“The Magic of Eggshell Char: A Multipurpose, Cost-Effective Household Solution”

Once the eggshells are clean, let them air dry before crushing them into small pieces and placing them in a pan or pot to roast. Roasting eggshells helps sanitize and disinfect them at high temperatures, aiding in longer preservation. Roast until the shells turn yellowish and emit a pleasant aroma.

Allow the roasted eggshells to cool, then transfer them to a grinder, preferably a dry, grain-type grinder. Since the shells are already roasted and brittle, they should easily turn into a fine powder. The finer the powder, the better. Subsequently, store the eggshell powder in an airtight container for future use.

As many may know, eggshells primarily comprise calcium carbonate and also contain protein and trace elements, offering excellent benefits for plants. Thus, you can use eggshell powder as a fertilizer for your flowers and potted plants.

Specifically, you can directly sprinkle the eggshell powder onto the soil surface. Once you water the plant, the nutrients will gradually seep into the soil and be absorbed by the roots, nourishing the plant.

Alternatively, mix the eggshell powder with the soil when repotting your plants. This method not only provides nutrients and enriches the soil but also helps aerate it, preventing soil compaction.

Additional Benefits of Eggshells

Apart from their use as a fertilizer for potted plants, eggshells offer numerous other advantages in our daily lives. For instance:

– Cleaning Thermal Flasks

Over time, thermal flasks accumulate sediment at the bottom, which, if left unattended, can affect the water quality and even our health. Since the flask’s mouth is typically narrow, cleaning it thoroughly by hand is challenging, and specialized tools are required.

If you don’t have the appropriate equipment, you can clean the flask by adding clean, crushed eggshells and a little water, tightening the lid, and shaking the flask vigorously.

Eggshells mainly consist of calcium carbonate, which, when exposed to high temperatures, releases superactivity that promotes the breakdown of sediment in the flask. Additionally, the eggshells’ constant friction against the flask’s interior effectively removes stains without scratching the surface.

After shaking for about 3-4 minutes, discard the eggshells and water, and rinse the flask thoroughly with clean water to remove any remaining residue.

– Cleaning Range Hoods

Eggshells can also be used to clean range hoods. First, prepare a disposable face mask and cut off one end with scissors. Then, take two eggshells, crush them, and place them inside the mask. Secure the mask with a string or rubber band.

Next, prepare a cleaning solution by mixing baking soda, white vinegar, a few drops of dish soap, and some hot water in a bowl. Dip the eggshell-filled mask into the solution and use it to wipe away the grease from the range hood. The grease should come off easily with a few simple swipes.

This method works because baking soda and dish soap are powerful grease-cutting agents, while white vinegar softens stubborn stains. Additionally, the eggshells in the mask increase friction, effectively removing oil residue from the range hood’s surface without scratching it.

After cleaning the range hood, use a clean cloth to wipe it down, leaving it sparkling clean.
