My little-used bike needed a good cleaning the other evening as it’s really dirty in this house in terms of dust accumulation. Changing the air filter helps of course but consider that this is the Mojave Desert, it’s a bit dusty around here!
This isn’t a $4000 bicycle but it does have an all-aluminum frame and other things such as the control cables being routed inside the frame when possible among other items. It’s a super light bike and has been well worth the $500 price tag.
I use what is called Waterless Carwash on the bike, the same polish and paint cleaner that I use on the truck. It’s a professional grade protectant with wax. Nice!
