I have an oil painting that is framed but not under glass. Can it be cleaned?

The mat is quite dusty but I am afraid to do anything to it because I do not want to damage the painting. Please help.I have an oil painting that is framed but not under glass. Can it be cleaned?
Yes it can be cleaned. If it is a good oil painting take it to a good gallery and they can advise you. You normally do not put paintings under glass.I have an oil painting that is framed but not under glass. Can it be cleaned?
Do not put an oil painting under glass. Humidity will collect and the paint will stick to the glass, ruining the painting.
um.... i lost after u asked if u could clean it.
yes just use a little bit of rubbing alcohol diluted with water. Then rinse off any excess with 94 octane unleaded gasoline. Oh, and make sure you have a cigarette in your mouth while you're doing all of this.
Consult a professional in art work before doing anything.
Of course an oil painting can be cleaned. But since the various colours are made of different materials, each of them will need a different method of cleaning. My advise is let an expert do it! Any arts museum have a person for such jobs. Ask them.
Sure as long as the paint is dry - If you're just paranoid you could use a dry cloth or duster - but really oil and water don't mix. I wouldn't want to get it super wet just to preserve the actual canvas but it won't hurt it to use a damp cloth all over if you wanted. Oil paintings are often displayed without any glass cover and most people just dust 'em dry.
