Still haven’t found a way to get rid of the tomato sauce stains that give plastic food containers that ugly look? Well, perhaps the time has come to try a more effective method, like the one proposed in the TikTok profile @cocinaconmimadre. Behind this account are a mother and her son, who, in addition to sharing numerous cooking tricks with her followers, explain how to leave household utensils and containers spotless.

Neither the grease from the pots and pans nor the dirt impregnated on the cloths can resist them. And the tomato sauce embedded in the container is not spared either. The trick is to put a paper napkin in the container with a little bit of dish soap. Then it is filled with hot tap water, closed with the lid and shaken for a few seconds. And ready! Container stains disappear instantly and almost effortlessly.

If the spots are very embedded, you can try one of the methods shared by the technologist and dietitian-nutritionist Beatriz Robles in Safe eating by eating everything (Planet). The first is as simple as leaving the container for several hours with hot water and a splash of vinegar. Another option is to use a mixture of water and baking soda, and leave it on overnight. Finally, the expert advises using food bleach with water.

However, the best thing to keep the tuppers like the first day is to take care of them. Food safety experts say that you always have to clean them after each use. That is, do not wait too long to do it.

The dishwasher is the best way to do it, but it is important that we look at whether the container can be washed in this appliance, information that is usually printed in the form of icons on the surface of the container. On the other hand, using scouring pads for washing is not a good idea, because it can crack the container.

Nor should we ignore the signs that the time has come for our lunch boxes to retire. When it has cracks, scratches, loses consistency, or acquires the color of food, the time has come to change it. Same thing if it starts to smell bad.
