How to Repair Plastic Using Baking Soda

Sodium bicarbonate is commonly known as baking soda. This multipurpose powder is useful in cooking, deodorizing and cleaning. Baking soda is a mild cleaning agent and is helpful in cleaning surfaces requiring a non-abrasive cleaner, such as fiberglass bathtubs and plastic containers. Combining it with another common household product, however, creates a strong bond that is useful in repairing plastics. Using baking soda to repair plastic materials is not a difficult process.

You can repair plastic with a baking soda mixture.
  1. Squirt a couple of drops of quick-setting glue--cyanoacrylate-- onto the crack, hole or dented surface of your plastic.

  2. Sprinkle a small amount of baking soda (enough to absorb the liquid) immediately onto the quick-setting glue. This will create a bonding material that fills the surface area.

  3. Repeat the method if the split, hole or dent is large.

  4. Sand the area with a medium-grit sandpaper after it dries, if necessary. This helps to create a smooth level surface.
