how to clean this picture...?
I have a large 2X4 FT. cheap framed picture/print on paper that I love.! It has been hanging for years & needs cleaning other than the dusting it now gets. Is there anything I can use to clean it with without destroying the paper print? Everyone that first sees it thinks it is a painting til they see it up close but it is of no value to anyone except to me! I do have a few original oil paintings that I should try & clean too but am afraid to touch them also!
