The package contains 10 sheets and sells at Quilter's Haven for $3.95. I had an iron that had come in contact with the wrong side of some fusible web (and had some normal build up on it as well - OK a lot of build up) -- it was in serious need of cleaning - so I opened the package and took out what looked like a dryer sheet. The package says to heat the iron on high for one minute, put the sheet of iron clean on a paper towel (I used a scrap of muslin) and wipe the base of your iron over the IRON CLEAN sheet until the residue was removed. I was skeptical at first - then totally amazed. It worked and it worked wonderfully -the bottom of my iron shined like new. All I did was run my iron over this sheet a couple of times. No burnt fingers! I was really pleased at how well it worked for me. I would definitely recommend trying it -- you will find it on the notions wall at Quilter's Haven.
