Seeing Clearly Once Again!

I have used a couple of different products to flush my cooling system, because my heater core was clogged, and this is the one that worked the best! It removed the stuff that had my heater core clogged, and I can defrost my windshield once again!
I like this to much

Works well. Brings rust away from metal, into solution.

Used Blue Devil Flush on a '91 iron block motor that showed a lot of negligence. It brought out so much rust that I had to water-flush it 4 times to get it to drain somewhat clear.
I feel flushed!

Awesome!!
A great add on purchase to the head gasket sealer. Easy to use.
