10 Surprising Uses for Citric Acid Around Your Home

Citric acid is more than just a tangy ingredient in citrus fruits—it’s a powerful, natural cleaner that’s gaining popularity in eco-conscious homes. From removing soap scum to polishing copper, this pantry staple has a wide range of household applications. Here’s how you can use citric acid for a cleaner, greener home.

1. Remove Soap Scum Naturally

Mix one part citric acid with two parts warm water in a spray bottle. Apply to problem areas, let sit for 15 minutes, then scrub and rinse. It’s perfect for bathrooms and kitchens.

2. Boost Laundry Power

Add a tablespoon of citric acid to your laundry to brighten whites, soften water, and eliminate odors. It’s especially useful in areas with hard water.

3. All-Purpose Cleaner

Combine one tablespoon of citric acid with one cup of warm water. Spray on counters, sinks, or tiles. Avoid natural stones like granite or marble.

4. Polish Stainless Steel and Copper

Use a paste of citric acid and water to clean copper cookware or polish stainless steel appliances. Rinse and dry thoroughly after scrubbing.

5. Eliminate Lime and Rust

For lime scale, pour a citric acid solution over the affected area and let it sit. For rust, apply a paste and scrub gently after 30 minutes.

6. Refresh Your Dishwasher

Sprinkle two tablespoons of citric acid in your empty dishwasher and run a hot cycle. This clears mineral buildup and odors naturally.

7. Streak-Free Window Cleaner

Mix a tablespoon of citric acid with a cup of warm water. Spray on windows and wipe with a lint-free cloth or squeegee for a crystal-clear finish.

8. Tackle Fabric Stains

Create a paste and apply it to fabric stains. Let sit for 15–30 minutes, then rinse or launder. Always test on a hidden area first.

9. Sparkling Bathrooms

Use citric acid to clean toilets, tiles, and grout. Spray or sprinkle, let sit, scrub, and rinse. It’s a chemical-free way to fight mildew and stains.

10. Deodorize and Dust

Use citric acid as a natural deodorizer and light dust repellent. Sprinkle on carpets, let sit, and vacuum for freshness.

Final Tip: Always test citric acid on a small area first. While it’s generally safe, it may react with certain materials like natural stone or delicate fabrics.
