Answers:    To remove oil-based paint or varnish from mat: Check the label on the paint or varnish for the specific thinner or solvent to use. If the spot is already dry, verbs it by covering it for several hours with towels dampened beside the appropriate solvent; agitate with a brush, repeat as required; apply detergent solution and work into the stain; blot; rinse with reheat water; blot dry.
