Has anyone used the 'citric' pickle? How does it work compared to
I had one instructor who swore by citric pickle - I used it in his
class for 10 days and it was just as satisfactory as Sparex. When he
needed to make a new batch, he poured the old citric pickle in a
plastic milk jug, set it inside a plastic trash can and let it
evaporate and then threw away the crystals.
Another instructor at a junior college used Ph Degreaser which he
got at a swimming pool supply place. He mixed it up in a very
saturated solution and only used it cold and it worked great. Unless
you were sweat soldering, you just dropped your piece in hot,
otherwise you quenched it in water first and then put in the Ph
Degreaser. He prefered using it cold because he said it didn’t create
fumes as hot Sparex did.
The instructor who used citric acid said he liked it better because
it didn’t corrode everthing around it. He had used it for years. So
I guess it’s a matter of personal preference and which is easier for
you to come by. I’m going to try the PhDegreaser as soon as I’ve used
up my present supply of Sparex which should be soon.
