Hot Tools Styling Iron Cleaner is a safe, non-toxic spray that will keep your flat iron in tip top shape and ready for the next use. Over time, styling products used on your hair causes build up on your flat irons and curling irons. This build up leads to excess stickiness on the plate surface, and results in poor styling results. The gummy residue on the plates can also cause damaging stress to your hair by pulling and snagging the strands, causing split ends and breakage. Styling irons are meant to glide through your hair smoothly, so it's very important to make sure your iron is clean before each and every use.
