Yellowed plastic trays, the foolproof method to degrease them in just a few seconds | July 30, 2024

Plastic trays often turn yellow, but there is a surefire way to make them look new again. Here’s how to do it.

Plastic containers are very versatile containers, useful for workers and students who have to take their lunch with them. But not only that, they are also often used to store some already cooked foods such as stew or vegetables.

However, they get dirty very easily and yellowish marks form on the inside despite frequent washing. This happens precisely because of the fats contained in food. However, there is a quick method to remove these marks and make the containers look like new again. Here are some remedies.

Yellowed trays: how to make them look like new again

What you need to do is  take the yellowish container and pour some absorbent paper into it with a little liquid dish soap and warm water.  Then you have to close the container and shake it well. Once this step is done, open the container and tear the sheet of absorbent paper into pieces and then shake it again.

This process will allow the absorbent paper to absorb all the water. After about 60 seconds, you should remove all the absorbent paper and pour the remaining liquid down the drain. Then rinse the container well and it will be as good as new without the yellow marks that are so unsightly.

Remedies for yellowing plastic

After a certain amount of time, plastic tends to turn yellow due to frequent use. The causes can be substances present in the air such as cigarette smoke or exposure to the sun. In fact, it is very likely that garden furniture will change colour over time.

However, it is possible to use specific products to whiten plastic  . An example is a mixture of  bleach  and  baking soda  with cold water. Rub the yellowed part with a well-wrung abrasive sponge and leave it to act for about 10 minutes before rinsing. Repeat the operation several times until you get a good result. It takes a lot of patience.

However, if the objects to be cleaned are smaller, they can be immersed directly in a container filled with water with two measuring spoons of  hydrogen peroxide  after having previously washed them with liquid dish soap. Leave to soak for a few hours and then rinse and let dry in the open air, but not in direct sunlight.

There is another option for plastic garden furniture  , such as sofas, tables and chairs. These items are usually white and give that extra touch to the garden, but precisely because they are outdoors they tend to wear out much more quickly.
