The best way to release odour is to wash garments in hot water, Blakely says, but there are some downsides to that, as it's not the most environmentally-friendly choice. "Hot water can also damage other desirable aspects of a garment, such as moisture management, colour retention, and durability," he adds. You should follow the wash instructions (typically, wash cold, tumble-dry low) that come with your specific garment to ensure they last long. But, "a good hot wash occasionally will help rid a garment of any tenacious sebum, without causing excessive garment life or environmental issues," he says.
