Common Mistakes to Avoid

1. Using Harsh Abrasive Cleaners

Reason: Abrasive cleaners can scratch the plastic, making it more prone to harboring bacteria and stains over time.

Reason: High heat can warp or melt certain types of plastic, especially those not designed for dishwasher use, and damage the container.
Solution: Use warm or lukewarm water, and always check the plastic's heat resistance before washing.

3. Leaving Food Residue Behind

Reason: Food particles left in containers can cause odors to build up and lead to mold growth.
Solution: Always rinse and pre-clean containers immediately after use, before putting them in the dishwasher or washing them by hand.
