After experimenting with electrolysis rust removal on small front suspension parts I wanted to try it out on something bigger. I didnt have any container big enough for my subframe but I had a few blocks and an old rideon mower cover.
Just water, 600g of baking soda, 12V from battery charger, some cheap jumper cables, negative to subframe and positive to an old sacrificial chainsaw bar.
Within minutes the bar started to fizz. Current draw was never more than 2A
After 4hrs rust sediment was visible.
How the subframe looked before I started.
Subframe after 1 day
Subframe after 2 days, I just power washed it to wash off the flakes of rust. Current draw had dropped way down to a point that could not be read.
While the subframe was doing its thing, got time to work on other parts.
Small tank.
Diff-Lock Actuator guard: Before
Diff-Lock Actuator guard: After 2 hrs
Rear ties, the both pretty much looked like this.
Half not done, Half done
After 4 hours
All cleaned up.
