Is it removable? If so, removee and clean it well with soapywater and a scrub brush, let dry, then spray it with heat/fire-resistant paint. If you need to paint it in place, do the same but be sure to mask off all thesurrounding areas very well. It is difficult to contain paint spray!

You will need high-temperature stove paint. Here's a link:

I agree removing it would be the easiest way to paint as I believe most high heat paints only come as spray paint. However, they might make a brush on kind, I would check online with a google search!

Hi! I would take it outside, clean it really well, and then spray it with a high temperature paint. It's what I have always done with rusty grills and fire pits. I believe the one we've used is by Rustoleum. Do light coats and let dry in between. Good luck!
