Hey Dave I’m glad you are going to try the electrolysis , I have tried several different types of rust removers over the years and found they are slow and messy and cost$$, I have not tried evaporust so I can’t speak on that.
Once I tried electrolysis I was amazed how fast it worked with little mess and not as much scrubbing afterwards to clean part, my electrolysis bath I made cost me $7.00 in total which will last me years of rust removal, I’m in the process of making a much larger one for my bigger projects.
I would have to say that I’m done with chemical rust removers and won’t be looking back.
