Use a new spray bottle. Purchase" Ethyl Alcohol" from a drug store, not Isopropyl Alcohol! Pour about 1-2 Tbls of alcohol in sprayer, then fill bottle with distilled water. This formula is safe for tinted windows. Contrast this with products that contain ammonia which are not safe for tinted windows! Always use a clean, lint-free cloth, such as a micro-soft towel. Always wash window towels separate from other towels. Fold micro-fiber towel in half then in half again. Spray window and wipe entire section, then turn over towel and re-wipe. This removes any left over residue on the surface. Repeat this process for each window, always using 1st side of cloth to clean and the 2nd clean dry side of cloth to polish. As the towel gets dirty, unfold towel to the other clean sides and repeat process. This Window Cleaner is an excellent way to remove the plasticiser vapor on inside of front windshield... as explained in this blog article. Also check out Meltdown Bug Remover .
