Why Tomato Sauce Stains Plastic Tupperware

Have you ever noticed that tomato sauce stains on plastic containers can be tough to scrub off even after washing them multiple times? This is all due to the science behind tomato sauce and how it interacts with plastic.

Tomato Sauce Stain Science

Tomato sauce contains a high level of acidity, which is what gives it its tangy taste. However, this acidity also causes it to react with chemicals in plastic containers causing discoloration and staining.

The longer the tomato sauce stays in contact with the plastic surface, the deeper and more intense the stain becomes. So, if you leave your spaghetti leftovers in a plastic Tupperware container overnight or even for a few hours, you may find yourself struggling to remove the bright red stain later.

Different Plastics Affect Stain Removal

Not all plastics are created equal when it comes to their ability to resist tomato sauce stains. Some plastics are highly porous and allow tomato sauce particles to seep into microscopic pores making them nearly impossible to clean out completely.

  • BPA-free plastics tend to be less porous than those containing BPA.
  • HDP or HDPE (high-density polyethylene) containers tend not to absorb color from acidic foods as much as many other types of plastic tubs or food storage bags like LDPE (low-density polyethylene).
  • PET plastic material such as those found in many water bottles have a higher heat tolerance but aren’t resistant against becoming stained by acidic foods like tomatoes.

To prevent stubborn tomato stains from ruining your favorite Tupperware container, avoid storing acidic foods such as spaghetti or lasagna for long periods in certain types of plastic containers.

The best way to keep your food and plastic storage containers stain-free is by washing them immediately after use. When washing, be sure to use warm soapy water and a non-abrasive scrubber. If you can’t get the stain out, try soaking in a mix of vinegar and baking soda or using stronger dishwashing detergents specifically designed for removing tough stains from plastics.

Essential Tools and Ingredients

Removing tomato sauce stains from clothing can be challenging, but having the right tools and ingredients can make the process easier. Here are some essential items you will need:


  • White Vinegar or Lemon Juice
  • Baking Soda
  • Liquid dish soap
  • Toothbrush or soft-bristled brush
  • Clean white cloth or paper towels to blot up excess liquid


  • White vinegar or lemon juice can help break down the enzymes in tomato sauce stains.
  • Baking soda has natural stain-removing properties that make it effective in removing stubborn tomato sauce stains.
  • Liquid dish soap is useful in breaking down grease and oily residues from the tomato sauce.

You may already have some of these tools and ingredients on hand, but if not, they are readily available at your local grocery store or online. When shopping for these items, be sure to look for high-quality products that are known for their stain-fighting capabilities.

In conclusion, with these essential tools and ingredients on hand, you’ll have a better chance of effectively removing tough tomato sauce stains from your clothes without damaging them.

Pre-Treatment Methods

Removing tomato sauce stains can be a real challenge, especially if you don’t take the appropriate pre-treatment steps. In fact, attempting to clean tomato sauce from clothes or upholstery without pre-treating it can actually make the stain worse.

Importance of Pre-Treating

The reason why pre-treating is so important when it comes to tomato sauce stains is that this type of stain is oil-based and acidic. This means that soaking the garment or fabric in warm water and detergent won’t work because water repels oil.

To effectively remove these types of stains, you first need to break down the oils and loosen the particles clinging on your clothing. The acidity from tomatoes often makes them quite challenging to get out of fabrics, but pre-treatment methods can make all the difference.

Effective Pre-Treatment Methods

  • Soaking: One effective way to pre-treat a tomato sauce stain is by soaking it in cold water with laundry detergent for at least 30 minutes before washing as usual. You can also use enzyme cleaners which are specifically formulated for protein & oil stains like Pet Stain Eraser Concentrate from Bissell.
  • Baking Soda: Another effective method involves creating a paste using baking soda and water. Simply mix equal parts of baking soda with warm water until it forms a thick paste-like consistency then apply directly onto the stain and let sit up to an hour (but do not let dry completely). Finally rinse with warm water.
  • Vinegar: If you have white clothes that have been stained by red pasta sauces or ketchup perhaps one could add vinegar instead of baking soda when mixing up their cleaning solution as done above.
  • Rubbing alcohol: Rubbing alcohol is another effective pre-treatment method. Dab a small amount of rubbing alcohol onto the stain using a clean cloth, let it sit for 10-15 minutes and then wash as you normally would.
  • Dish Soap: A little bit of dish soap can also work wonders in removing tomato sauce stains. Apply some dish soap to the stained area and rub it gently before washing as usual.

In conclusion, when dealing with tough tomato sauce stains always remember to first pre-treat them before washing. Using these effective methods will definitely help you in getting rid of stubborn tomato sauce stains from clothing or any fabric!
