How can an artists’ varnish be removed from a painting?
If the painting is particularly valuable then it should be taken to a conservator. Otherwise, the best product to use would be our Distilled Turpentine. Dip a lint free cloth into the turps and gently rub the surface of the painting. Start in a corner. The varnish should come off onto the cloth. If any colour can be seen on the cloth then you should stop. Working in small squares, proceed across the entire surface of the painting. It is best to keep using fresh pieces of cloth as this aids lifting the varnish rather than spreading it.
