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.
Step 1
Rinse the rust-covered area of the coffee pot with tap water.

Step 2
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.
Step 3
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.
Step 4
Leave the salt and lime juice onto the coffee pot for approximately two to three hours.
Step 5
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.
