How to Use Citric Acid for Cleaning
General spray solution
- 1 tablespoon citric acid powder
- 1 cup warm water
Spray, let sit 5–10 minutes, scrub, then rinse.
Heavy limescale
- Sprinkle powder directly on the damp surface
- Let it sit briefly
- Scrub gently and rinse
Descaling appliances
- Dissolve 1–2 tablespoons in warm water
- Run a short cycle (always rinse after)
Advantages of Citric Acid
- Very effective on hard water stains
- Odorless compared to vinegar

- Affordable and easy to store
- Less harsh than many commercial cleaners
Important Warnings (Where Not to Use It)
Citric acid is acidic and can damage certain materials.
Avoid using it on:
- Natural stone (marble, granite, limestone)
- Unsealed grout
- Aluminum (can corrode)
- Enamel if left too long
Always test on a small hidden area first.
Citric Acid vs Vinegar
- Citric acid: stronger on limescale, no smell, powder form
- Vinegar: easier to find, weaker, strong odor
For heavy mineral buildup, citric acid usually works better.
Bottom Line
Citric acid powder is excellent for cleaning, especially for limescale, hard water stains, and descaling appliances. Used correctly, it’s a powerful, natural, and inexpensive cleaner. Just avoid sensitive surfaces and don’t let it sit too long.
