This Artist’s Picture Cleaner is a natural resin and oil emulsion, containing ammonia, and is ideal for use on varnished paintings. It dissolves linseed oil oxidation and removes surface dirt along with oxidation products from old varnish.
Shake well before and during use. Clean small areas with cotton wool pads, and once cleaning is complete, remove any remaining cleaner with distilled turpentine. For paintings that require old varnish removal, its best to consult a competent picture restorer. While unvarnished paintings can be treated with the medium, proceed with great care and stop immediately if any color appears to come off.
