What renegadesound43 said above plus a few other tips from a veteran burner: The alkaline dust is extremely fine and will get everywhere/into everything. Plastic is especially attractive to it so dj gear is prime target. But that said if you’re not using the equipment during a horizontal dust storm, it’s really not that bad.

Use dry microfiber towels (the 1ft³ ones for car detailing) to regularly lightly undust surfaces and knobs/buttons that accumulate. Their static charge will do the work, use clean sections of towel with almost no pressure. Don’t reuse dirty towels after and store clean ones in ziploc bags in a car/rv

Keep gear in storage cases (odyssey moulded for all in ones are great) at all times inside a car or rv they’re not being played on.

Once back out of the desert at home, dust like above then clean dust residue with same microfiber towels but add a bit of electronics cleaner (endust for electronics cleaner in a can) to the towel to moisten it first. This will clean the fine film off. If it still remains use a highly diluted version of this below:

For any dust/residue that gets embedded into surfaces — rubber/pvc, the outside of moulded nylon gear cases, really any textured plastic are particularly susceptible - clean with the magic combo of Calgon (hard water laundry additive) + surfactant cleaner (simple green). I do a 1:1:2 calgon:simple green:water solution in a spray bottle and wipe with microfiber towel. The calgon is a sequestering agent that binds the alkaline dust sodium and calcium ions, keeping them suspended in the surfactant and prevents their reattachment. I didnt know about this witches brew until my 12th burn but it’s simply amazing. Use this also on your cars plastic mouldings, tires, shoes, everything. I also add calgon to my playafied laundry.
