What is Rust?

Rust is actually made of iron oxides, and is also referred to as “oxidation.” Scientifically speaking, rust occurs when oxygen and iron react in the presence of air moisture, or water. There are a few different kinds of rust that each feature a different chemical makeup.

According to, “corrosion of iron readily occurs in the alloy steel. The formation of reddish-brown flakes which loosely adhere to the iron is called rust.”

How to Remove Rust Stain from Carpet – Method # 1

  1. Upon discovering the rust stain, be sure to remove the source of the rust stain. If the rust stain came from the legs of a piece of furniture, consider moving the furniture to a new place, or placing a darker area rug underneath it to prevent future stains.
  2. Using a butter knife, scrape up any visible rust from the fibers. This scraping motion will initially help remove rust from carpet. Be careful not to rip the carpet fibers as you’re gently scraping.
  3. Pour dish soap onto a sponge. Blot the sponge directly onto the stain and let it soak for about 5 minutes.
  4. Using a white cloth (that you don’t mind disposing of or keeping as a rag) begin to press the rust stain, repeatedly blotting the affected area. The rust stain should gradually transfer directly onto the towel.
  5. If the rust stain still isn’t disappearing, mix 2 cups of warm water with 1 tablespoon of household ammonia.
  6. Pour the ammonia and water mixture directly onto the rust stain. Let this sit for about 5 minutes. Blot the stain with a clean portion of the white cloth.
  7. If the rust stain residue still remains, mix lemon juice, white vinegar and salt together and apply this mixture directly onto the rust stain. Let this sit for a few hours, and then blot with a damp towel. By carrying out the above mentioned steps in order, you won’t have to worry the next time you’re wondering how to get rust out of carpet.
