I'm probably the oddball, but I HATE feeling dirty and will do almost anything to not wear something already used. On the road, you can use a small plastic container and add water, a small bit of soap, item of clothing, and shake a lot. Repeat with clean water to rinse (obviously, dispose of the soapy water in a proper manner). If in a hotel, use the sink. It didn't matter where we were, I always found some way to wash my clothes and my body. It might have involved a small tap in a park (freezing my wazoo) or a quick rinse in the sink of a restaurant (getting my hair clean involved a lot of gymnastics), but I'll do whateve I can to stay clean. You'll be surprised at how creative you'll get--very, very quickly.
