+1 for gentle hose down and wipe after every ride to remove primarily salt at this time of year, plus any muck. Pay particular attention to wheel rims, chain, exposed gear cables, front and rear gears. I tend to wipe chain with damp cloth after every ride to remove salt residue, let it dry, and lube using Mickle method (Google it) with a PTFE wax grease. I did have some feedback from my LBS that this was leaving the chain a wee bit too dry, so have adjusted my wipe/lube ratio slightly to,leave slightly more on. Periodically a wee scrub down with hot soapy water and brush, followed by above also helps.
