A chemical company can sell you the good stuff so to speak
Sometimes acetone (nail polish remover) is a stronger solvent - (we used to use it to remove urine from our microscopes)but it is possible it could damage/degrade some coatings or plastic parts near glass surfaces. Always wash it well off with water.
