Burnout, why are you guys concerned about using a hose? I have read a few articles about washing bikes in cycle world and other reputable publications. The experts say to avoid high pressure water, like the do i yourself carwash and air, especially compressed air, you shoud dry by hand. Although I use my combination Rigid shop vac/leaf blower. works good.
also they say to avoid the handlebar area, switches and any electric components. On the max basically stay below the bars, faux tank, especially if you have flatslides, and seat. Wheels, engine, radiator, forks, swingarem, underside of rear fender is fair game.
In the articles I read they said diluted Simple green works well, do not use dish detergent. I have been using Simple green for 15 years and no problems. I t really works good on the heavy dirt, grime and brake dust. Works great on motor. Then spray with S100 and spray off for the final touch. She shines good. Hardly any hand work.
S100 also makes a product that is for gloss black painted painted parts only. It makes them blacker somehow. I never used it though. my paint hasnt really faded.
