I know, and it's crazy talk. I'm sure it was taken out of context (the context being unhappy customer on phone). If you could build up layers of AW, everyone here would be doing it, and we would have heard about this "cloudiness" a long time ago. Besides, I'm sure there are dozens of members who use it after every wash, which might be several times a week.
EDIT: These forums are great for disseminating knowledge, unfortunately (as in this case) they are also great for disseminating nonsense. If you don't wipe your AW clean, you're going to get a "cloudy" area of unbuffed product, I'm sure that was the implication, which is a little different than layering proper application until it's not "optically clear".
