Hey, apologies if this is a duplicate post - my search foo is pretty bad nowadays I think :< - but I wanted to ask how others clean PEI sheets?

I see a lot of rather conflicting information, in particular whether to use cleaning alcohol or not on it. I intuitively understand Acetone is a no-no, but what about just alcohol? Does that also damage/roughen the surface of the smooth side?

Should I use window cleaner on the smooth side?

Just dishwashing soap to be on the very safe side?

Or is there some specialized PEI cleaner?

Acetone is fine.

This is actually one of my pet peeves. Acetone is far from the “universal plastic solvent” that it has as a reputation…

Ultem, aka pei actually does great with acetone: https://www.astisensor.com/ultem.pdf.

I use acetone pretty regularly on my sheets and I haven’t noticed any bad effects. Usually it is best to use soap and water, acetone and isopropyl alcohol. If things won’t stick, do all three (in that order).
