A mask and ventilation techniques, for example, depressurizing the cabin while you're doing the work, so otherwise the mold spurs get released in the air. Honestly, it's not a do-it-yourself job, although I know a lot of folks that have hunting cabins and that sort of thing will do it themselves. But you've got to be really careful the way you go about this because you can make it worse.
