I don't use cycle specific clothing, preferring to cycle in civvies and be mistaken for a local and have enjoyed visiting launderettes or whatever they may be called in foreign places wasserette/ waschsalon/ vaskeri/ pradelna/ tvattomat etc etc. If you can find one close to a pub it can be convenient to try out the local brew whilst dotting back and fore to check progress in the washing m/c. They provide good opportunities for discussion with fellow customers on all sorts of topics which one might wish to clarify in regard to local customs and habits. Drying was never a problem as they are usually equipped with tumble driers. I remember discussing a problem with the Dutch equivalent of zebra crossings in one launderette and asking a woman why some pedestrians did not walk across the zebra even when they could see I had ample stopping time. They probably thought you were a local was her response.
