All you need is a charger that isn't a complete piece of crap (horrible
fright being a near-guarantee of a complete pice of crap barring the
occasional planetary alignment - so killing that is an upside if you get
a better replacement.)

Use weaker solution or more distance between electrodes or a smaller
electrode if you are pulling too many amps for the charger.

I use my regular charger (don't recall the brand, but not Chinese) and
have had no trouble in 20 years - I can switch that one to 6V if it gets
too excited on 12V.

Ive used electrolytic derusting for a number of years now..and I try to
keep my voltage below 5 volts. Higher than that..and I find excessive
pitting.

Just a heads up.

You want a low voltage high current source. The reason being that you
need more currant the larger the item gets AND the stronger you make the
brine.

The normal method is to fill the tank with water, add in the parts, then
start adding the magic powder. Watch your amp meter while doing this and
stop adding powder when the meter stops climbing. This is saturation
point for that part. It is also the point at which the best cleaning
takes place. The problem is that it is also hard to adjust the mix once
you have it set. So what I generally do is to put in a mid sized part,
then mix, then just accept that smaller parts will need to be watched
and larger ones will take more time.
