Your car’s exhaust pipes play a crucial role in the overall performance and safety of your vehicle, therefore, it’s vital to keep them clean and free of debris. 

However, using harsh chemicals found in commercial exhaust cleaners can harm both you and the environment. 

Fortunately, several natural products can effectively clean and maintain your car’s exhaust pipes without any negative impact.

Here are some natural cleaning products for you to try:

  1. Baking soda and water: Baking soda is a natural deodorizer and can be an effective cleaning agent for your exhaust pipes. Mix one tablespoon of baking soda with one cup of water and use a stiff-bristled brush to scrub the pipes. Baking soda can help to remove any buildup of grime or soot and leave the pipes smelling fresh.
  2. White vinegar: White vinegar is a natural cleaning agent that can effectively clean and maintain your car’s exhaust pipes. Apply a small amount of white vinegar to a cloth, and then gently scrub the pipes. Be sure to wipe the area clean with a damp cloth afterward.
  3. Lemon Juice: Lemon juice contains natural acids that can break down and remove dirt, grime, and built-up rust from exhaust pipes. Mix equal parts of lemon juice and water, apply it with a brush to the pipes, let it sit for a few minutes, and then rinse it off with water.
  4. Cornstarch: Cornstarch can act as a gentle abrasive to remove buildup on your exhaust pipes. Mix one part cornstarch with one part water and apply the mixture to the pipes with a brush. Scrub the pipes gently to remove the buildup, and then wipe the area clean with a damp cloth.
  5. Washing Soda: Washing soda, also known as sodium carbonate, is a natural, alkaline-based cleaner that can remove heavy-duty grime and rust from exhaust pipes. Mix a quarter cup of washing soda with a quart of warm water and use it to scrub the pipes with a stiff-bristled brush. Rinse the pipes with water after scrubbing.
