We recommend wearing clean gloves or wash hands often when handling Brutal tiles. The perimeter is cut with a trim press, which leaves a somewhat sharp edge and can result in a cut. Handle them gently, holding near the edges to avoid causing creases in the plastic. Excessive handling may make the edges not sit completely flush. Unlike mineral fiber ceiling tiles, Brutal Ceiling tiles are anti-bacterial and non-porous. The surface can pick up skin oils and particulates if not careful, especially the matte side. For a factory-fresh finish, Brutal tiles may be cleaned with isopropyl alcohol or cleaners using naphtha (Goo Gone). Regular surface cleaners may not completely dissolve skin oils so you may need to experiment. The use of a hand broom will be necessary as the PVC material attracts dust and dirt through static attraction.
