The rig gets washed in the driveway. The gear does not. After a weekend in the Nevada desert, the riding pants, jerseys, socks, gloves and neck gaiters come home zipped into a bag with fine silt worked into every seam, and on Sunday night that bag tends to get emptied straight into the washing machine. The shop wash-down gets planned and argued over. The laundry room almost never does.
Silt is the part of the desert that behaves least like dirt. It is fine enough to hang in water, which is why it rides through a wash cycle and leaves with the drain water instead of staying in the drum. A washing machine pushes that water out fast, into a standpipe and a laundry line that see mostly lint and soap the rest of the week, not a load of gear that spent two days in a dust cloud behind a trophy truck. The rider brings the same problem into the shower. Hair, ears and the skin under a neck gaiter all hold dust, and a long rinse after the drive home sends more of it down the tub or shower drain than anyone would guess. One weekend does not matter much. A racing season of them, plus a practice day here and a trail ride there, is a different number.
Most of it can stay outside. Shake the gear out on the driveway before it gets carried inside, and turn pants and jerseys inside out so the silt falls out of the seams and pockets. A bucket rinse in the yard takes the heaviest layer off before the machine sees it, and the bucket can be emptied onto gravel rather than into a drain. Boots and boot liners can stay outside entirely. Some washers have a pump filter behind a small access panel, and the owner's manual will say whether yours does and how to clean it.
A standpipe that gurgles or overflows during the spin cycle, or a shower that drains a little slower every week, is past the shake-out stage. A rider dealing with that might look at A.A. Cassaro Plumbing in Las Vegas, a plumbing company that lists laundry line stoppages and tub and shower stoppages among its services. Live On Dirt has no arrangement with the company, and there are other plumbers in the valley who do the same work.
Race prep already runs on checklists: fuel, spares, radios, the recovery bag. Plenty of teams also do a walk-around at the trailer before the drive home, checking straps and counting tools. Adding a shake-out stop at the tailgate before the gear bag gets zipped takes two minutes at the pits and leaves most of the weekend's silt on the ground out there instead of in the laundry line at home.
