We all know how beneficial eggs are for health. However, after making scrambled or boiled eggs, we often throw away the shells, considering them useless waste. But it is known that eggshells contain over 90% calcium carbonate and various minerals.
This calcium can serve not only as a tonic for houseplants but also significantly simplify many tasks in household cleaning and kitchen work. Therefore, next time you cook eggs, do not throw away the shells. Below are five of the most effective and practical ways to use eggshells.
Calcium-rich fertilizer for plants: The eggshells must be washed, dried in the sun, and then ground into a powder. This powder should be mixed with the soil of your houseplants, especially tomatoes, peppers, roses, and monsteras. This helps eliminate calcium deficiency in the soil and promotes fast and lush plant growth.
Sharpening blender blades: If your blender blades have become dull, place dry eggshells in the blender jar and add a little water. Turn on the blender for 1-2 minutes. Thanks to the friction of the shells, the blender blades will become sharp again, like new.
Cleaning burnt and stuck-on dishes: If there are burnt or greasy spots on a pot or frying pan, you need to roughly crush the eggshells. Mix them with a small amount of detergent or soap and use them as a scrub. The dishes will shine without any scratches.
Creating a natural pest repellent: If slugs, snails, or small insects are eating the leaves of plants in pots or in the garden, break the eggshells into pieces and scatter them around the plant stem. Due to their pointed surface, pests cannot reach the plants.
Using as a seedling tray: Slightly crush the eggshells, fill them with soil, and plant small seeds in them, such as coriander, pepper, or tomatoes. When the small plants appear, they can be transplanted into a pot, leaving the shell behind. The shell will gradually decompose in the soil, nourishing the plant.
