Rust Removal from Cast Iron


I have had a COOK'KETTLE cast iron barbeque grill for 5 years. The last year, it has become completely rusted. I've used a wire brush in an attempt to clean it, but to no avail. Is there anything that will remove the rust from the cast iron?

We have products which can be used for this, but it is probably easier for you to go to the hardware store and buy a "de-rusting" product off the shelf. We are sure that the hardware store will help you with this. You need to know, of course, that it will re-rust again over time if exposed to normal moisture and air.

Good luck.

I use a Dremel to remove all the rust, then treat the iron with a very light amount of vegetable oil, put in a hot oven until the oil pools and starts to sizzle slightly, then submerge in cold water, dry with a clean rag.

Repeat process until the piece is blacken, the iron will not rust again if proper cleaning techniques are used, salt can be used to scour the iron with a damp cloth or rag, keep away from water, and humidity as much as possible.

Please never heat up cast iron and then submerge it in cold water- IT WILL CRACK- If you do it is pretty much toast- I have welded some small cracks or breaks but it is tricky.

The house we bought came complete with a wonderful smoker. Only trouble is the doors are rusting and need refinishing. My husband gave me naval jelly to remove rust after I am done scrubbing with a wire brush. My questions are: 1) Do I have to do more than remove the "loose" rust before painting, 2)If I do, is there any easier/quicker way to do the rust removal, and 3) What is the best paint to cover them with once I'm ready? Thanks!
