fox_forma Posted February 23, 2007 Report Share Posted February 23, 2007 I saw something on spike tv i believe on one of their auto shows but cant exactly remember the episode or how exactly they were cleaning old parts. They put them in a container filled with something, dont think it was water, but they put a rod in the corner of it and hooked up a trickle charger on the 2amp setting and it cleaned all the old grime and rust off of the part. Sounds kinda vague but I have no other way of explaining it. Anyone have any idea what I am talking about and how exactly is works? Quote Link to comment Share on other sites More sharing options...
escgoodwin Posted February 24, 2007 Report Share Posted February 24, 2007 Yeah I saw that too. It was either sodium carbonate or sodium bicarbonate... Quote Link to comment Share on other sites More sharing options...
Bowtie70SS Posted February 24, 2007 Report Share Posted February 24, 2007 Muratic acid works well and is available at Home Depot. The Eastwood company has that cleaning kit you saw. Dave Quote Link to comment Share on other sites More sharing options...
fox_forma Posted February 24, 2007 Author Report Share Posted February 24, 2007 but what exactly is the process? I only caught pieces of it so I'm a little unsure of what they were actually doing Quote Link to comment Share on other sites More sharing options...
kissfans03ss Posted February 24, 2007 Report Share Posted February 24, 2007 I think they are gonna run that episode this satuday morning,i dont remember the specifics but it involves a trickle charger and 2 days time.You can also check the latest issue of old skool rodz,they did a cheap trick feature in the back of the magazine on the same subject.

misterp Posted February 24, 2007 Report Share Posted February 24, 2007 (edited) Mix a solution of washing soda and water (1 tablespoon per gallon) in a non-metal container large enough to immerse the rusty part; warm water works best. Put your part into the solution, and a similar sized piece of iron or steel with it. Attach the NEGATIVE LEAD TO THE PART, and the positive lead to the extra piece of metal, and turn on the charger to start the electrolysis. The process will attract the rust from the negatively charged part to the positively charged scrap steel electrode, meaning that the positive elecrode will be consumed in the process so make sure that you've got the polarity right and be sure that your electrode is as large as the part or larger (don't use a bolt to try and derust a bumper).

Mr. P. good stuff but wouldnt the neg be in the solution when connected to the part? Is that ok? Quote Link to comment Share on other sites More sharing options...

Mr. P. If you use stainless steel for the sacrificial electrode it lasts a lot longer. Another method is unrefined molasses, yeah that's right. Believe it or not if you leave a rusted part submerged in molasses for a week or so it removes the rust and corrosion. Chemistry is some cool shit!!

misterp Posted February 24, 2007 Report Share Posted February 24, 2007 good stuff but wouldnt the neg be in the solution when connected to the part? Is that ok?Yes that's what you want - it's the positive clamp that you need to keep out of the solution -or- make sure it's non-ferrous.

Dave I'm a believer that chemistry and timing is everything Where does a guy get unrefined molasses? Quote Link to comment Share on other sites More sharing options...
CoolBlueSS Posted February 24, 2007 Report Share Posted February 24, 2007 I remember reading about that years ago. Interesting about unrefined molasses. Coca Cola is good for removing corrosion. Quote Link to comment Share on other sites More sharing options...
