Have you ever spilled tomato sauce on a plastic surface, only to find that the stain just won’t come off? 

Tomato sauce can be particularly tough to remove from plastic, but with a little know-how, you can get rid of those pesky stains for good. 

In this article, we’ll discuss what causes tomato sauce stains on plastic, how to remove them, and how to prevent them from happening in the first place.

Let’s begin.

What causes tomato sauce stains on plastic?

Tomato sauce contains a variety of compounds that can contribute to its staining properties on plastic. However, one of the main culprits is a pigment called lycopene. 

Lycopene is a bright red carotenoid pigment found in tomatoes and other red fruits and vegetables. When tomato sauce comes into contact with plastic, the lycopene can easily stick to the surface and cause a stain. 

The acidity of the sauce can also contribute to the staining effect. If the plastic surface is porous or has any scratches or cracks, the tomato sauce can penetrate the surface and become even more difficult to remove.

Additionally, if the sauce is hot, it can cause discoloration on some types of plastic. This is because the heat can cause a chemical reaction between the plastic and the tomato sauce, resulting in a permanent stain.

How to remove tomato sauce stains from plastic?

If you’ve already got a tomato sauce stain on your plastic surface, don’t despair! There are several methods you can use to remove the stain:

  1. Soap and water: Mix a few drops of dish soap with warm water and use a sponge or cloth to scrub the stain. This method is best for mild stains.
  2. Vinegar: Mix equal parts of white vinegar and water and use a cloth to rub the stain. Vinegar is a natural acid that can help dissolve the tomato sauce and lift the stain.
  3. Baking soda: Mix baking soda with a small amount of water to form a paste, then apply it to the stain and scrub with a sponge. Baking soda is mildly abrasive, so it can help scrub away the stain.
  4. Other household cleaners: If the above methods don’t work, you can also try using rubbing alcohol, hydrogen peroxide, or other commercial cleaning solutions to remove tomato sauce stains from plastic.

Whichever method you choose, be sure to test it on a small, inconspicuous area first to make sure it doesn’t damage the plastic.

How to prevent tomato sauce stains on plastic?

Prevention is always better than cure, so here are some tips to minimize the risk of tomato sauce stains on plastic:

  1. Use a protective cover: If you’re cooking with tomato sauce, use a cover or lid to prevent the sauce from splattering onto nearby plastic surfaces. This is especially important if you’re cooking with high heat.
  2. Don’t reheat tomato sauce in plastic containers: The heat from the sauce can cause discoloration on some types of plastic, so it’s better to use a glass or ceramic dish to reheat the sauce. Alternatively, you can transfer the sauce to a microwave-safe container before reheating it.


In conclusion, tomato sauce stains on plastic can be a real hassle, but with the right techniques, you can get rid of them. 

Whether you’re dealing with a fresh stain or an old one, there are several methods you can use to remove tomato sauce from plastic. 

And by following the prevention tips we’ve outlined in this article, you can minimize the risk of tomato sauce stains happening in the first place.
