Re: Engine cleaning


You lucked out in that you applied the stuff in cold weather.
Easy-Off has a goodly portion of lye in it(NaOH), which EATS aluminum
and magnesium.  Guess what your transaxle and engine cases are?
You're lucky you didn't end up with some large corroded spots.  In any
case you'd better paint things, you've probably taken off any
anodizing/surface treatment that existed.  I used to work in an
anodizing plant, they used a solution of NaOH for removing badly
anodized coatings from parts for another go-around, took about 5 mins.
at 90 degrees.  Untreated magnesium surfaces tend to disappear into a
pile of gray powder, pretty fast if you have some salt around(like on
the roads)  This Easy-Off stuff might work well with American large
car parts which tend to be ferrous, I'd still use a pressure washer
with some detergent instead.

Commercial firms can Alodine-coat aluminum and magnesium parts, this
is a proprietary gold-colored, chemically-applied coating, dipped or
sprayed on.  This might be what the original coating was.  It's
usually used under further paint or lacquer coatings to help with
adhesion.
