Use softener. Downy works best. Try all the colours and see which smell you like the most and remember not to put too much cause the smell can be overpowering. Also, add Dettol into your load. For detergent I use liquid detergent like Breeze Goodbye Musty or Anti-Bacterial (indoor drying). Sometimes I use Dynamo with Downy. For Downy softener, I like the parfum series (black purple, black red, black pink) and the essential oil series. I don’t like powder detergent because they can leave white spots on clothes. Also, hang out to dry in the hot sun if you can.
