Understanding the Science Behind Cornstarch

Cornstarch, a common kitchen ingredient, possesses amazing absorbent properties. When mixed with cooking oil, it acts as a natural cleaner, effectively separating impurities from the oil. This natural and affordable method offers a sustainable solution to extend the lifespan of your cooking oil.

To clean your used cooking oil, you’ll need the following materials:

  • Used cooking oil
  • Cornstarch
  • Fine mesh strainer
  • Funnel
  • Glass container

Step 2: Cool the Used Cooking Oil

Allow the used cooking oil to cool completely before attempting to clean it. Hot oil can cause accidents and may not mix effectively with cornstarch.

Step 3: Add Cornstarch to the Oil

Once the oil has cooled, transfer it to a glass container. Gradually add cornstarch while stirring continuously. Aim to achieve a smooth, paste-like consistency.

Step 4: Strain the Mixture

Place a fine mesh strainer over another clean container or bowl. Pour the oil and cornstarch mixture through the strainer, allowing the clean oil to separate from any remaining impurities.
