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.
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.
Use a knife and carefully scrape off what you can while cold. Heat to printing temp and wipe off what you can. Cool down and clean with acetone if need be.
Edit: do this only with metal pieces. Disassemble head if need be.
PLA basically doesn't dissolve in any (readily available consumer-grade) solvents. Your best bet is going to be to take the entire unit as far apart as you can until it is metal only components, heat it with a heatgun to make the PLA soft/melt, and brush it all off with a brass cleaning brush.

A SWAT team ready to mobilize, street level maps covering all of Florida, a pot of coffee, 12 Jammy Dodgers and a fez.

It's the second random post in which I find you randomly throwing Doctor Who quotes. They're so on point every time, love that :D

A wire brush. Handheld, not attached to an electric grinder or something like that.
Cheap wire brushes should be available in most hardware stores. I know that ours carries them in the paint section.
Remove the nozzle and hold it with pliers or something.

Think up every swear word you know, because you're gonna need them all.

And then rub it for three wishes.

If the head is all metal, soak it in acetone

Nuke it from orbit.
It's the only way to be sure.

What type of filament is that?
Maybe try a heatgun to soften it. I'm not sure, might damage the plastic casing.

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

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

Hrrmm. Does it still print? Personally I'd go with hope it kind of burns off over time with normal use. Others may disagree...

That certainly is one way to make it immediately worse, and welcome a whole cavalcade of failures throughout the machine. 🫣

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
