Its just my sons clothes. I do wash his all by themselves and have for a while now just cause he is a teenage boy and well they can stink sometimes. I wash my hubbys clothes alone too because he gets grease from work all over the place I wash mine and my daughters together My sons clothes are the only ones that smell musty. Like they were damp and not allowed to dry properly. as the weeks pass they get worse and worse. I have tried washing them with borax.. no luck white vinegar.... no luck oxy clean.. no luck I thought it may be my washer but no one elses clothes smell like this. I have started breaking up the loads as I dry, the harder stuff, the stuff that is most likely to stay damp after everything else is dry like jeans and heavy towels all go on the line now and at the end of the day I will throw them in the dryer for 10 min to make them less stiff and to make sure waist bands are dry he showers daily, with soap I have cleaned my washer with one of those washer packs you throw in and run a cycle. My washer is a front loader. any other suggestions?
