First off, has anyone done this to explain this process more clearly in detail?
Ive an old 'Good' Mz tank that has been fuel stored for no less than 25 years and Ive just started about cleaning it. It was 3/4 full of stale fuel, heavy sediment that looked like chewed blue roofing slate but black/brown and was removed totting up to a sizeable shovel full!!
Ive 'caustic' soda-ed it and made sure it was a lethally strong mix. Left for several days, that soup left a good satisfying 'Down Load' feel and so I washed it out which looked like creosote then another dozen times with clear water got it fairly clear. There were still stubbon lumps I couldnt reach so I used a 'Tank cleaner' but I wasnt as impressed with that stuff.
So, my next idea was to strip the 'grainy' but not overly thick although a lot of internal rust off using a solution of mild caustic soda water and a 12v power source, a 'waste' anode of mild steel was made which would run inside the tank on the positive lead whilst the tank was earthed on the negative.
Its working but vey slow. The 'anode' only seems to hold currrent for around 30 minutes then stops flowing a current because its dark brown in rust by then and needs cleaning back to bright. Surely at this rate Ill be an old man by the time this tanks spotless. There must be a far quicker way? Ive seen a few videos and they end up bright silver over just a few hours (like 8hrs) from heavy rust but not mine.
Question1, Would the anode be better made from another metal like iron?
2, Would a strip of stainless work better? I did read distantly it becomes toxic.
3, Would a different solution be better?
4, Run out of questions!!

. So It may be the same with motorbike tanks and so once you have removed the rust and as a result the coating you will need to find something to recoat it. As the MZ was a 2 stroke ? you could maybe put a high oil mx in the tank and slosh it round.
