NO STREAKS. NO AMMONIA. Sun Shine is a highly concentrated glass cleaner built to leave windows genuinely clear instead of hazy and streaked. It cuts smudges, bug residue, fingerprints, and smoke film, and it is 100% ammonia free, so it is safe on tinted windows and display screens that ammonia based cleaners will stain and destroy. Paired with three Look Out glass towels, this kit is the whole glass job in one box. Ammonia free, tint safe: Most glass cleaners use ammonia, which stains and breaks down window tint over time. Sun Shine has none, so it is safe on tinted glass, LCD screens, and instrument panels. Concentrated, so it lasts: Dilute 3 parts water to 1 part Sun Shine. One 16 oz bottle fills the included 32 oz sprayer several times over. Use distilled water and you will get noticeably better results than tap. Two towels, not one: Three Look Out glass towels means you can run the two towel method every time. One to clean, one dry to level. That second pass is what separates clear glass from streaked glass. Work cool and in shade: Hot glass in direct sun flashes the product off before you can level it, and that is where streaks come from. Kit includes: (1) Sun Shine Glass Cleaner Concentrate, 16 oz. (1) Shine Supply 32 oz. Spray Bottle w/ Sun Shine Label (1) The Look Out Glass Towel, 3 Pack How to Use Dilute. Mix 3 parts water to 1 part Sun Shine in the included 32 oz bottle. Distilled water if you have it. Cool glass, shade. Never clean glass in direct sun or on a hot windshield. The product flashes off before you can level it and you will chase streaks all day. Spray and clean. Spray the glass and work it with one Look Out towel, edge to edge. On interior glass, spray the towel instead of the glass so you are not misting the dash. Level with a second towel. Immediately follow with a clean, dry Look Out towel to level any leftover residue. This is the step that makes it streak free, don't skip it. Get the top edge. Roll the windows down an inch or two and clean the strip that hides in the door seal. That edge is what shows when the window is up. Interior last. Work the inside of the windshield with your towel folded over your hand or a reach tool so you can get the base of the glass where it meets the dash.
