Wie oft Arbeitskleidung wechseln bzw waschen?

The t-shirt daily, the sweater depending on usage (in winter at dirty work daily, in summer weekly if at all). I also change the pants up to two times a week depending on the pollution, but I’ll carry them all week. In the summer I wear the short trousers for two weeks, as they are not dirty at the Hinknien ia. On the weekend everything comes together into the washing machine.
