I only use the Easy off brand, i tried the Dollar oven cleaner. its weak at best.
I decide which is better based ont he gunk of the grill.
Sometimes the oven cleaner is not gonna cut it, no matter what.
Razor blades are way cheaper. I can scrape an average bowl and lid pretty fast.
i also use the Dollar store SOS pads. Way cheaper than true 0000 steel wool.
I reseve that for straight polishing of the exterior.
For grates and OT parts, i use my $10 harbor freight grinder with a wire wheel attachment.
Thats does amazing work in a short time..
At some point I plan to get a small buffer to do the gold bowls and possibly the legs.
OK, are we still talking about Kettles? Lol!
