If its confession time with regard to the use of household appliances and
fittings for engine building, the best place to wash a crank before use is
in the bath. Just lay a clean section of ply-wood in first to stop the
counterweights marking the porcelain and go for it. Plenty of fresh clean
hot water on hand for washing and rinsing, easy to totally submerge the
whole shaft. You would be amazed at the crap the that comes out of the oil
drillings from a core brush scrubbing. The other cheap household item that
works real good is one of those rounded toilet brushes for scrubbing freshly
machined cylinder bores. Your wife never fails to be impressed initially
when you show up from the store with this item under your arm and a grin on
your face.
