I use Febrese with heavily sweaty shirts or sweaters, you unfortunately can only wash at 30 degrees. Sprayed just before the wash and then into the washing machine. And the things come without sweat odor from the washing machine (formerly often the case, as I did not know the trick with Febrese and so I often have to wash the stuff several times, which was indeed a waste of water, and Waschpuler, excess energy.)
