RE: Cleaning the risers on 3208N

I used CLR to clean rust/scale out of an oil cooler assembly on my one Detroit; seemed fairly mild, but a lot of rust came out & things look pretty good. Rydlime is another possible product I have heard of people using. TRAC-Online has a product called Barnacle Buster that is supposed to be fairly good as well. I have used their Sew Clean with good success on our holding tank & head system. Not cheap tho'
