Designed for cleaning brushes used in the application of U-40 rod finishes. Equally effective on all polymers; urethanes or epoxies, before they are cured. It will not effect the cured polymers of either group. Excellent for cleaning dirty rods or for wiping rod blanks prior to wrapping the windings and decorative wraps. Brushes can be dipped in Brush Cleaner, then squeezed dry onto a paper towel. If desired, brushes may be left standing in the solvent.
