In addition, although the cleaner works fairly well, the cleaner leaves a heavy film on the bike which is fairly obvious on dark colors such as my black bike. This film might be hard to detect on lighter color bikes. The problem with the film is that it is difficult to remove and can not be rinsed off with clean water. In fact I normally need to wipe the bike down multiple times to remove the film.

I am sorry about the negativity but I just wanted to share my experience with this cleaner and I cannot continue to support a product where the spray bottle will no longer spray after only a single use.
