Step 1
Mix the acid/water solution, adding the acid to the water. Using hot or warm water will help speed the chemical reaction. One-quarter cup citric acid to one gallon of water results in a light concentration suitable for lightly rusted articles.
Step 2
Prepare a solution of one-gallon warm water and one-quarter cup baking soda.
Step 3
Clean the rust covered item thoroughly, removing any grease, oil or paint.
Step 4
Place the article into the acid solution and watch for bubbles to start rising, indicating that the chemical process is working.
Step 5
Remove the article from the acid bath and, while rinsing under clear water, use a brush or scouring pad to remove the rust and dirt. Return to the acid bath if necessary.
Step 6
Submerge the rust free article in the solution of water and baking soda to neutralize any remaining acid. Rinse again under clean running water.
Step 7
Dry the item thoroughly.
