Yes, I have cleaned an engine with anti freeze. I got a Saito FA-65 that was on a plane that crashed in the woods and I could not find it. Ten months later someone found it and returned it to me. The parts with iron in them had some rust. I took the engine apart and put it in a crock pot with pure anti freeze and let it cook for 36 hours. It came out real clean and all the rust was gone. I have been told that this method of cleaning parts works well on almost all automotive parts that can be submersed in anti freeze.
