<p>[QUOTE="mirana, post: 9560815, member: 79705"]I have been looking into conservation/restoration of oil paintings and varnish removal is just not a thing you should DIY. Besides the identifying of the varnish and paint compositions (sometimes requiring chemical analysis) the solutions used to do removal continue to be activated after varnish removal and must be neutralized. It must be removed in tiny like color sections with a mountain of fresh cotton. And it is done under magnification to make certain nothing is disturbed. A solution that works for one section may be a terrible thing on another pigment. It's not as easy as YouTube makes it look.</p><p><br /></p><p>I've read multiple book warnings that water should never be used in cleaning because it may wick into the ground material and cause paint to flake off later. Hopefully the varnish protected yours. Conservation books advise rubbing should never be done as it damages paint. They state a very light touch only, letting solutions do the work.[/QUOTE]</p><p><br /></p>
