You can either get rusty tools for a great price at a yard sale or flea market, or you can inherit them from your parents or grandparents. One day, you might need a wrench, hammer, or garden trowel, and realize that it's time to get them back in working order.

There are several ways to do that, as well as ways to keep rust at bay. Here is what to know.

How to remove rust from tools

Some of the ways to remove rust require more elbow grease than others. It depends on how much rust your tools have accumulated. There are some options.

Wash and sand

First, wash the tools in a tub of warm water with dish soap, making sure to wipe away any grease and dirt. The tools should be washed and dried. Depending on the extent of the rust, use a wire brush, steel wool, or a cloth to remove as much of it as possible.

Give it a soak

Once again, start by washing your tools in warm soapy water to remove grease and loose dirt. You should get a bucket or basin large enough to hold your tools. Put the tools in the bucket and pour some of the liquids over them.

  • White vinegar: Let the tools soak overnight or as long as 24 hours. You may need to use a wire brush or sandpaper to get the last remaining rust, but it should come off relatively easily.
  • Citric acid: For every gallon of hot water in the bucket, add 1/3 cup of citric acid. Mix the solution well, then add the tools and make sure they’re fully covered. Some tools will be ready in a few hours; others will have to soak overnight.
  • Oxalic acid: For every gallon of water, add three tablespoons of oxalic acid. Add and submerge the tools. Check them after 20 minutes. Leave them in a big longer if they aren’t quite there yet.

After the tools are done with their acid baths, rinse them off with clean water and dry them.

How to prevent new rust from forming

If your tools are close to it, double check that they are completely dry. If you want to seal the tool, you can spray or wipe on a small amount of oil. If you want extra protection, spray on a lacquer or clear coat.

To move forward, be sure to store your tools somewhere that is as dry as possible.
