To remove varnish stains, you need to dissolve the varnish itself and wash off the resulting solution.

Preparations containing the appropriate soluble components will allow stains from varnish to be removed. In order to remove the most persistent varnish stains, you need gel stain removers that provide a long-lasting effect on the stain, or particularly strong solvents that provide fast but aggressive dissolution. After removing the varnish stain, the area where the cleaning was carried out must be thoroughly rinsed to wash away both the remaining dirt and the residue of the stain remover.
