Command adhesive is easy to use. To apply, clean the surface with isopropyl rubbing alcohol. Apply the adhesive strip to the back of the hook or clip. Press firmly to the surface for 30 seconds. Wait one hour before using. Removing the adhesive is even easier. Simply slide the hook cover up, grab the tab and slowly stretch it straight down against the wall. When used properly, only the adhesive comes off - the paint, plaster or other material stays put. And because it removes cleanly, the adhesive doesn't leave any sticky or oily residue behind. With replacement strips the product can be used over and over again.
