How to Clean Picture Frames
Lightly wipe the frame and glass with a soft, lint-free cloth. (Some picture frames, particularly antiques, have finishes that can be damaged by cleaning solutions.) To remove smudges on the glass, rub it with newspaper or a paper towel dipped in a solution of one part white vinegar and one part warm water. Let air-dry.
Care Tip: To prevent photos from sticking to glass, use a mat to create an air space between the two surfaces.
