A friend of mine is cleaning up an original brass radiator that appears to have lime residue from
water used for cooling. Has anyone used this product which is for cleaning bathroom ceramic?
Thanks for any input.
I'd be pretty careful about using a product intended for tile in a radiator. In fact, I wouldn't.
I have heard some say that dishwasher detergent works pretty well.
I put 1/2 a cup in an original model AA rad
ran the truck for 10 min and drained it
no problem, I then left the pet cock open put some more in and ran the hose to it , eventually ran clean , and never had another overheating issue
I use LIME OUT
but I can't guarantee the results for you
I have used CLR with fairly good results. The rinsing out of all the residue is the most important concern. Once you introduce a chemical into your radiator you must get it flushed out plus all the gunk you loosened up by adding that chemical. If you don't get it all out you'll just plug up and over heat again.
Steve Jelf has some interesting videos of his radiator cleanout experiences on YouTube:
