How do you remove silicone without damaging surface surface is wood varnished?
There are several brands of silicone remover on the market
today, (screw-fix has one) If you decide to use one of these
products, pay close attention to the hazards and warnings.
As for myself, I would use a razor blade to remove the bulk of
the material, (very carefully skim the surface) now hold the blade
perpendicular to the surface and "GENTLY" scrape the surface, if
done properly you will remove the silicone and a micro layer of
varnish (without removing the whole layer of varnish), keep in mind
the silicone could haved stained the varnish and spot removal of
the finish must be reapplied.
