solution for tank rust

weve been cleaning tanks with vinegar and baking soda for a while now and trust me this works, pour some baking soda in the tank first then fill it with vinegar, next grab a piece of metal and a battery charger, connect the positive to the piece of metal and make sure it only makes contact with the vinegar, DO NOT LET IT TOUCH ANYTHING, connect the negative anywhere outside the tank so it could make some ground, let it sit for a day and watch the majic happen, once its done, flush the solution out, rinse with gas to clean out the left over residue and fill it up with gas again, thatll keep it from rusting again, oh and make sure to always keep it full if u can, i did that with many tanks and they are still up and running,

I just read that at the end of another post at what amp are you using the chqarger or will a floating type tender/charger work its basicallt electrolosys they neutral lizw aluminum that way to anodise it if I remember right

u can leave it at 6 amps if ud like, usually does the trick, idk about the floating tender, never used one of those for the job.
