Go to the pages with the card stock and all the colors, go to Yoyo Yellow. Order a classic Yoyo Yello pad and you'll have your StazOn cleaner.
In all truth, SU doesn't sell the cleaner because there are so many other things out there including Yoyo Yellow pads that clean the StazOn just as good if not better than the StazOn cleaner. If you need directions using the Yoyo Yellow, just let me know, I'll be more than happy to post them.
