Maybe you all know how to clean very rusted and corroded dug up war items, a hard slog by hand using a wire brush, a bench grinder with a wire brush, dust and crap everywhere...but a kind friend shared with me the easiest and maybe the cheapest way to remove all the crud on your items!
I enclose some images and the it I hope is self explanatory?
WHAT YOU NEED FOR THIS IS A PLASTIC CONTAINER/ A 12 VOLT BATTERY CHARGER/ 3- 4 STEEL PLATES/ THE CHEMICALS SODA CRYSTALS (AS IN THE IMAGES)/ AND SOME NORMAL SALT/ THEN THE ITEM TO BE DE-CORRODED/SAFETY GOGGLES-GLASSES/RUBBER GLOVES.
Depending the size of the item to be de-corroded (is this in the dictionary?) use only a plastic bucket / depending the size of the item- items/ find x3 or x4 steel plates 3mm-4mm thick , that will be suitable for the size of your plastic container. eg 8" long (so they stick out from the top of the plastic bucket for the clips) x 4" -5" wide.then submerge into the bucket making sure/ certain the that the item to be cleaned will be on the -
Negative side of the battery/ and the + Positive is connected to each plate by crocodile clips to the steel plates (anodes)
Once all is correct and connected up/ turn on the charger and try and get 2amps on the needle, add more soda if too low on the charger and should see the amps coming up to about 2amps and will see the bubbling start.
Keep your eye on the item being cleaned and you should see the rust coming of. Once you have left it in long enough, take out and rinse with plenty of water with maybe a little fairy liquid, rinse thoroughly, dry off, then it needs a thin coat of oil to protect them from going rusty once the air has got to them, or you can wrap them up after the oil in tinfoil, or primer them and then paint to the original colour....it should all stop the the rust starting again.....ANY QUESTIONS PLEASE E-MAIL ME AND I WILL TRY TO ADVISE YOU...THANKS...DESERT RAT!
THE LAST X2 IMAGES JUST ADDED ARE OF THE SODA CRYSTAL CLEAN...WHICH I UNDERSTAND WAS 8 AMPS ON THE CHARGER AND 12 HOURS IN THE DIP...BUT KEEP YOUR EYE ON IT AS THIS IS A FAST CLEAN (THANKS PETE)
