How to Clean Plastic Food Containers


  1. Koye says:

    Plastic food storage containers are notorious for staining when any tomato product is stored in them (spaghetti sauce, etc.). Wash the container, then put it out in the sun for a few hours. Re-wash, and the stain should be gone or at least faded to a point that isn’t offensive.

    Before putting any type to tomato-based sauce or product into plastic containers, spray the container with Pam or any other cooking spray.

    When you wash, the stain will be cleaned away.

    Pouring seltzer into a stained plastic container pulls all of the stain out. If necessary, use a brush to scrub it (an old toothbrush works fine).

    Seltzer is also a great way to clean stainless steel. Wash it first, then pour the seltzer on a soft cloth, wipe down the stainless steel and dry it. Only way I know to clean my refrigerator.

    I have many uses for Oxi-clean. I put a solution of it mixed with water in stained containers. It usually cleans them out with no scrubbing.

    To get plastic containers totally grease-free, I use Dawn ultra detergent in very hot water. It is the best dish washing liquid to remove all grease and oil especially from plastic containers. Make sure to insert your sponge or dishcloth into the container and twirl the container around several times with the cloth or sponge pressed tightly against the entire inside of the container… also make sure to reach the rim where the bottom of the container meets the sides, otherwise grease or food residue will still be there. Rinse the item very well also in hot water so that no detergent residue remains on the plastic. Air dry (in sunlight if possible) or dry well with a clean cloth.

    I use a 1/2 salt and 1/2 baking soda mix to clean the outside of my Tupperware canisters and other plastic ware. The soda cleans and the salt is the abrasive. Be sure to rinse well if you use it on the inside of your plastic ware.

    To get food stains or yellowing off plastic containers, soak and cover with a solution of automatic dishwasher detergent and very hot water.
    Soaking yellowed containers will come out like new depending on how long you soak.

    Formula: 1 tbs to 1 pint of water.

    We recently starting using 4 oz Ball canning jars for homemade pudding or applesauce to go in the cold lunches. Nothing new or fancy to buy!

    I have a plastic gas can that had fuel oil in and I would like to clean the fuel oil out to use it for putting gas in again. What is the best and easiest way to remove the fuel oil that was in it, or would I be able to use it, or should I toss it and get a new container???

    Interesting. We must all stop tossing stuff out. Reuse, recycle; we are adding to environment problems. I distinctly recall 60 years ago (short time span) walking along rivers in Africa and not seeing a piece of plastic, paper, or can. Within these last 60 years, there has been such a frightening change.

    The same here…also from Africa.
