I hand/delicate wash most of my clothes.(esp nice tshirts and oxfords) it prolongs the life of your stuff 10x - never understood people that said it’s “too much” (sounds lazy to me) Sometimes you just need to hit your shirt collars and sleeves after wear or before you throw it in the washing machine. The bar and brush are both small so I can bring them with me when I travel. (Sometimes I'll just get a new bar as part of my travel checklist, it makes my luggage smell good too!) I try to keep one in my car, at the store, office, etc. Just in case of emergencies.
