How do you get rid of the Rust on an iron muffin/cupcake pan?

Step 1. Fill your sink with a solution of 1 part white vinegar to 1 part water. Immerse your cast-iron pot in the solution.

Step 2. Allow the pot to soak for up to 4 hours. Do not over-soak.

Step 3. Remove the pot from the solution and rinse. With a nylon scrub brush, scrub the pot in a circular motion to remove any loose rust that remains. Dry with a towel.

Step 4. Inspect the pot for signs of rust and lightly sandpaper any traces of it.

Step 5 Heat your oven to 350 degrees F. Lightly coat your entire pot with vegetable oil or shortening. Place a cookie sheet lined with foil on the bottom rack of your oven. Place the pot upside down on the middle rack and leave it in the oven for 45 minutes. Remove, let cool, and store.

Depends on how bad the rust is on the item. My grandmother would take a piece of wax paper and cooking oil and scrub the pan until the rust would come off. Then she would on warm oven bake the pan grease lightly with oil. She would take the pan out and again grease it with oil again and put a paper towel on it and place it on the shelf or wherever. This has worked for me when my daughter or husband accidentally left water in the pan.

Cast Iron Muffin

Oven 'self-clean' won't take care of rust. If you plan to use them for baking, scour them good with soapy water and a copper scrubby. Dry them thoroughly and smear the with a coat of cooking oil. Then bake them in the oven for awhile then repeat. Always oil them before using and use a non-stick spray. They should eventually turn a uniform black called "seasoning". If you only plan to use them for decorative purposes, buy a product at the Hardware Store called "Navel Gelly". This stuff will dissolve the rust. Follow the directions on the bottle, dry and spray with a coat of varnish or Rustoleum Brand paint.

Clean them with baking soda and a scrubby then wash and put them in the oven to dry on low temperature also oil the inside to prevent them from rusting do the same with iron frying pans

Kayboff beat me to it ... but she's got it down pat step by step. Always avoid using soap on cast iron after it has been seasoned the first time. To prevent rusting, dry all cast iron either in the oven or on the stove top immediately after washing (note, when cleaning cast iron after cooking you actually just use hot water and wipe/scour as needed. Soap breaks down the seasoning which causes the iron to breakdown with the humidity, etc.)

Have you tried a soapy Brillo Pad? I never let water stand in my iron skillet. Always wash your pans and dry them right after each use. If the rust won't come out toss it. Poppy

Steel wool will get that rust off next time you wash them in hot, soapy water. Just make sure they are thoroughly dry before you put them away. You can either heat them on the stove burner or put them in a warm over until they're dry.

Clean off the rust with a S.O.S pad and then dry it, and then bake it for an hour after coating it with some cooking oil.

cooking oil will take it off, its no biggy, just pour some on a paper towel and wipe if off the pans, wash really well with warm soapy water and then coat them very lightly with cooking oil !! I've done this and it works
