Why does tomato sauce stain plastic containers

Tupperware discolored - that must be done

Prevent

If you've grappled with the discoloration problem before, you'll learn to appreciate the preventative measures. With fresh carrots, for example, a little bread or baking paper that you put in the can will help.

If you want to freeze tomato soup or sauce, you can use a freezer bag to put the cold sauce in. Then put the freezer bag in the can. However, the discoloration of the can is basically not a problem, because it is only a visual impairment.

  • Place sandwich paper or baking paper in the tin
  • Cling film
  • freeze bag

Slight discoloration in the plastic

With kitchen paper and a little cooking oil, you can rub off a lot of slight discolouration. Then the can is rinsed well and rubbed with a little lemon juice. Whenever you put cooking oil directly on a plastic surface, it should be neutralized with lemon afterwards. Otherwise the can will start to smell of rancid oil.

Home remedies for discoloration

A home remedy is always the best choice, especially with plastic jars from Tupperware and other manufacturers. You should never approach these products with harsh chemical cleaners.

  • Cooking oil
  • baking powder
  • sunlight

Stronger discoloration

This is where the baking powder is used again, which so often helps with cleaning in the household. Fill the Tupperware box almost to the brim with hot water and then stir some baking soda into the water. Leave the baking powder in the can for about half an hour and then wash the Tupperware thoroughly. If that is not enough, you can repeat this process again.

Do you know how beautifully the sun bleaches your hair? Exactly the same thing happens with a discolored Tupperware jar if you place it in the sun. This is probably the gentlest way to restore a stained can to its original state. Under no circumstances should you use bleach or cleaning agents that contain chlorine.
