kind of. I wrote “imo” to try and be polite.

one would be hard pressed to prove a “need” to power wash or hose wash a bike…..it’s more of an “I want to” thing. And that’s perfectly fine, but let’s not kid ourselves into thinking hosing down a bike is actually necessary unless the bike has been run through mud or crashed into a pile of dirt.
Which of course, brings us back to my original contention….that OCD is the driving factor behind wanting to go to the trouble/hassle of foaming, hosing down, and blow drying a bike just to get road dust off it.
