This baking soda trick works best on containers made from high-density polyethylene (HDPE) and polypropylene (PP), which are common in kitchenware due to their durability and resistance to heat. These plastics have pores that can trap stains, making them ideal candidates for this method.
However, this method can also be effective on other types of plastic, provided they are not overly scratched or degraded. It’s always a good idea to test a small, inconspicuous area first if you’re unsure about the material.
8. Common Mistakes That Make Red Stains Even Worse
One common mistake is using harsh scrubbers or abrasive cleaners that can scratch the surface of the plastic, making future stains even more difficult to remove. Another mistake is using hot water or dishwashers with high temperatures that can warp the plastic and open up the pores further.
Additionally, using acidic cleaners like vinegar or lemon juice can sometimes set the stain further, especially if not rinsed properly. It’s best to avoid these methods and stick to baking soda for a gentle yet effective cleaning.
