I rinse my bikes every year or two.

Clean the chains every 3 or 4 months. Or maybe it's every 6-8 months...

Do the lube-and-wipe-off routine to the drive train and lube all moving bits every 3 or 4 weeks.

If there's a particularly nasty booger (like a dead worm or big glob of yuck) on a bike I'll use Simple Green and a paper towel.

Once in a great while I remember to wipe the frames down with Armor-All wipes.
