Hi. My style would be to trim the leaf and keep an eye on it. You could use a mix of 1 teaspoon Castile soap (the liquid kind) and 1 quart water - wipe it with a Q-Tip. I’ve tried Neem, insecticidal super soap, and a bunch of other alcohol/hydrogen peroxide mixes to treat soil and succulent leaves, and find that they’re too harsh.

Here is a random picture of mold that I once treated lol.
