Oil painting to dust

Painting in the warehouse or hanging, will be stained with a layer of dust. If a painting is covered with dust, the ideal way to clean it is to buy a large and small pencil from an art supply store and brush off the dust with a brush. But remember, must see clearly before painting surface has cracked, loose part. If so, don’t touch those parts. Oil painting must not be wiped with a rag, more cannot use a wet rag, with a rag with soapy water more dangerous. The moisture will enter the delicate muscle lines of the painting and is not easy to come out. Older paintings also have a coat of varnish, which when combined with the moisture will produce a pale lime effect, like bleaching the work. Moisture can also cause the canvas to shrink irregularly, making it harder for paint to adhere evenly. If the problem is serious, seek professional advice.
