Many people put ketchup on the doorknob. Here’s why they do this.
On our tables, we often find foods that come directly from cultures other than Italian and that, although not entirely healthy, have become true standards of our dinners and lunches.
One of them, derived directly from American culture and that has delighted the palates of diners, especially teenagers and children, for many years is ketchup, which can be found in tubes or jars.
Ketchup: that’s why so many people put it on their doorknobs
This food is nothing more than a sweet and sour sauce that is usually used to accompany French fries or other fast food products such as hamburgers or other fried products.
Originally its origin is Asian and derived from Malay cuisine and the recipe was completely different from the one we know today because it was based on fish and even today in Malay cuisine we find ketchups that do not involve the use of tomatoes .
In the recipe we know today, it landed in the United States in the 18th century when some cooks adapted the original recipe with the use of tomato, which is why today it is called tomato ketchup, to differentiate it from the others.

Precisely because of the invention of ketchup as we know it today, the birth of this product is attributed to the USA , whose most widespread recipe was created by Heinz, whose company still produces it in large quantities today.
Made with tomatoes, vinegar, spices and sugar, it can sometimes contain preservatives that, although harmless, should be taken with caution as they could cause long-term problems.
The homemade method
Although it is appreciated as a sauce and is still one of the most widespread with mayonnaise today, not everyone knows that this ingredient is a true ally for the home and especially for door handles .
In our homes, in fact, there are wooden door handles dating back about twenty years and made of brass and often tend to darken and get dirty over time.
When removing the screws, you should take these handles and place them inside a saucer, then cover everything with tomato sauce and let it sit for a few minutes before continuing.

Then we take a sponge with detergent and rub vigorously and we will see how, the ketchup will have done its job and all the dirt and blackness will have disappeared from our door handles.
In fact, the composition of ketchup and the strong acidity that tomato and vinegar give it tend to eliminate stubborn dirt that forms on brass and can therefore be useful for this purpose.
In this way, not only will we have an ingredient that can add flavor to our dishes, but we will have saved on products to degrease our sleeves, which will be cleaned naturally.
