I write reviews normally rare, but this product is awesome. I bikers have put my helmet with visor for wintering on my motorcycle, my boys 2 and 4 years have left so many fingerprints and smudges on the visor, I Kopflos this cleaned with Sidolin. Of course that was the death, none 3 minutes on the head and it was followed by a steam bath. Continue with this helmet was impossible.
Product sprayed from both sides on the visor and during the specified exposure or drying time moved in to leave as little streaks, then polished with a dry cloth and lo and behold, the steam room is a thing of the past. The product is highly recommended.
