Gardening Trick That Works: Removing White Deposits From Terra-cotta Pots

Posted by on April 15, 2014

Calciium on terracotta potsTo everyone who knows me, you may find it odd that I’m writing about how to remove the white buildup found on terra-cotta pots.

I like patina–the more the better. I tend toward the old, the tattered, and one many occasions, the trashed.  I anxiously wait for the orange of my new terra-cotta pots to become mottled with white mineral deposits. The white deposits are calcium and other minerals found in our public or well-water water, and in fertilizers. Clay wicks from the contents inside and this causes the calcium and other mineral deposits to accumulate on the outside. The white discoloration will not harm pot or plant.

For those that do not like the look, it’s easy enough to remove. Combine equal parts white vinegar, rubbing alcohol, and water in a stray bottle. Spray and scrub the pot with a brush. Your deposits will dissolve. Rinse and let your pot dry before planting.
