Similar to rust stains on fabrics, rust stains on your skin are hard to get rid of. Iron corrodes when exposed to water or air moisture, and a rusty, red and orange surface emerges. When touching this surface, you may end up with unexpected stains on your skin. There are many commercial products that remove rust stains from material surfaces, but the chemicals in these may irritate your skin. However, you can use a mixture of lemon juice and salt to remove rust stains from your skin.
Place 2 tablespoons of salt in a bowl.
Juice a lemon. Pour the lemon juice in the bowl, and mix it with the salt. Use just enough lemon juice to get a paste-like consistency. You can also use vinegar, as an alternative.
Apply the mixture to the rust stain on your skin. Massage the area with your fingertips for three minutes. Add light pressure to thoroughly scrub the skin. The salt exfoliates the skin, removing the dead surface layer, while the lemon juice's citric acid removes the rust stain. Acetic acid in vinegar has a similar affect as the lemon juice.
Rinse the salt mixture from your hands with warm water, and dry your hands with a towel. If the stain persists, repeat the process.
