earlymb Posted June 6, 2016 Share Posted June 6, 2016 Just back on the forum, busy trying to get some work in, reading this I would say the solution was not strong enoughThe battery charger says fully automatic http://www.halfords.com/workshop-tools/garage-equipment/car-battery-chargers/halfords-fully-automatic-battery-charger So not sure if its the right type to use It's a slow process anyway. 8 amps should be enough for 20-30 liters of solution, but if you use 100 liters of solution you might need a more powerfull powersource and maybe add a few more anodes (the scrap metal connected together by an electric wire to the Plus of the battery charger). I've heard about someone using an electric welder as a power source for de-rusting a trailer chassis in a swimming pool... Quote Link to comment Share on other sites More sharing options...
GeePig Posted June 7, 2016 Share Posted June 7, 2016 Hi You are correct in the context of electrolysis the soda is there to promote electrolysis. But in the process look at ways to improve the rust removal I tried Heating the Water and in the process discovered that Washing Soda will also remove OD paint quiet nicely. I took a strong solution of washing soda and water in a pot filled with small parts and heated it in electric pot to 180-212 F let it cook for 1/2hour and then pressure washed them with 180F water and the paint all came off. Great way to process bolts small parts. Cheers Phil And maybe a rotating tub to ensure everything gets cleaned and the solution does not stagnate, and perhaps a built in pump and filter...? trevor Quote Link to comment Share on other sites More sharing options...
