How to remove stains from hotplate stirrer
Recently, I was conducting and experiment that required me to set the temperature of the hotplate quite high (380°C). Unfortunately, I accidently
left a plastic disposable pipette on the hotplate(Stupid me) and the pipette melted all over the hotplate. Now the plastic has become a hard and
unremovable lump. Does anyone have any suggestion on how to remove it?

The best way is to crank up the heat, let the plastic burn and it will eventually come off with a scratchy sponge when cool or after some further use.

To clean an aluminium hotplate from stains you can warm it to 50-80°C and wipe it with a piece of paper/sponge wet with diluted NaOH. It will
dissolve the surface and remove many stains. Just rinse it quickly afterwards or it could ruin the surface.
