emoving rust stains from clothing and fabric. There are three things you can try to remove rust stains from clothing or other fabrics. The first is a combination of lemon juice and salt. Lay your clothing out flat, and pile salt over the stain. Then, pour some lemon juice onto the salt until it’s saturated. Let that sit for 30 minutes before you rinse it. Some people leave it out in the sun for 30 minutes, but be careful because citric acid can bleach fabric. The second thing you can try is plain white vinegar. Soak the stain in vinegar for a few minutes, then rinse it with water. Third, since chlorine bleach will set a rust stain, try a little hydrogen peroxide and cream of tartar. Make a paste, and spread it over the rust stain. This one can only be used with rust stains on white clothing. Whatever you do, don’t put anything in the dryer until you have removed the rust stain; drying might set it.
