I love Command hooks, they are very handy. However, after I put away my Christmas decorations last year and while I was taking my Command hooks off the wall, only 1 out of 4 of them came off properly. The tab/strip thing that you pull came off of 3 of them while I was pulling.
So, those 3 Command strips hung there for about 10 months until last month while cleaning and packing for a big move for our family, I decided they needed to come off. And they did. All I needed was:
*A Blow-dryer
and
*Dental Floss
Put the dental floss between the hook and wall, on top. Hold blow-dryer to it, you'll heat up the tab part. Slowly pull the floss down while blow drying. Then BAM!!! No more command hook stuck to the wall. Easy-peasy.
