So my Traxxas Rusler is supposedly waterproof but I don't know if that means I can wash it with a hose?
Can I please have some suggestions on how to wash it?
Thanks.

I think pratically waterproof really means water resistant so no, I wouldn't douse it with a hose.

I'd take your time and clean it properly and take things apart and make sure all the nooks and crannies are nice and clean. You'd be amazed where crap gets into.

Bearings do not do well when they get wet. Just use a damp rag or compressed air to clean. Pledge with anti dust makes the chassis look new. Stay dry.

You'll be surprised how waterproof those Traxxas are. You can easily wash it off with a hose. But do at your own risk. Any water damage will void the warranty.
