I actually tried an electrolysis bath today using the 5% white vinegar. I didn't dilute it any further than what was in the jug from the store. Boy it is a lot faster with the charge from my solar panel. What normally takes several days was done in a couple hours so I might not need the washing soda after all. Kinda wished I took a before picture but the Briggs oil slinger metal was fully coated in rust. Don't look brand new but is definitely usable again. I just going need to redo it for 30 minutes as it came a cloud burst and it has flash rust on it. I didn't get to oil it first.
