That kind of line is usually clickbait, but there are a few real uses for boiled eggshells instead of throwing them away.
If you boil eggshells and clean them properly, you can reuse them in a few practical ways:
One common use is as a natural calcium supplement for plants. Crushed eggshells add calcium carbonate to soil, which can help reduce problems like blossom end rot in tomatoes and peppers. They break down slowly, so they’re more of a long-term soil booster than an instant fertilizer.
You can also dry and crush them into a fine powder and mix a small amount into compost. This helps balance acidity over time and enrich the compost with minerals.
Some people use crushed shells as a natural pest deterrent around plants. The sharp edges can discourage slugs and snails from crossing into garden beds, although it’s not a perfect solution and needs reapplying after rain.
A less common use is in homemade cleaning scrubs—crushed shells can act as a mild abrasive when combined with baking soda, useful for scrubbing pots and pans (though you have to grind them very finely to avoid scratches).
If you want, tell me what you saw after “say goodbye to…”, and I can decode exactly what that post was claiming and whether it’s actually true or just internet hype.
