- HG detergent additive against unpleasant odours in sports clothing is a highly effective sport wash detergent formula that efficiently removes stench molecules that have penetrated deep into the fibres. Nasty smells in sportswear caused by perspiration during sports or because the laundry has been left too long in the sports bag, laundry basket or in the washing machine cannot be eliminated with a regular detergent alone. These nasty smells become noticeable when the clean clothes are being ironed or worn. Our sport wash detergent quickly and easily removes the sweat odour from clothing.
