Rachel,
Gretchen Anderson, Conservator at the Carnegie Museum of Natural 
History, and teacher of our Keeping Historic Houses & Museums Clean 
course suggests cleaning glass and plexi with isopropanol and deionized 
water. Use a microfiber cloth and use the liquid sparingly spraying it 
on the cloth, not on the glass.
