Re: low voltage rust removal I have just given electrolysis a go on some small parts and it works great. I use a 12V 6amp battery charger and a decent splash of washing soda mixed into the water. there's good video's on youtube too. keep the water volume as small as you can and turn the pieces mid way through to get an even clean. good luck.

Re: low voltage rust removal Be careful what parts you derust using this method. This method causes Hydrogen embrittlement in various metals. Any parts you don't want to break while your driving, I wouldn't use this method to derust. See link http://en.wikipedia.org/wiki/Hydrogen_embrittlement

Re: low voltage rust removal I read the wiki article and it seems to me if hi strength and low strength steels are the problem maybe we should forget the process. It even said acid phosforizing removal treatments are bad. I wouldn't want the ears on my carb to break off, or manifold , from engine vibration or even mounting areas of sheet metal. Am I over reacting here? Bill G

Re: low voltage rust removal I personally wouldn't use it on any of my parts since there are less harsh alternatives but the real hazard could be in safety parts such as spindles, axles, steering parts etc.

Re: low voltage rust removal Sorry about this post on an old thread. Somehow I hit the wrong link and I was back in time about 8 years! Time for back to the future again!
I like to use agricultural molasses. It works by chelation, which is worth looking up on the internet. Apparently there are tiny 'things' in the molasses that actually eat the rust. Sounds like snake oil but it works well and does not hurt the metal or make it brittle. Check it out, 'rust removal by molasses' just might work. Another thing, most of these processes work better with a bit of heat but slow down if it is cold. |

It sounds like a great way to remove rust from an engine block or cylinder head. |
Re: low voltage rust removal Additional info on molasses from 2014... you MAy want to investigate before using it.
From what I remember there are different types of molasses and it makes a difference how long cast iron is left in the solution. Different ideas pro and con ... See post #9 ... https://www.fordbarn.com/forum/showt...s+rust+removal |
