are picked up on the cotton balls and rubbed across the mirror in the next steps.
7.Completely submerge a cotton ball in the solution. Starting on one side of the mirror and using extremely light pressure, wipe the cotton ball across the aluminized surface in a straight line. Wipe just once, then discard the cotton ball. Submerge another cotton ball and wipe it across the mirror in a straight line right next to the first wipe, then discard this cotton ball.
8.Repeat this procedure using wet, clean cotton balls for each swipe until you’d cleaned the entire surface of the mirror.
9.Now rinse the aluminized surface of the mirror with room temperature distilled water; a gallon should suffice.
10.Let the mirror air dry in a warm place. Water will run off a clean surface, so keep the mirror slightly tilted while dry- ing. You can remove any random drops of water with the corner of a paper towel. When it is completely dry your mirror should be clean and spot free, and ready to rein- stall in the telescope.
