I’ve had a MK4S for over a week now, and 100% of the prints I’ve tried to make on the textured sheets have partially or totally failed. PLA prints beautifully on the smooth sheet, but PLA, PETG and ABS, I think I could print on the surface of a 10 inch tank of oil with more success than the textured sheet. Plastic doesn’t stick to it. I’ve wiped it with isopopyl, I’ve washed it with dawn…it’s a bad print surface and I want my money back.
Grease is bad for those PEI sheets. I wipe it off with alcohol before every print. They need to be hot, too. Around the glass transition temperature of your material. I exclusively print PETG. 70°C will fail, while 85°C will stick great.
Glue stick on glass. Got it. I’ll go to Lowe’s first thing in the morning to get some cut to size.
Tbh I’ve used hairspray and glass with no issue as well. It cheap after and easy to clean. ¯\_(ツ)_/¯

I chipped so many glass beds back in the day with PLA and Elmer’s glue stick. I’d often put them in the freezer in hopes that they’d just release on their own. Alas, they chip there, too.
Witness if you will, the only two sheets of glass I’ve used since 2016:
