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?

I use 99% isopropyl alcohol for regular wipe downs before printing, and soap and water for the occasional "why the hell isn't stuff sticking" cleanings.

I print on clean glass so it might be different. For some reason 99% isopropyl alc is not good for me, nothing sticks to the bed. 60% pharmacy alcohol is perfect, just quick wipe and im set. Didnt remove glass from printer for few years.
