PrimoChill Rad Clean - Radiator Cleaning Treatment

does the job - use it on every new rad

It doesn't matter who made your new rad or how much they claim to have "cleaned" it before packing it up and selling it - cleaning before use is a must. It's astonishing how much crud comes out of your expensive new rad. Don't let that crud get into your waterblock microchannels.

Works amazingly well to clean new n used rads out.
