Rust stains appear on the inside and outside of coffee pots because of leftover coffee or water sitting on the pot for a long period of time. Conventional dish cleaning products remove coffee stains and bad odors from a coffee pot, but these cleaners may not work in tackling tough rust stains. Two common kitchen products, when combined, create a rust cleaner that takes away such stains from a coffee pot without causing any damage to the pot.
Things You'll Need
Rinse the rust-covered area of the coffee pot with tap water.
Sprinkle about 1 tbsp. of table salt over the area of the pot covered in rust. Use more salt, if necessary, to cover all of the rust.
Cut one to two whole limes in half. Then, squeeze the juice from the lime(s) onto the salt-covered portion of the coffee pot. Do so until no more juice comes from the lime.
Leave the salt and lime juice onto the coffee pot for approximately two to three hours.
Scrub the coffee pot either with the leftover part of the lime or a moistened sponge/cloth. Rinse the coffee pot with lukewarm tap water. Inspect the coffee pot, and repeat the process if you still notice rust on the coffee pot.
