I need to clean some PLA residue off the bed, and IPA isn’t touching it.
I see people talking about using 2000 grit sandpaper to clean their PEI sheet. Where are people finding this stuff? The local hardware looks at me like I’m crazy when I ask about it. The finest grit they carry is 600.
If I do find some, do I wet-sand with IPA or diluted IPA?
