After trying a few things over the past week because I couldn't

find any Simple Green (what I've normally used in the

past), I ran across some stuff made by Zep.  They've got a 

humongous product line (almost looks as if Home Depot has a

business relationship with them per the litany of products 

by them they had available).  Looking for the heaviest-duty stuff

they had, I went for their Industrial Cleaner/Degreaser.  

It looks and smells identical to the Coastal Super Power Clean

that's found in automotive chain stores (deep purple colour).  

This stuff is quite caustic; it burns the skin with prolonged

contact and only after a few seconds it will dry the oil 

right off, leaving your skin dry. After dunking the engine rotors in

for less than two hours in a diluted mix (one gallon water and 

one gallon Zep cleaner), the carbon was just eaten away. About

15 minutes of brushing and voila -> brand new looking, 

silver-coloured rotors. They're so clean they're already beginning to

develop surface rust!

Hello:
Do you think this stuff could be sprayed/poured into a motor to 
unstick some apex seals and then flushed with water, gas, etc,
for car use?

Fascinating idea. I think it would be worth a try as usually the engine 
would have to be disassembled anyway.
Anybody got a stuck engine lying around?
