Put on rubber gloves and safety goggles. In a large plastic tub, mix 1 part powdered citric acid and 10 parts warm water.
Immerse the tools in the citric acid bath, and soak them. If they are slightly rusty, soak them for several minutes. Severely rusted tools generally need to soak for at least an hour.
Scrape the tools with a plastic scrub brush. If some rust remains, return the tools to the citric acid bath, and soak them again. Alternate soaking and scrubbing until the tools are rust-free.
Fill a clean plastic tub with water, and add enough baking soda to make a cloudy solution. Dip the tools in the diluted baking soda to neutralize the citric acid residue.
Blot the tools with a towel, and let them air dry for several minutes. They must be completely dry before you store them.
