i do agree that someone say, if you can hand wash your pantry, why still need to put into washing machine?
sometimes, I will hang it to day immediately but most of the time, I worried not too clean so I put into washing machine and double wash again.
"normal clothes wun smell as much as underwear.."..Gosh... you mean your panty or hubby brief so smelly that washing detergent can't get rid of them? or they are even more smelly than your prespiration? If that is the case, you better wash separately or put on panty liners 24/7.
i still think if we put on panty liners, we don't even have such problem.
