If you have some smelly sports gear, try this to get rid of those smells.
Its a good idea to wash sports gear in cold or warm water as hot water can set in smells.
If you can, hang out sports gear once you have worn it rather than let it sit for a long time in a laundry bag or plastic bag.
If your gym clothes are particularly smelly try putting them in the freezer for a while before you pre-wash them (in a sealed plastic bag), to kill the smells and bacteria.
