Glass cleaners contain chemicals, commonly acids and ammonia. I worry about their effect on the prints. Does anyone have good information on this and what do you all do? I clean mine using minimal amounts of glass cleaner where I must and rub as much off as I possibly can, then leave the glass to dry off/ evaporate for a day or two before use. Tim Hi Tim, I use a product Premium Clean Made by Tru Vue which sells picture framing glass. It is ammonia free, soap free, leaves no residue, static free and non streaking. I would ask your glass supplier what they have available. Cordially, John Harmon
