re:  Uncleanable, yellow coating on engines

"Aliphatic naptha" is the specified cleaning solvent for use with the
wax film corrosion inhibiting compounds such as LPS 3.  Whether this
will work after years of baking..?

Of course, naptha is highly flammable, toxic and many other bad things.
So be careful.

Dozens of flames, counter flames and he comes back with technical
details that are in fact a price list, all the while claiming it's a
hobby.  Too much for me.  Bye.
