Hello... I have a LG PF1000 projector and it has a really delicate front surface mirror. Should I use these products for cleaning it? What's the % of the isopropyl alcohol? Thanks!
This is just a guess, but I would use 99% because there's no water in it. If you still have some spots and can submerge the piece (telescope primary or secondary), get a nice clean plastic pan, put some dawn dish soap in it. Don't overdo it. Disperse the soap by adding warm clean tap water. Submerge the mirror below the surface of the water face up. Take 6 turns of ordinary T paper and submerge this in the water. Once it's wet it will be so soft that you can very gently drag (not scrub) this across the coated face of the mirror. I don't use any circular motions, just a gentle drag from one side to the other. Repeat with fresh tissue if you need to. Nice and clean ? Remove the glass from the soapy water and rinse with tap water. Last rinse should be with distilled water. After this there will be a few small beads of water on the mirror's surface. Gently touch each water bead with a clean, dry paper towel (no scrubbing or wiping) and the surface will look like new. I've done this a lot and it works well. Important: Make believe this is like surgery. Clean everything before starting. Please note that some plastics have a small amount of oil in them, so clean your pan a few times.

I recommend 50% isopropyl (lens cleaner) and kim wipes
