Auto Glass Oil Film Remover, Glass Cleaner, Strong Decomposition of Glass Oil Film, Remove Dirt, Water Stains. Suitable for (windshields, Mirrors, car Windows and Household Glass Products)

When I wash the car, it is always difficult to clean the stains, bird droppings and resin on the glass. Old waterproof membrane is more difficult to remove. This product is really great. All the above problems have been solved. After use, the glass is transparent and all stubborn stains have been removed. It's really great!

Needless to say, look at the pic: right (before) vs. left (after).

This is just a great product to clean and remove any dirt, oil, and previous water-repellent coatings. My windshield came out super clean like I just bought it from the dealer. And perfect for when I needed to apply the Glaco glass coating.Some of the review comments said they didn't understand how to use it. You can literally google this product and get the directions from the official SOFT99 website. And another review complained that it removed their old water-repellent coating...this product literally does what it intends to do...remove everything back to factory condition.That said, this is one of the best and easy to use products I have used.
