I wonder if what your bike really needs is a new rear derailleur... The muck might have gotten into the pivot points and now the RD is sloppy.

FYI: At the bike co-op I've seen a number of post year 2000 bikes come in that won't shift properly. They've been clean and apparently low mileage bikes. And yet, the RD's have been sloppy. They'll usually shift correctly in one direction but not the other.
