Default How to remove rust from tools , parts, etc..



Advertise Here

Hi fellas and ladies. I've been doing this for years w/ old car parts and tools left rusted and ruined from Katrina.

This example removed the rust from a hundred year old Dietz "Little Wizzard" I picked up.

Things you'll need:

Plastic tub. YOu could use a pool if you needed to do this for a car chassis. Ask me how I know. LOL

Battery charger. NOt one of those trickle chargers. You need one that can do 2,12 or even 75 "jump starting" amps. The more the better.

A sacrificial anode. this is any sort of metal that will be sacrificed . I like to use a roll of screen because it can surround the object to be cleaned. It works on "line of sight" so the more metal surrounding , the better.

Baking soda or washing powder.

YOu will need 1 tbl spoon per gallon of water. More is no problem, but will not "speed up" the process.
Mix it up and place the screen or what ever you used as the sacrificial anode in the bucket.

Place rusted tool in bucket. Suspend it if you can , so it will be "visible" from all angles to the anode. DO NOT LET THEM TOUCH.

Use gloves if you have sensitive skin. I have never had any issue. even the bit of juice that jolts me isn't too bad, but then again, I used to stick my hands in all the time w/ o disconnecting. DON'T DO THAT!!! I now make sure to remove it properly and remove leads so i won't get shocked.

As for the leads, take the black (neg. - ) lead and connect it to a "clean" piece of the object. Make sure it gets a good contact.

Take the red (pos. + ) and connect it to the screen or what ever you have used.

Switch the charger to 12 amps (or what ever you have) and plug it in. I used the "jump" feature (75 amps) to speed the process up. I have no idea if this will shorten it's life going for so long, but it still works so experiment.

After a minute , you will see very tiny bubbles rising. IT'S WORKING!!!

Now I have read where they say it on;y takes a few hours, but I have gone for over 24 hours. sometimes I remove the object to reposition it if , say , the bottom was hidden by sitting on the bottom.

This is the lantern. Sorry some pics aren't that good.

Rusty lantern...



Tools used....



Fine bubbles rising...



After a couple of hours, it starts to get grody. A bit later it gets thicker. Skim this off.



Finished lamp w/ some clear to keep the rustic look.



For disposal, just dump. Completely safe for the environment.
Good luck!!!

Being similiar metals the free electron charged particles simply stay suspended in the water.
If you use a dissimiliar metal, the action might be a little different . Plating might occur .
Hot tanks have these issues, when people hang things with copper wire .
Colloidial silver is made similliarly, in distilled water, and lite voltages even 3 volts wil do it. .
sorry I get carried away.

I just came across several hand sickles as well. they're inexpensive to buy, but they are 30 years old, if they are a day. I'll post (better) pics of them as well.

I've got boxes of decades old tools I want to save from KAtrina. Just sooo much other stuff to do.

From what I understand, using any sort of metal works w/o issue. Some will say (and others argue it's not true) that galvanized puts off gas. that's what I've used as well as stainless, which I found lasts a bit more. either way, as long as you have the electrodes hooked up the correct way, no harm will come to the piece you salvaged. But yes it does act like reverse plating.

I have never used the electro method. Looks like you got great results.

I use wood bleach on old bike parts frequently with great results. You can get it at any old hardware store. Just mix it with warm water as instructed, and set your parts in. Most of the time I leave it for at least three days. Sometimes up to a week. It does not harm chrome plating or paint either. It would probably not work as well as the electro method on something as bad as that lantern though. It may take a few applications on something like that.
Remember to keep it outside though, as it will off gas.

Stainless for the anode is very bad and makes the water supply highly toxic.
http://antique-engines.com/stainless...electrodes.htm
Aluminum and copper anodes can also get rather messy so stay away from them. Zinc is also toxic and not anything to play with. Rebar and old steel wire fencing is what I use.

This process produces hydrogen gas. Don't smoke or have any open flames over the top of it. Might not be a good idea to do it inside either.

Laundry soda works better than baking soda. Easy enough to turn baking into laundry.
Take baking soda, spread it out onto a cookie sheet and bake it in the oven at a little over 300 degrees for an hour or so it will drive away a water and CO2 molecule thus making washing soda.
At temperatures above 300o* Fahrenheit (149o Celsius), baking soda decomposes into sodium carbonate, water, and carbon dioxide.
2NaHCO3 -> Na2Co3 + H20 + CO2
*

There is no danger in plating anything using this meathod. The only thing the 2 processes share is using voltage. I do this as well as nickle and copper plate things. Plating requires you to have a solution of the metal you want to plate with.

For my electroylsis setup I use a cell phone chargers. No need for anything bigger. The solution is only gonna take the current it needs and the extra is wasted as heat and a higher bill for the month. For large items I have used a car charger but normally those are thing like v8 car blocks in a few hundred gallon vat. A neighbor actually built a vat out of 4x4s and a pool liner to dip a vw bug in and it worked out good.

a nice side effect from your process is the hydrogen/flammable gas. those run your car on water ideas do this. IMO they don't work but if you needed some you could follow their guidelines to create a collector.

I am going to try this on some old hand tools though.
i am guessing, that this will remove surface rust but not the stains from it?

Thanks again

This method also works wonders on Mosin Nagant Barrels. I have had stuff come out of it that I could never get out using traditional bore brushes. The finished result is that it looks like it new. Thanks POPPALUV

This is definitely interesting.
Another method that I use for all my electrical tools, is WD40.
I spray down the tool, and wipe it and the rust just comes off. Repeat method untill tool is clean

Correct. this just removes the rust (down to the pits). If you have staining or paint, it won't touch that. that's one reason I do this for my classic car parts.

From what I've seen using WD-40 , it just removes some very loose scale, just as with a lot of elbow grease and steel wool. This method ELIMINATES all rust -even in nooks and crannies and pits.

In response to the gentlemen above who stated that the "voltage is voltage" and more isn't better- I did it again last night.
I did 5 minutes at 2 amps, 5 minutes at 12 amps and the rest on "jump" mode -75 amps. The difference was clearly visible. It went from a small stream of bubbles from a couple of places to flowing off of many more spots in much greater numbers.

Last night:





2 hours later...

Useing more amps will make is bubble more but the end results are the same. The process is gonna work the same and will stop when its done.
