Refer to the cleaning guidelines in specification 609-23010.
Under certain conditions, the presence of free chlorine and other oxidants can cause premature degradation and damage to the membrane. Due to the fact that oxidative damage is beyond the warranty scope of Dow film, FilmTec recommends that users remove residual free chlorine through pre-treatment before it comes into contact with the film.
