Cleaning Vinyl Use warm water and a clean cloth. Rub with a clean, damp cloth to remove dirt. You may have to do it more than once. 0 Things like tar, asphalt and shoe polish will stain if you don't get them off quickly. Use a clean cloth and a solvent-type vinyl cleaner. Cleaning Leather Use a soft cloth with lukewarm water and a mild soap or saddle soap. 0 For stubborn stains, use a mild solution of 10% isopropyl alcohol (rubbing alcohol) and 90% water. Never use oils, varnishes, solvent-based or abrasive cleaners, furniture polish or shoe polish on leather. 0 Soiled leather should be cleaned immediately. If dirt is allowed to work into finish, it can harm the leather. Cleaning the Top of the lnstrument Panel Use only mild soap and water to clean the top surfaces of the instrument panel. Sprays containing silicones or waxes may cause annoying reflections in the-windshield and even make it difficult to see through the windshield under certain conditions.
