White mold on terracotta pot exterior

[estación seca]

Lock your boyfriend and your Masdevallia in your trunk for an hour. When you open it up, which is more happy to see you?

This "mold" is normal in terracota/clay pots.
At least I've always have seen this.

For what it's worth, the same thing happens to me regularly. I just wipe it off with a sponge. I have chemical and mold allergies and it doesn't bother me in the slightest. Estacion probably has a handle on the chemical cause of it but, I use water from my PUR filter so (according to PUR) it is pretty clean. Something else sI use a lot of with good results is Lysol Power and Free spray. It is Hydrogen peroxide with a cleaner in it. Back in the day, when I had the nursery running, I used a very pricey product called Zerotol. It was a high percentage peroxide and it worked very, very well. So does Lysol at a much cheaper price. (And if you are messy, it doesn't bleach your clothes).
