Clean Your Pots with Vinegar

Terra cotta pots heavily stained with calcium.

Frustrated by the endless scraping needed to remove stubborn calcium deposits from flowerpots? There is a much simpler solution: a good soak in vinegar.

Calcium is alkaline, vinegar is acid: they’re essentially chemical opposites. So if you soak a pot in vinegar, it will simply dissolve the calcium carbonate deposit.

The Method

20151113CJust soak your pots in a solution of one part white vinegar to 4 or 5 parts water and one teaspoon of dishwashing liquid for at least 1 hour before cleaning. Then just remove the pot from the solution and rub it lightly with a damp cloth. The stain should come off with little effort and the soap will have loosened dirt particles as well. If the pot is heavily coated in calcium, a 24-hour soaking may be required.

Finally, just rinse the pot with clear water and you’ll have a perfectly clean pot ready for reuse.

Note that anything acid will also do the job, including products like CLR cleaner, but vinegar is cheaper, likely to already be in your kitchen cupboard, environmentally friendly, and won’t irritate your skin.
