Say Goodbye to Stained Containers with These Easy Tricks

From the Genius House Hacks archive.

A stained plastic food storage container

If you have ever opened a cabinet and spotted a stained plastic container staring back at you, you know the struggle. Tomato sauce, curry, berries, and even leftover chili love to leave their mark. The good news is that you can bring those containers back to life with a few simple tricks that work surprisingly well.

Scrub Stains Out With a Baking Soda Paste

Sprinkle a generous amount of baking soda directly on the stained area, then add just enough water to form a paste. Let it sit for about fifteen minutes, then scrub with a sponge. Baking soda is mildly abrasive, so it gently removes discoloration without damaging the plastic.

Soak in Dish Soap First for Stubborn Stains

Fill the container with warm soapy water and let it soak for a couple of hours. This softens any greasy residue and makes the stain easier to remove. Once it soaks, wash it like normal and many stains fade dramatically.

Try a Vinegar and Lemon Soak

Mix equal parts white vinegar and warm water, then soak the container for about thirty minutes. Vinegar cuts through trapped odors too, so it leaves the container smelling fresh. Add a squeeze of lemon juice for a boost; lemon's natural bleaching qualities brighten the plastic with a clean, citrus scent.

Lift Deep Stains With Hydrogen Peroxide

Pour enough hydrogen peroxide into the container to cover the stain, add a teaspoon of baking soda, and let the mixture sit for an hour. This combo lifts deep stains and lightens the plastic at the same time. Rinse thoroughly when you are done.

Let Sunshine Fade the Stain Naturally

After washing the container, place it outside in direct sunlight for a few hours. Natural UV light helps fade stains and brighten the plastic, and it is surprisingly effective, especially for tomato-based stains.

Scrub With Ice and Coarse Salt

Add a handful of ice cubes and a few tablespoons of coarse salt to the container, then swirl everything around. The friction from the salt and ice helps scrub away stains without harsh chemicals.

Prevent Future Stains With a Light Oil Coating

Lightly spray your plastic container with cooking oil before adding foods that tend to stain. This creates a thin barrier that keeps sauces from bonding to the plastic. Letting hot foods cool before storing them also helps, since heat makes staining more likely.

With a few of these tricks in your back pocket, your plastic containers can look almost brand new again.
