Hi Stripes

Well, you sent me digging. The chemical formula for ethylene glycol is C2H6O2. I can not see where any silicates are going to come from. I did run into some information that would lead one to believe that when antifreeze is mixed with tap water, as we do in cars, that carbonates are a virtual certainty. This would have about zero effect on cleaning engines, since we don't mix water with the antifreeze, except to rinse the parts off. Still.. it has been a long time since I took chemistry, and if silicates are a real possibility, I would be interested in knowing more.

Since we do not use antifreeze, except as a solvent, for our purposes, I doubt that the fact that it cleans bearings is of any importance. I guess we just need sure to get as much of the rinse water out and lube the heck out of things to insure the bearings, etc, don't rust.
