Winsor and Newton Drying Oils Mediums

A natural resin and oil emulsion containing ammonia, specifically formulated for cleaning varnished paintings. It effectively dissolves linseed oil oxidation and removes surface dirt and oxidation residues from old varnish.

Please note, however, that a painting requiring old varnish removal should be entrusted to a skilled picture restorer. Unvarnished artworks may also be treated with Artists’ Picture Cleaner. However, great care is essential, and the process should be halted immediately if any colour appears to be coming off the painting.
