General Tips and Precautions for Cleaning Tupperware

Regardless of the method you choose, following some best practices will ensure you clean your containers effectively without causing damage.

1. Always Test First:

Before applying any cleaning agent (especially bleach or abrasive pastes) to the entire container, test it on a small, inconspicuous area, like the bottom exterior, to check for discoloration or damage.

2. Avoid Harsh Abrasives:

Steel wool, harsh scouring pads, and abrasive powdered cleaners can scratch plastic deeply. These scratches become havens for future stains and bacteria. The paper towel itself, or a paste used with it, is a much safer abrasive.

3. Prioritize Immediate Rinsing:

The best way to prevent stains is to rinse containers with cool water immediately after use. This prevents food particles and pigments from bonding to the plastic.

4. Dry Thoroughly Before Storage:

Always air-dry your containers completely with the lids off before putting them away. Trapped moisture can lead to mildew and odors.

5. Know When to Retire a Container:

If a container is deeply scratched, warped, or retains odors and stains after multiple cleaning attempts, it's time to recycle it. Deep scratches can harbor bacteria.
