I do not know how the people who distributed the bad reviews here, so clean your car? Dry or what? So I do not know any better than to Sonax Insect Remover. It is, of course, like any sensible underwear, appropriate pre-cleaning ritual so. That is, one assumes, the first thing the HD-lance at hand and sprayed the truck off to abzubekommen coarse dirt. Simultaneously, the dried insect remains to solve partially. The SONAX Insect here only to assist in dissolving the protein contained in the carcasses used. When the good as 10 - 15min. not allowed to act in the sun, you need only wipe the submerged in soapy water Waschhandschuh the surface of the paint and voila, everything wech! For the most extreme cases I can only recommend the clay bar from Petzold's.
