"Clean if you wash every day" is a mistake!
Even if you wash your clothes just because you sweat, it doesn't mean that the odor-causing bacteria are removed. Bacteria will not be removed unless the clothes are washed in hot water above 73°C.
And the bacteria that are not removed will increase year by year. but! Polygiene StayFresh™️ treatment keeps sweat-causing bacteria from growing and keeps you clean.
