I clean kettles on my back lawn. I try to use environment friendly cleaning soaps as when I hose off the kettles, everything drips onto the lawn. Because of this I have been using Dawn concentrated soap and SOS pads. Both are non toxic and do not harm my lawn. I have used the Weber Grate Cleaner when cleaning the inside of gas grills. I spray it on, let it sit for 10 minutes, then power wash. When cleaning kettles, here is my normal routine:
- scrape inside of lid and bowl with a razor scraper
- scrub the inside and outside of the lid and bowl using Dawn soap and a SOS pad
- once dry, remove any carbonized residue left by using #0000 steel wool
