The corks were originally coated with shellac.Because the solvent for shellac is denatured alcohol,all gas with ethanol dissolves the coating.If the cork is in good shape I sand and brush it to remove loose flakes of old finish,then I brush on a coat of shellac to hold any loose bits in place and I only use ethanol free gas.
