Why does starch flake?
Product flaking may be caused by a number of things. One reason may be the iron setting. A wrong setting can cause product to flake. To help prevent flaking, avoid heavy applications of starch. Over saturating any area with starch sometimes causes a noticeable foam that can flake when dry. Next, you should always allow the starch to penetrate the fabric for about 10 -15 seconds before the iron touches the garment. Light applications of starch will soak into the fabric almost instantly while heavy applications will take a little longer. Lastly, shake can vigorously before each application.
