If any of my bikes get grungy or muddy or road salted, I spray all over with hose and hit everything. I do not use a lot of pressure around the bb or head tube, etc...but I spray that sucker down. I then bounce the bike down the basement stairs and wipe dry with clean rags. Then I clean the nooks and crannies with simple green and then a light Windex spray all over and wipe with paper towels. After that I lube the chain and pivot points on the derailleurs and hang the bike by it's back wheel on a hook. I have never had any problems and do a deeper cleaning only when I do maintenance. I have done this for years on steel and carbon bikes. Life is short and bike cleaning is not that much fun.
