Review on Borosilicate Glass Platform for Creality: 310x310x4mm by James Pfettscher

Note I have both the old and new versions. According to the product description, the bed should be cleaned with isopropyl or acetone. It is normal with coatings on old glass plates. The old version has a white screenprinted icon in the front right corner. There is nothing in the new version. Plain black finish with no shine. ABSOLUTELY FREE OF SOLVENTS. I tried 99% iso and it got sticky. After drying, it quickly returns to its normal state, but this is no longer the same coating. After wiping the surface with an alcohol wipe, visually noticeable stains remained, which did not disappear. I don't know what to think at the moment. Even.
