Are there any products/chemicals you use that "assist" your manual efforts in the cleaning of blocked cast iron boiler heat exchangers?

    My fave product

    Are you talking on the water or combustion side? The product I use to clean cast iron heat exchangers is a dolly to haul it outside and on to a truck to the scrap yard.  ; )
