- Rinse eggshells thoroughly to remove any egg residue.
- Boil them in water for 10–15 minutes to kill bacteria.
- Let them dry completely, then grind into a fine powder.
This powder can be added in small amounts to smoothies, soups, or baked goods for a natural calcium boost. (Always consult a doctor before adding supplements to your diet.)
2. Boost Your Garden Naturally
The calcium and minerals from boiled eggshells also make excellent plant food. The leftover water from boiling can be cooled and poured directly onto plants as a natural fertilizer. It helps strengthen cell walls, improve soil quality, and prevent calcium deficiencies that cause problems like blossom-end rot in tomatoes and peppers.
3. Eco-Friendly Cleaning Solution
Once boiled, crushed eggshells can also serve as a gentle abrasive cleaner. Mix them with a bit of soapy water to scrub pots, pans, or sinks. The rough texture helps remove tough stains without scratching surfaces — a free alternative to store-bought scrubbing products.
5. Reduces Household Waste
By boiling and reusing eggshells, you cut down on kitchen waste and save money on fertilizer, cleaning supplies, and supplements — all while helping the environment.
