Anyone else experience this?

My 14 month old DD still doesn't smell clean down there after her morning diaper change. I'll use a few wipes or so to clean visible mess up, then go over once with just for a good measure. Could our hippie, scent/everything free wipes just not be doing the trick? Or should we go up a size for night time? I really don't feel like sticking her in the tub for a cleanup every morning, but can't stand her not smelling fresh either.
