Sodium bisulphate or pool PH minus as pickle


#1

Orchid Folks…

Was following the thread about using the pool chemical (in my case
the brand is called PH Minus, and it is 100% sodium bisulphate) as
pickle…

Those of you who use this stuff…what concentration do you mix it
up as, ounces per pint or whatever of water…

And do you use it at room temp or heated…?

Gary, I usually use a 2-quart Corning Ware casserole (deep) for
pickle. When I’m mixing my pH- pickle, I use a scant 1/3 cup of pH-
to 1-1/2 quarts of water.

I use it hot, but it also works at room temp (just slower).
However, I’ve found it best to mix it up hot – like most solutions,
it dissolves better and much more quickly when heated.

Hope this helps,
Karen

Hi Gary,

 Those of you who use this stuff....what concentration do you mix
it up as, ounces per pint or whatever of water... And do you use it
at room temp or heated....? 

I use a an old 4 quat crock pot as a pickle pot. I usually start out
with about 3 quarts of water & put in a cup of Ph Minus. I don’t
measure it, I just pour it in. I like to use the pickle warm, it
gives faster results if it’s warm.

I don’t think the actual amount of Ph Minus is that important for
the average bench jeweler; too little & pickling will take longer,
too much could be wasteful. For industrial applications though, it
might be a good idea to contact someone with an understanding of the
chemistry involved based on the makeup of the items being pickled.
