Review on 🚗 The Ultimate Car Cleaning Essential: The Original California Car Duster - 2 Pack by Greg Cunningham

Dusts well but leaves a horrible oily residue instead. I saw a comment from another customer about newspaper pretreatment, so I figured there might be pretreatment instructions (as tedious as it is, at least information) but there weren't any. So I contacted the seller when I needed to do something and the seller apologized and told me to return it. I tried it with a second one just to be on the safe side, with the same result. I gave it two stars for good customer service on returns, but I cannot recommend this product.
