Clean glass vases
Tips on how to clean glass vases in hard-to-reach places have been included here, e.g. with dry rice grains or crushed eggshells.
By chance, I came across another method, looking at a windlight, the z.T. filled with small pearly-colored decorative pebbles (size 6-8mm).
I filled 1-2 teaspoons into vases, added some water and shaken vigorously. Everything clean again!
Then pour into a small sieve, let it dry and reuse as often as you like.
The stones are polished and have rounded edges, so that no scratches can occur.
