Our double-sided OXO Good Grips Microfiber Extendable Duster traps dust without the use of harsh chemicals. Extend the lightweight aluminum pole from 24 in//61cm to 52 in/132 cm to easily clean in difficult spots like under refrigerators and on top of bookshelves. Pivot the generous microfiber head 270° and lock it into place to securely dust a large area with a single swipe. Unsnap and remove the head for convenient machine washing. For best results, wash the head in cold water without fabric softener or bleach. Do not heat-dry. Replacement heads also available.
