In no case !!!!. Not a soap or detergent sredstv.Vse to a greater or lesser extent contain alkali which makes the paint layer faded. And the water for washing soap penetrate through craquelure and lagoons to the ground can destroy it in the process of drying.
After a thorough examination of the paint layer and the canvas with a soft brush remove dust. Then a soft, slightly damp cloth in small patches can be wiped painting starting with pereferii.Vodu better take distilirovannuyu.Obrabotannye areas must be dried with paper towels, easily promakaya.Ne we should try to totally clean -- only the topmost layer. Next - the patina of time. The next stage - drawing on the painting surface a minimal amount of linseed oil, semi-dry brush followed by a slight promakivaniem paper towel if there is neobhodimost.Vse be done slowly and in line with the nature of the pictorial layer and the degree of pollution.
If painting requires more cleaning to do this is a proven professional with a fixation of all stages of the photo and obtaining the consent of the owner. The same is coated with varnish.
