The Evapo-Rust product I'm familiar with comes in quart or gallon jugs, and the part needs to be SUBMERGED in it, similar to the electrolysis tank.

Yeah the washing soda and phosphoric acid are getting harder to find due to environmental regulations.

Believe it or not BAKING soda is a workable substitute in the electrolysis tank.

Basically if it don't fit in the tank, you need a bigger tank.
