1 Mellow your coffee
If you prefer a slightly gentler wake-up drink in the morning, you can add a piece of clean eggshell to the filter bag before brewing the coffee: this will prevent the coffee from becoming bitter.
2 Fertilize plants
The shells of raw eggs contain valuable minerals. Crush them and add them to the irrigation water and leave them in for two weeks so that the substances have completely dissolved.
3 Whitening laundry
Looking for a natural alternative to bleach? Simply put a few crushed white eggshells in a bag and wash with white clothes.
4 Clean pans
Mix crushed eggshells with a little soapy water and use to scrub encrusted pans and pots - the shell particles act as a scouring and polishing agent. But be careful: Do not use on coated pans or pots made of sensitive materials!
