How to Use Stearic Acid in Rust Removal
Nothing is more frustrating then a rusty tool or other object. It is hard to use something once it has rusted over. However, it is possible to remove the rust and protect it from future damage. Stearic acid acts as a sealant over metal object to prevent them from oxidizing, which causes rust. It is very easy to apply stearic acid to any metal object, and it only takes a few minutes. Stearic acid can be found in the candle-making section of most craft stores, as it is often used to improve the appearance of candles and soap. Does this Spark an idea?

1
Examine the rusty object that you want to recover. Find the worst rust spots. It is important that the rust did not cause any holes to form in the object. If it has, then you probably will not be able to reuse the item even after the rust has been removed. If the rusty object is still intact, use the rust remover and a rag to rub the biggest rust spots first.

2
Remove the rust from the rest of the object. This is usually done by rubbing the rust remover into the rusty areas. However, if the rust is really bad, then it may be necessary to soak the object in a container of rust remover. This should be done for a few hours, depending on how bad the rust is. Remove the object when the rust has completely gone. Dry with a towel.

Open the stearic acid container. Stearic acid is generally used as an emulsifier, so it will be thick or oily in appearance. Do not get the acid in your eyes or near your face. Wear rubber gloves when handling the stearic acid.

Dip a rag into the stearic acid. Put enough on the rag so it is damp, but don't soak the rag. Smear the stearic acid onto the item that you want to protect from rust. Use a large amount at first to completely cover the object.

Rub the stearic acid into the object. Use circular motions. You will want to do this for several minutes. Try to absorb as much of the stearic acid into the object as possible. The stearic acid acts as a protector for the metal, so it is important to cover the entire metal object.

Wipe away the excess stearic acid with another dry rag. Set the metal object on a table or other surface to completely dry. Once the object is completely dry, you can use it for whatever task you had in mind. The object will now be protected from collecting future rust.
