I somewhat doubt CLR would do much - probably need some industrial strength stuff to shift that - then there is the risk of loose gunk getting into the water pump and jamming that up. Good luck.

Since the pump is off I hope it would flush out. The radiator flush from Prestone uses sodium citrate and says it isn't acidic. CLR says not to get it on your flesh so I figure it might be stronger. Could be wrong. I'm leaning toward muriatic acid but would water it down. DON TX   [Reply]  [No Email]
