Serious question, how do you deal with slag sticking to the furnace wall?

I always scraped it off cold, which was a chore. Now I tap it with a rod when it's still warm, and it flakes right off.

Warm tapping never stuck for me, it just spread the slag around. I wait until it's stone cold, then hit it with a heavy hammer. The thermal shock makes it pop off in sheets. Saves a ton of time over picking at it.

My 3-pound sledge on cold metal is my go-to move. It pops the slag off in one solid piece every time. No messing around with warm tapping anymore, lol. Saves so much cleanup time.
