The dust gods are strong even away from Black Rock City. I wasn't able to get my hands on an air compressor, and Operation Dust Removal Spray was met with pure, unadulterated failure. I'm assuming the product works better on keyboards and things than playa dust embedded in duffel bags, or they'd never sell! I switched to Plan B, which turned out to be hosing down all the bags and leaving them on the lawn to dry. It seems that this will work out, dust gods willing. Progress was made on the surface of my air mattress, but its still quite a mess. I'm not really sure what the best way to go about cleaning up the mattress or my sleeping bag would be, so any advice would be very much appreciated. Keep it mind that sadly, it looks like I will not have an air compressor at my disposal.
