No, looked around the house for some--couldn't find any.  Sounds strange, but true.

A fellow forum member explaine that coke contains phosphoric acid which does clean, so I found some 80% phospheric acid by merc of germany to buy, will test and report to you Gents.

Once soaked I brush with a toothbrush and powederd detergent, little water at first to scrub the powder on parts then brush under tap water. 

Vissin Fluid is the name of the stuff.

Is vissin different or more effective than alum?

That's the part I don't know. I've never used either. Somebody's going to have to chime in cuz I'd like to know myself.

There's several older posts on here regarding this. Here's one:

It's Sulfuric Acid. Vissin major distributor is Bergeon. It's toxic as all heck. More so when heated. I just found the MSDS (safety data sheet)

So no, Vissin is not the same as Alum, which seems ALOT less dangerous than Vissin and is available in any stores spice and ingredients section.
