Alright so I've been using my meguiars duster for a couple of years now I usually dust my car off and touch it up with griots speed shine every day to every other day depending on how much I drive it. The Meguiars duster is the paraphin oiled type and while it works great (pics up dust never had any scratches) it doesn't seem to last very long. It'll work well for about 5 months and it won't be dirty or anything but the one day it'll just start streaking like crazy, as if its suddenly become over oiled. It doesn't hurt or scratch the paint but its very annoying. Does anyone know a better brand of duster (is a non-oiled ok?) or perhaps a different method?
