Enzyme cleaners for tanks and blackwater pipes

[jmslomangmail.com]

I've read a number of threads on this forum regarding using enzyme cleaners for holding tanks and pipes, but I'm cruising outside the US and haven't found any of the enzyme cleaning products referenced. I have a stainless steel holding tank, fresh water flush and no toilet paper gets flushed. In order to clean the accumulated waste in the tank and pipes that I assume must be there after 14 years of use, I'm looking at using enzyme tablets available from a janitorial supplies company in the UK (BioHygiene - Urinal & Toilet Cleaner) i.e not made specifically for boats. Is this a bad idea? Thanks for your advice!

The issues with household and commercial toilet cleaners is their negative affect on the rubber and plastic parts in most sanitation systems.

I've not tried it yet, however, dishwasher detergent may be an option since is its designed to loosen dried grease and food debris from dishes. Throw some in the tank and go sailing letting the boats motion agitate the cleaning solution.
