How to clean mould from plastic kitchenware?

Nov 25, 2025

Hey there! If you're like me, you've probably dealt with the pesky problem of mould on your plastic kitchenware at some point. As a Kitchen Mould supplier, I've seen firsthand how mould can not only ruin the appearance of your kitchen items but also pose a health risk. In this blog post, I'm going to share some effective ways to clean mould from plastic kitchenware and keep your kitchen in tip - top shape.

Why Mould Forms on Plastic Kitchenware

First off, let's understand why mould loves to grow on our plastic kitchen stuff. Plastic is porous to some extent, and it can trap moisture and food particles. When there's a combination of moisture, warmth, and organic matter (like food residue), it creates the perfect breeding ground for mould. You might find mould on items like food containers, trash bins, or even spatulas that have been left in a damp environment.

Tools and Materials You'll Need

Before you start cleaning, gather these essential items:

  • Gloves: To protect your hands from any harsh chemicals and the mould itself.
  • A scrub brush or sponge: For scrubbing away the mould.
  • White vinegar: A natural and effective cleaner.
  • Baking soda: It's great for deodorizing and removing stubborn stains.
  • Lemon juice: Another natural alternative with antibacterial properties.
  • A bucket or sink: To soak the plastic items.

Step - by - Step Cleaning Process

1. Initial Rinse

Start by giving your plastic kitchenware a quick rinse under warm water. This helps to remove any loose debris or food particles on the surface. You don't want to scrub them in later and spread the dirt around.

2. Vinegar Soak

Fill your bucket or sink with a solution of one part white vinegar and three parts water. Place your mouldy plastic items in the solution and let them soak for at least 30 minutes. Vinegar is acidic, which helps to break down the mould. It's also a natural disinfectant, so it'll kill any bacteria along with the mould. While they're soaking, you can take a look at some of the great moulds we offer, like the Square Food Container Mould, which can help you create your own durable food containers.

3. Scrubbing

After the soak, put on your gloves and take out the items. Use a scrub brush or sponge to gently scrub the areas with mould. If the mould is stubborn, you can make a paste of baking soda and water. Apply the paste to the mouldy spots and let it sit for a few minutes before scrubbing. Baking soda is a mild abrasive, which helps to lift the mould from the plastic surface.

4. Lemon Juice Treatment

If you still see some traces of mould, squeeze some fresh lemon juice onto the affected areas. Lemon juice has natural antibacterial and antifungal properties. Let it sit for about 15 minutes, then rinse the item thoroughly under warm water. The lemon juice also leaves a fresh, citrusy smell.

5. Final Rinse and Drying

Give your plastic kitchenware a final rinse to make sure all the cleaner and mould particles are removed. Then, dry the items completely with a clean towel. Make sure they're completely dry before storing them, as any remaining moisture can lead to more mould growth.

Preventing Future Mould Growth

Cleaning the mould is one thing, but preventing it from coming back is equally important. Here are some tips:

  • Keep it dry: After using your plastic kitchenware, dry it thoroughly before putting it away. Don't leave wet items in a closed cabinet.
  • Regular cleaning: Make it a habit to clean your plastic items regularly, even if you don't see any mould. This helps to prevent the build - up of food residue and moisture.
  • Proper storage: Store your plastic kitchenware in a well - ventilated area. Avoid overcrowding the cabinets, as this can restrict air circulation.

Special Cases

Plastic Trash Bins

Trash bins are prone to mould because of the constant presence of waste and moisture. For Plastic Trash Bin Mould, you can follow the same cleaning process. However, since trash bins are larger, you might need to use a larger container for soaking. You can also sprinkle some baking soda at the bottom of the bin after cleaning to absorb any odours and moisture.

PP Food Containers

PP (polypropylene) food containers are popular because they're lightweight and durable. For Pp Food Container Mould, be gentle when scrubbing to avoid scratching the surface. Scratches can provide more places for mould to hide. You can also use a mild dish soap in addition to the vinegar and baking soda for a thorough clean.

When to Replace

Sometimes, the mould might be so deeply ingrained that cleaning won't do the trick. If you've tried all the cleaning methods and the mould keeps coming back, or if the plastic has become discoloured and brittle, it's probably time to replace the item. But hey, as a Kitchen Mould supplier, I can offer you high - quality moulds to create new and better plastic kitchenware.
