If you’re a plant lover like myself, you may have found yourself wondering when or how to go about cleaning terracotta pots. Don’t get me wrong, I love the look of a well aged patina on my terracotta, but there is a time and place for it. The patina coveted by so many will eventually build up over time. Because terracotta is composed of clay and is porous in nature, there’s plenty of room for algae and salts to build up in it’s many microscopic crevices.
