I’ve tried almost every method to remove rust from metal parts! In the above VIDEO I show my favorite method for removing rust from metal parts – specifically traditional woodworking hand tool parts – but it’ll work for most other metal parts, like auto parts. Click here to read the original blog post with links.
But first let me tell you about the other methods that haven’t worked very well for me:
-Electrolisys with a car battery charger didn’t work very well, and is quite difficult to setup
-Evaporust worked great the first time, but not so well when I bought a smaller container…go figure. But is really expensive.
-Krud Kutter didn’t work, and it’s expensive when you break it down to a per-ounce cost
-Vinegar sort of worked, but not perfectly…I had some strange issues with the metal afterwards
I hate rust because it causes corrosion and pitting on metal tools. So what worked the best at rust removal? A Citric Acid solution! Sound complicated or dangerous? Well, it’s not. It’s safe on the environment & hands, and it is the least expensive method I’ve found.
Supplies that you’ll need:
Here’s a list of everything that you’ll need to remove rust from your metal tools (visit my original post here to get links to the products that I use):
-Citric Acid (5 lb. bag will last you for a long time and is the most economical)
-Rubber gloves (will prevent pain if you have any cuts on your hands)
-Small wire brushes
-Mineral Spirits or Lacquer Thinner
-Zep Citrus Degreaser (I like the 1 gallon size) or Simple Green degreaser (I use Zep for removing grime from my road bikes)
-Spray bottle for the degreaser
-Oil or spray lubricant (I love this DuPont teflon chain-saver lube)
-Plastic container that will hold your metal parts (a used ice cream tub works great)
-Paper towels and a black towel (for quick drying)
-Place your metal parts into your plastic container and decide how much warm water you’ll need to add to just cover the parts
-Remove the parts and fill with the container with enough warm water to just cover the metal tool parts that you’ll add
-Add ¼ – ½ Cup of Citric Acid to the warm water while stirring…this creates a solution
-Stick your metal parts into the solution
-If you don’t see bubbles after a minute or two, just add another 1/4 cup of citric acid
-After an hour, use a wire brush to loosen the rust
-If it doesn’t loosen very well, leave it for another hour or two until it scrubs off more easily
-Quickly dry the parts with a large black towel and immediately lubricate with oil or spray lubricant…or else rust will appear within a couple minutes.
-That’s it! You may choose to polish the parts up since they’ll have a matte finish.
