He wouldn't share the ingredients with me because he said if I knew, then I could make it myself. It must be a pretty basic available chemical. If memory serves, this guy was some kind of chemical engineer and really knew his stuff. Many years ago I used a Dupont product that was very acidic and it had a neutralizer you had to use to kill the acid after you finished cleaning. I figured out the neutralizer was baking soda. The acid part would burn your skin. Well the EPA outlawed that and I had to find a good replacement and found this guy. The old Dupont product would make all the aluminum and brass parts shiny. The stuff I get from the other guy won't do that but it will cut all sorts of crud out of it. He assured me, I could leave it in for a week or more if I wanted to. I originally found this guy because I had an overheating problem with one of my corvettes. Corvettes don't have great cooling systems. After using this stuff in my vette and cleaning out the system, it ran about 30 degrees cooler. Another good thing about this is you don't have to neutralize it after your done. Just flush out the debris. I should have that information about where to get it later today.Hi 87Nassaublu
i would be interested in that website too, but my concern is that if he wont say what chemical are made of, is the cleaner safe for the engine?
That's why I used vinegar and not baking soda, but one could test it on some metals and see what chemical reactions take place and how strong they are.
Even with vinegar I got a lot of scaling removed with abundant brown foam, so at least it was doing something.
Then I would run it until it reached normal temp before waiting to flush again (after cooling), hence a slow tedious process taking up most of a day.
I have the other MEP to finish flushing also and if I can do it in half the time that would help.
When both MEPs are ready I will use the John Deer coolant as recommended here.
I never thought about using vinegar to clean a cooling system but I guess it would help. I've used it to clean old wrenches and files. That is sure a mess and it will stain your hands.
