Take some clothes to a public laundromat during the day. Undress your underwear (Female: Panties & Bra; Male: Panties & T-Shirt) inside the store and wash them with the rest of the clothes. It is up to you, how you undress.

Extreme Variation: Undress until you are naked and wash all those clothes inside the store. You can keep on your shoes while you wait for them to finish. After they finish it is up to you if you leave naked, dress the wet clothes or wait even longer by putting them into a dryer. [x3 NIP-Points]
