Never wiped down a bike unless I've been riding through ploughed fields and it's got ten pounds of mud on it. The commuter and the fixie toy just drip-dry and get stored indoors. Never had a frame corrode badly because of it. Paintwork gets ratty, but I trash paintwork anyhow. Each bike gets properly washed maybe once a month. NO pressure washer, just hot soapy goodness and a big sponge.
