A:Answer DENTAL FLOSS: Pull off a LONG length from the dispenser (about 24-30 inches). Fold in half, then half again,
Pry up a corner of the disc from the back of your phone - hopefully you can do this with your fore-finger and thumb while at the same time, hold the folded string of dental floss and slide is between the disc and the phone when you get the disc pried up a tad bit.
Slide the dental floss underneath starting at the top of bottom of the disc to the other end while at the same time, pulling straight up with the floss and edging the disc up, off the phone.
When I did this, I got half way down the disc and it just "popped" up and off the phone. All I had to do was take some eyeglass cleaner to the phone to wipe away any of the dental floss wax and all was clean and NO SCRATCHES/DAMAGE to the phone. An I think I can still use the disc again as the sticky part seems to still be in pretty good shape - just remember to stick it to a piece of waxed paper in the event you want to use it on something else - no guarantee but you can always try.
