I just bought a new heating element when that happened to me.
I might go back with some acetone now after reading others’ comments.
Not for PLA
OK, you’re gonna need some things:
A heat gun, A wire brush, Bandaids, A stiff drink
A SWAT team ready to mobilize, street level maps covering all of Florida, a pot of coffee, 12 Jammy Dodgers and a fez.
Mr. President, that man walked in here with a big blue box, and three of his friends. And, that’s the man he walked past. One of them is worth listening to.
I heated up the nozzle separately in some boiling water and scraped off almost all of it. Then I put it back into the hot end and heated it up to 200 C, took it back out and q-tipped off a lot of the rest. There’s still some but I’m running a print right now and it’s working fine.
Lick the frosting off…

I have heated it up just until plastic becomes malleable and used a damp cloth. I have also used a soft wire tooth brush to remove

This style wire toothbrush
Microwave
Metal piece with many pointy pieces and neodymium magnets in a microwave? The sparks will damage the item and the oven. And won’t melt the plastic
Think up every swear word you know, because you’re gonna need them all.

Nuke it from orbit.
It’s the only way to be sure.
If the head is all metal, soak it in acetone
Blow on it really hard.
