How do you clean a smooth or textured PEI sheet? (self.3dprinting)

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?

Used both smooth and textured (stopped using smooth once i started using textured) and i just wipe it with IPA sometimes and if its really filthy i wash it with water and dishsoap. Never needed to “rejuvenate” them or whatnot and i print PLA and PET. The smooth one had hundreds upon hundreds prints in the middle of it and besides a little “ghosting” from last few prints it looks and works like new.

Acetone might be fine but having a spray bottle of ipa is much more useful than a bottle of acetone.
