Not sure if there's any science to support this idea but one of the only reasons I can think of to use a RCM every time is that, in theory, when you spin an lp, micro particles of plastic break off some micro peak and could then, if not removed, wind up getting lodged in some other sideways valley that make up the groves of the album. If you wash regularly, even every time if you're so inclined, you would probably remove those little pieces of debris.
I suppose if you're listening to the same lp over and over again (who's crazy?) washing it again and again may get ridiculous, but maybe you might want to get a couple of other records and musically change things up a bit.
Don't know if there's any damage done to an lp by washing too often but it seems at worse you waste a couple of minutes and some washing fluid but have a super clean lp.
Call me crazy, but you may not even have to worry about being called insane :)
