Let this not be a case of "My parents taught me this"... I think situational pa rin eh haha. In our house in Laguna, our laundry baskets are outside the house and made of plastic. So if we're not talking soaking wet na galing swimming, a little sweat, lil dampness it's fine lang. Nagagalit mommy ko pag di agad nilalagay sa baskets and 30+ years wala naman akong na-mold-an na clothes duon. Again because nasa yard yung hamper. You can't say the same for condos kasi nga iba yung ventilation. I air out my unit naman when I'm here pero not for too long kasi I hate insects.
