Stretch ceilings are truly exceptional! Among the many advantages of PVC film is its antistatic effect. This prevents dust particles from adhering to the ceiling surface, which means it practically needs no cleaning. Wiping it once a year is enough (if you like everything to be spotless!).
Even if an accident happens and dirt does reach the ceiling, there is no need to look for special products. A cloth dampened with water, preferably distilled to avoid salt marks, and a cleaning solution are enough. The important thing is to avoid aggressive substances such as chlorides, acetone and persistent dyes. Window-cleaning products work very well on glossy PVC film.
