I recently switched to cloth diapers, & my daughter has sensitive skin so i switched detergents to 'all' free & clear. i just read somewhere that the free & clear detegents leave build-up on cd's. I had been noticing my clothes feeling like there was some sort of sticky residue on them lately, & I have aslo had a problem with stains not coming out that I never had before. i thought maybe it was from switching to vinegar from fabric softener but now i'm not sure. i also have hard water & i've heard that can cause problems. (but my clothes felt fine before switching to vinegar & all detergent) anyone have suggestions? would trader joe's 'next to godliness' detergent be ok? that doesn't have fragrance but it's not called a 'free & clear'. if I have a chioce between liquid or powder, is one better than the other?
