End-of-season bee suit and glove wash — getting alarm pheromone and propolis out without wrecking the veil or zipper

Central Texas, fourth year, twelve colonies. My suit has reached the point where I put it on and the bees are angry before I've opened a box. It's absorbed a season of stings around the wrists and ankles and I'm pretty sure it smells of alarm pheromone to them. My leather gloves are stiff, black with propolis, and frankly disgusting. Season's winding down — well, as much as it does here — so I want to do a proper reset. Questions. Machine wash the suit, and if so, hot or cold, and does detergent actually get the pheromone out? Do I unzip the veil first, or does the mesh survive a machine? Any zipper care — mine are getting gritty with propolis. And propolis stains: I've heard freezer-and-flake, I've heard rubbing alcohol, and I've heard just live with it. Finally: is it time to give up on leather gloves entirely and go nitrile?
