We have hard water here, so vinegar is good for cleaning. I soaked our
garden sprayer in vinegar for three days. I suppose the destruction of the
metal was the reason there was some reaction causing the vinegar to produce
gas. In any case, it appears to have destroyed the threads where the
sprayer attaches to the garden hose. The sprayer slips over the male end of
the garden hose now, loose.

So that's the way it's going to be with any cheap Chinese made garden
sprayer? No soakie in vinegar? Do I have to buy one made out of stainless
steel if it is to be soaked in vinegar? Or plastic, I guess.

What do you think the metal was that disintegrated?

Thanks.
