. Every tour I've been on washing machines were abundant.. What's the problem.. Usually camp sites offer laundry facilities.. When I've had no access to laundry facilities, i've rung my bike clothes out by hand.. But, the problem with bike clothes. Lycra might dry fairly fast, but it seems the chamois in bike shorts does not..
When on a tour, I'm biking 75% of my free time, streets clothes takes a long time to get smelly.. Usually one set of street clothes will get me through several days of riding..
