Hi - I've had my new Trek 820 mountain bike 5 weeks and its a good day to wash the caked-on dirt off. I've rinsed it; then washed it with a soft dust brush & soapy car wash concentrate in lukewarm water, and a final rinse. Now I'm letting it air dry - its hot but lo humidity here today.
Did not soap wash the chain, just a rinsing.
Wondering if a wipedown with soft towel is a good idea - and do I need to lube / oil anything?
Thanks from Peter
