I believe brake parts cleaner will do as good a job without as much
scrubbing, one of the componants of it is naptha, it comes in a spray can
with quite a strong stream and will blow a lot of old crud off by itself.
The problem is it has to be used in a WELL ventilated area, or preferably
outside. It also comes in sprays that are non-polluting to the atmosphere,
non-chlorine formulas.

Those of you with old bowling alley for workbenches, it does not have a
crown at center but is made dead flat. My brother is a lifelong competetive
bowler and owns his own commercial bowling center. He not only has to make
sure they're flat but has to have them checked for flatness by an outside
source.
