Extendable Cob Web Duster 4 "Excellent product" Anne 29 January 2014 Delighted with this purchase. Removes webs and dust easily from difficult to reach places. There are no washing instructions so I don't know if I am able to wash it occasionally, am giving only 4 stars for this reason. A note from the team Thanks for taking the time to write your review. The duster can be washed with a mild detergent and left to dry naturally. The head does unscrew from the handle for washing.
