We all know about Pledge and S100, Simple Green and various other cleaners out there, but the question I pose today is about water spots. Occasionally we must all deep clean our bikes and the only way to do this is with good old fashion soap, water and elbow grease. Now I use S100 and mild scrub brushes on the engine and wheels, for the rest of the bike I use a little Simple Green, water and a soft rag. After a good rinse and blow down with a bike blower (warm air) I still end up with water spots all over the bike that I must wipe off. So how or what do you use to prevent water spots? I have tried various soaps in the past and still I end up with spots. I got tell you it is driving me nuts. I spend more time removing the spots than anything else.
