Part of the typical pre-season lacrosse prep is pulling out equipment, checking everything over, and giving it a good cleaning. If you plan on applying decals or a lacrosse helmet wrap this season, it is especially important to start with a clean helmet. Last seasons, dirt, sweat, and body oil can all act as a barrier between the helmet and the adhesive of the decals. These contaminants reduce the stickiness and make the decals more likely to peel back at the edges as the season progresses.
