Nancy. Try a stiff grill brush, then spray with Easy Off. Rinse the grids with the hose, and put them back on the grill. Aloha!
Nancy,. I'd, sand the grill, then paint it with metal paint. Next, coat it with paint that can stand the elements. You could probably spray paint it, but that takes some preparation. I would also buy a grill cover.. Aloha!
Stiff brush, there are chemicals that will help, but the best way will be elbow grease. If you use steel or brass brushes...caution some of the bristles WILL fall out, #1 they in turn will cause rust, #2 YOU DO NOT WANT TO BITE DOWN ON A BRISTLE embedded in your food hurts
Should have said outside of the grill. Inside is clean and rust free.
Vinegar and baking soda.
You are most welcome Nancy! Give it a go, I know you can do this. 🌞
Here is a link to some rust removers on Amazon. Some of them are water based and non toxic.
Thank you for the links!
