The Hidden Power of Rice Water: A Natural Cleaning Hack That Works

What if I told you that the leftover water from rinsing your rice could be the secret weapon to a cleaner, more eco-friendly home? For generations, rice water has been praised in various cultures not just for hair or skin care, but also as a natural, zero-waste cleaning agent. Today, I’ll share how I tested rice water in my kitchen and laundry room—and the surprising results.

What Is Rice Water?

Rice water is the starchy liquid left behind after rinsing or boiling rice. Rich in nutrients like starch, trace minerals, and antioxidants, this water isn't just waste. In fact, its slight acidity and cleansing properties can make it a powerful (and safe) household helper.

There are two types:

• Rinse water – when you wash raw rice

• Boiled rice water – thicker, used sparingly

Why Use Rice Water for Cleaning?

Before diving into my experience, here’s why rice water deserves a spot in your cleaning kit:

• Completely natural – no harsh chemicals

• Zero-waste – reuse something you’d normally throw away

• Safe for sensitive surfaces – ideal for natural stone, wood, or even plants

• Slightly acidic – helps cut through mild grime

1. Kitchen Counter Test: Can Rice Water Cut Grease?

The Setup:
I tried using rice rinse water on my kitchen countertop, which had slight oil residue from meal prep. I poured the water into a spray bottle and added a few drops of lemon juice.

Method:

1. Spray on surface

2. Let sit for 1–2 minutes

3. Wipe with microfiber cloth

Result:
Shockingly effective. The mild starch seemed to “grab” the oil without leaving streaks. I noticed the counter was slightly shinier than usual possibly from the starch residue.

Verdict: 8/10
For light grease and daily wipes, this worked very well. For heavier buildup, I still needed soap.

2. Glass and Mirror Cleaning

Method:
Same solution, this time without lemon. I wiped my bathroom mirror with it using a dry microfiber cloth.

Result:
At first, it left streaks, but when I diluted the rice water 1:2 with clean water, the result was much better—comparable to a mild glass cleaner.

Verdict: 6.5/10
Use diluted, and avoid boiled rice water (too thick). It’s not perfect, but works in a pinch.

3. Laundry Booster for Whites

Here’s the surprise: rice water can act as a mild starch for fabrics.

Method:
I added 1 cup of boiled rice water (cooled) to the final rinse cycle of my white cotton dish towels.

Result:
They came out a little stiffer, but noticeably brighter. The light starch gave them a crisp, fresh feel. I wouldn’t use it every wash, but once in a while—perfect.

Verdict: 7.5/10
Great for towels or linens that need a light refresh.

4. Floor Cleaning with Rice Water

Method:
I added 2 cups of rice rinse water to a bucket of warm water, with a few drops of eucalyptus oil. I used it to mop my wooden floor.

Result:
It cleaned well and left no residue. The slight acidity lifted dust and gave a faint sheen. Plus, it didn’t dry out the wood like vinegar sometimes does.

Verdict: 9/10
Perfect for wood or laminate floors. Eco-friendly and gentle.

Tips for Best Use

• Use fresh rice water – don’t let it ferment too long or it’ll smell sour.

• Always strain particles before using.

• Do not store longer than 1–2 days unless refrigerated.

• Use it on test spots first, especially on delicate fabrics or surfaces.

When NOT to Use It

Avoid using rice water on:

• Heavy grease (use dish soap)

• Mirrors without dilution

• Surfaces prone to mold (fermented rice water may feed it)

Final Thoughts

Rice water may seem like just a byproduct but it’s actually a powerful, natural helper that deserves more attention. From cleaning counters to refreshing laundry, this simple liquid offers a safe, cost-effective alternative to store-bought cleaners.

As someone who prefers eco-friendly living without sacrificing results, I’m convinced: rice water is a hidden gem worth trying in your home routine.
