Citric acid is a natural preservative and antioxidant found in many industries, such as cosmetics, food, and pharmaceuticals. This organic acid is present in a wide variety of fruits, especially citrus fruits, although most commercial citric acid is obtained through sugar fermentation.
Widely used as a food preservative, citric acid is also a powerful ally for household cleaning, and can be used in many different ways.
Here are some of the main and most important uses of citric acid in the home:
1. Remove Rust
Prepare a solution of half a liter of water and two tablespoons of citric acid, pour it into a spray bottle, and shake well.
Spray the solution on the rusty object you want to restore, then scrub it with a small brush and dry it off. The item will look like new again. Remember not to use this on aluminum objects.
