From storing leftovers to organizing your pantry or meal prepping for the week, food storage containers are the unsung heroes of the kitchen. But not all containers are created equal, and neither are the cleaning methods they require. From stubborn tomato sauce stains to warped lids and those pesky, lingering odors, food containers come with a few challenges.
Our simple guide breaks down the best tips and tricks for proper cleaning, maximizing the lifespan of your storage containers, and keeping them safe and fresh for food items every day.
Know Your Container Type
Before diving into cleaning techniques, it’s essential to know what kind of container you’re working with. The two most common types are:
Plastic food storage containers are lightweight, affordable, and known for their convenience, but can be prone to stains, odors, and scratches.
Glass food storage containers are durable, microwave-safe, and resist odors and stains better, though they’re heavier and more fragile.
Knowing the proper use for each type ensures food safety and handling, maximizes the freshness of your food, and extends the longevity of your containers.
Master the Art of Proper Cleaning
For both types, we recommend using gentle cleaning products and avoiding high heat. Many Simply Done storage containers are dishwasher safe (top rack only).
Plastic Food Containers
- Wash with warm water and dish soap using a soft sponge to avoid creating scratches that can harbor bacteria.
- Always check for signs of damage, such as cracks or cloudiness. These can affect the integrity of the container and make it unsafe.
- Use white vinegar to remove lingering odors. Let it sit in the container for 15 minutes, rinse, then dry thoroughly.
Glass Food Storage Containers
- Safe for top rack in the dishwasher, but for best results, wash by hand to keep them looking like new.
- Use baking soda paste for stuck-on residue. Scrub gently with a non-abrasive sponge.
- Be cautious with sudden temperature changes (like from freezer to microwave). They can compromise the seal or even cause cracks.
Beat tough stains and odors
For stains
- Baking soda and dish soap paste: Scrub with a sponge and rinse with warm water to remove tough tomato stains and caked-on debris.
- White vinegar soak: Works well for both glass and plastic—neutralizes both stains and odors.
For odors
- Newspaper trick: Stuff crumpled newspaper into a clean, dry container and seal it overnight. The carbon from the ink on the newspaper absorbs any lingering smells.
- Lemon slices and warm water: Soak overnight for a fresh scent.
Maintain the lids and seals
Your containers are only as good as their lids. If they don’t seal properly, you risk leaks, contamination, and spoilage.
- Always hand-wash lids with dish soap and warm water. High heat can warp plastic lids, ruining their seal. When running through the dishwasher, place it on the top rack.
- Store with lids off or slightly ajar to prevent mildew or mold from forming inside.
- If your lid has a rubber gasket, remove and clean it regularly to prevent buildup and ensure a tight seal.
Store them the smart way
Maximize longevity by storing your plastic and glass food storage containers properly:
- Ensure that containers and lids are dry before placing them on a shelf, in a drawer, or in the pantry.
- Avoid stacking heavy items on top of plastic containers—this can cause cracks and warp the lid’s fit.
- Use dividers or organizers in your cabinet to keep jars, lids, and containers neat and prevent damage.
Know when to say goodbye
Even the most durable storage container has a lifespan. Be on the lookout for:
- Cracks or chips (especially in glass)
- Warped lids that don’t seal tightly
- Cloudiness or deep scratches in plastic that won’t go away
- Persistent odors that don’t fade with cleaning
- Signs of mold or mildew around seals or in corners
Using a damaged container can result in leaks, poor food safety, and even contamination. When in doubt, throw it out.
Extend lifespan with these power tricks
- Never place hot food directly into a container—let it cool slightly first. This protects the integrity of both plastic and glass.
- Avoid microwaving plastic unless it’s clearly labeled microwave-safe. Even then, steer clear of high-fat or acidic foods like tomato sauces. For these types of dishes, opt for glass as it is stain-resistant and can withstand higher temperatures for reheating.
- Label your containers with the date when storing leftovers in the fridge or freezer.
- Rotate your stock—use older containers first to avoid wear on just a few.
Clean the whole setup
Your sink, sponge, and dish brush can all affect your cleaning results. A dirty sponge spreads bacteria, making your hard work useless.
- Sanitize your sponge regularly—microwave it (wet) for 1 minute or soak it in white vinegar overnight.
- Clean your sink with baking soda and vinegar weekly.
- Store clean containers upside down on a towel or rack to dry before stacking or storing fully.
Proper cleaning and maintenance of your food storage containers ensures food safety and extends the longevity of your products. By following our tips and tricks and the proper storage and cleaning directions, you’re ensuring food safety and getting the best value from your containers.
