Looking to do preventive maintenance on Yanmar 3YM series diesel. The raw water side gets calcium buildup and would like to hear opinions on flushing material. The process is to hook up a 12V pump to the raw water just before the elbow, going backwards and exiting just before the Raw water pump into the bucket with the pump.
There is Rydlyme, which is HCL plus some secret ingredients. Have also heard of "Barnacle Buster". Then again there is Phosphoric Acid easily gotten from a restaurant supply, and Sulphamic Acid is grout cleaner.
I've read dire warnings about not using one of the commercial mixtures, but don't understand how a commercial product with HCL is safe no matter what "buffering agent" is added to the mix.
What do you use for the raw water side?
