You can find a washer and drier pretty much everywhere. Most hostels have facilities for washing clothes, and hotels usually provide this as a service. And then there are laundromats of course. The only problem is what to wear while washing stuff, and of course the fact that you need to handle this quite often if you only travel with one set. This is why I always travel with one or two changes in my backpack.
