Normally, when cooking, we crack an egg and throw the shell straight into the bin. However, not only is this product versatile in cooking, thanks to the countless ways it can be prepared, but its shell can also have more uses than we think. And that makes perfect sense, because this supposed waste can become a very useful resource at home.
Homemade calcium-rich fertiliser
The first application is for those who have plants at home. Simply collect some clean peelings, cover them with cold water and bring them to the boil. Once the water has cooled, it will be saturated with calcium, making it a homemade fertiliser that helps strengthen roots and improve plant growth.
How to sharpen knives
The second trick uses dried peelings. After passing them through a food processor until they become a fine powder, this granulate acts as a mild abrasive, capable of sharpening the processor’s own knives or other kitchen utensils. It is a simple method that extends the life of utensils without the need for special products.
An effective way to clean dirty pans
This same powder can also be used as a household cleaner. By mixing it with a small amount of detergent and applying it to a sponge, you can effectively remove the dark stains that usually remain on the bottom of some pans.
According to Simon, with a little effort, ‘everything is perfect’ and objects look much cleaner.
