What do you do to clean off the baked on junk from the nozzle and bottom of the hot block? There is a mixture of PLA, ABS, and PET on there and it's hard. It doesn't really hurt anything but it looks messy so it would be nice to get it off of there.

I usually heat the nozzle to around 150C and pull it off with tweezers - comes off fairly easily when I do it.

I use a small fine brass wire brush. The type that is used to brush suede shoes. The brush head measures about 1" x 1/2".
I use it on my (brass) jhead. Couple of strokes at 230 deg C and it gets the black deposits off. Need to be careful about damaging the thermistor though.

I heat it up and use a small brass brush as well. These are brushes often used by welders.

msaeger: Yes. Mine is about the same size but with a plastic handle.
You want fine bristles so it is a gentle action. I can't tell from the photo.
