[Shop-talk] degressers

[Dave Cavanaugh]

What are you de-greasing, and what kind of finish is under the grease?  
When you spray the degreaser on and rinse it off, where is the runoff 
going to go?  (Hopefully not into your well...).

Years ago I used to use Gunk spray degreaser on nasty engines; it took a 
couple of applications sometimes but seemed to work pretty well.  I 
don't know if it's been reformulated to be more eco friendly or not; I 
haven't used it for years.

For really nasty stuff, oven cleaner works pretty well.  The stuff from 
the dollar store is as good as any.  The problem with oven cleaner 
(other than the obvious precautions to keep it out of your eyes and off 
your skin) are that it will remove paint as well,  and it's can discolor 
(at best) or dissolve (at worst) aluminum.  That being said, I have used 
it on a number of really nasty motorcycle engines and never had one 
dissolve or fall apart, although it did mess up the finish on one Honda 
engine.

Another alternative if your degreasing project is portable is to take it 
to your local coin operated car wash.  Some of them have "steam 
cleaners", actually hot water, for degreasing engines and 
undercarriages, and the good thing about most car washes is that they 
process the waste water.
