100% isopropyl alcohol. Submerge the mirror (aluminized
face up) in the water and let it soak for a few minutes (or hours
if it’s a very dirty mirror). Wipe the mirror under water with
clean cotton balls, using extremely light pressure and strok­
ing in straight lines across the mirror surface. Use one ball
for each wipe across the mirror. Then rinse the mirror under
a stream of lukewarm water. Any particles on the surface can
be swabbed gently with a series of cotton balls, each used
just one time. Dry the mirror surface with a stream of air (a
“blower bulb” works great). Cover the mirror surface with tis­
sue, and leave the mirror in a warm area until it is completely
dry before replacing it in the mirror cell and telescope. specifications
