ca duster is fine under light dust. don't apply pressure and you willbe fine. i have used the ca duster for years now, heck, just got done doing my evening wipe with it. of course it will streak at first. it has paraffin wax in it, that is why they say you need to break it in. so the first few times, it will streak but after dusting, give it a quick qd and your good. after it's broke in, it's an awesome product.
some don't believe in it but i have thoroughly tested this duster forswirls etc.and if used right, you can't go wrong.
