|Previous Tuesday, Nov. 20, I tried to wipe the curtain plastic enclosure around the optical table with the laser using methanol. It turned out, though, that methanol damages the surface of the enclosure, dissolving it and leaving lines/ traces. I stopped my activities with methanol after I realized that negative effect on three corner strips of enclosure. |
Lesson for everyone: NEVER USE METHANOL FOR THOSE CURTAINS!
I tried 25% solution of isopropil alcohol in water on Wednesday, Nov. 21, and such mixture did not have any bad effect on the surface of the enclosure. I wiped the curtains, so they should be clean of dust now.
