Now, if you have a nice storage, and only need to wash a pair of panties, or a bra, or a wig maybe, one could potentially find a single-occupancy toilet and hand-wash panties in the sink, then bring them to your storage and let them dry naturally. And if you don't have a storage, but have a car, you could've try to get stuff dry in the trunk while the car is parked.., Not the best proposition - but sometimes one need to be inventive
Although for a wig, I'd go to wig-selling salon, some of them offer services to wash wigs.
