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?
Windex actually works pretty well but I follow that up with some IPA just to remove any residue. IPA itself isn’t a great degreaser (apparently it just kinda smears things around), but it’s decent for surface maintenance.
I follow what prusa recommends, warm soapy water and a light scrubbing every so often. I actually haven’t done much to my satin sheet in months beyond IPA between prints, in my experience you’re pretty much the biggest source of oil that can be on your print surface so also practice not touching the surface as much as possible.
Check your paper towels as well, some brands have oils or softeners in them that undo all your cleaning
