[SEL] Best method for cleaning engine crud?

[Spencer Yost]

In a big tub mix one 12 oz can of pure Red Devil lye (getting hard to find
with the crystal meth epidemic) mixed with 4 gallons of warm water.  This
will strip anything that can be striped and is the safest way to remove
these old lead based paints.   Make sure the base metal is ferrous as it
eats aluminum, some brasses and bronzes etc.

Red Devil lye is Sodium Hydroxide.  Potassium hydroxide works too and can
be obtained through tanning supply places.   You must mix about 20%-40%
more of it to achieve the same level of effectiveness though.
