These moldy white things keep appearing on this plant and I don’t know what to do 😭

This has been going on for several months and I have tried to wipe them away hoping that they won’t come back but to no avail. It’s the only plant in my collection that seems to attract this fungus thing, which is a good thing, but I’d love to find a long term deterrent. Any help would be appreciated!

I water once every three weeks and they get pretty consistently indirect sunlight, btw.
