feel on skin

However, dermatologists often recommend patch testing first. Homemade mixtures can cause irritation, especially if stored improperly or used on sensitive skin.

5) The Most Important Rule: Store It Safely

Rice water can spoil quickly because starch feeds bacteria. If you plan to reuse it, handle it carefully.

Food-safety and hygiene tips:

• Use it the same day whenever possible

• Refrigerate immediately if storing

• Use within 24–48 hours

• Discard if it smells sour or changes texture

• Keep containers clean, especially for skincare use

Never keep rice water at room temperature for long periods.

What Experts Say: Helpful, But Don’t Overhype It

Rice water can be a useful household tool, but it is not a magical cure-all. It won’t replace cleaning chemicals, medical treatments, or professional skincare. Still, it can be a smart habit for families who want to reduce waste and save money.
