Re: Integral Tank Cleaning With Ammonia

[aquasonic]

quote Jim Moffatt:

Ammonia is a great tank cleaner and I use it all the time. However it attacks brass fairly quickly. It may eat away a brass or copper screen in a day or so.

Muncie/Nwptune tanks from the 30s have a thin brass tank neck and 3 days of ammonia in the tank caused it to be unusable. THe 30s omc tanks do not do this but I would limit the time its used to 1 to 2 days.

The presence of brass or copper is an important consideration. I saw the effect of ammonia on brass first hand when I put ammonia in a garden sprayer with brass fittings. I was trying to deter squirrels that were making a home in my attic.

That turned out to be a bad idea because the ammonia bothered me more than it bothered the squirrels, and the brass fittings on the sprayer just crumbled.

As far as all aluminum integral tanks go, I haven’t seen anything yet that works better than ammonia for cleaning old gas and oil deposits.
