Sprayway 50 is not a bad product, but Champion Sprayon Vista Cleer, is
ammonia, alcohol and silicone free. Sprayway has too much alcohol
added and can dull some surfaces and is not recommended for window
film. Vista Cleer is totally safe for just about any surface and will
never harm window film. I buy a ton of Vista Cleer from Sommer & Maca
or a few local janitorial distributors.
