white mould growing on terracotta pot

[westongutmann]

hello,
i bought a terracota pot a few weeks ago, and since day 1 i noticed a small darker patch on on side of the pot, as if it was wet but it wasn't. When I tried to wipe it off, the wet patch over the dark spot made the spot look even darker. White bits started to appear around the dark patch, as if it was mold or something. I've seen photos of other peoples' white spots on their pots and theirs look a bit more fuzzy and widespread, whereas mine is localised to one area, and I've wiped it off many times but it keeps growing back? I will insert a photo when it next reappears as I've just wiped it off. I even used bleach, and hand sanitiser lol, and then just plain water. none work! HELP!
the plant inside is a monstera plant and I have not been overwatering it.

Clay pots are porous and what you have is most likely mineral deposits from your water seeping through a pinhole in the pot. It is not dangerous to the plant. You can wipe it off with vinegar, but it's going to reappear. It's just a thing that happens with clay pots. If you find it unattractive get a plastic or glazed pot to put your plant in.
