I am using mostly proraps and have one Tootleshells which used to be my favorite and now it seems they are all leaking. I only wash with Charlies soap and line dry. I did put them in the dryer a couple of times in the beginning to seal the pul. I also have 2 brand new VB AIO's that leak too. Is there some special washing that I have to do?? We were doing great for the first 5 weeks and now I am lost. Thanks a lot.
