How can clothes be purified from madhy (pre-seminal fluid) when its location is not precisely identified, taking into consideration travel circumstances and the inconvenience that would result from washing the garment?

Pre-seminal fluid (madhi) is impure and invalidates ablution (wudu’). What it touches of one’s clothes or body must be washed; merely sprinkling water on it is not sufficient according to the majority of scholars. If pre-seminal fluid gets on one’s clothes and its exact location is unknown, the entire garment must be washed before prayer. The fact that the garment might appear unsightly after washing does not permit praying in it while it is impure; it is possible to replace it with a pure garment.
