Technical fabrics have denser weave that makes them superior in wicking. Unfortunately, it also provides safe harbor for bacteria that conventional washing can not remove.

Time for chemical warfare! I wash my commuter clothes - regular jersey, yoga bra and padded shorts - together with family undies using ALL-Oxy, unscented.

From time to time I treat the entire load to a second wash cycle with either Oxy-Clean or Borax. Both are good in killing bacteria. This treatment requires extra rinse cycle due to high pH of both Borax and Oxy-Clean.

Good luck and welcome to the forum!
