Remove any residual cleaning agents. Residual cleaning
agents will hinder the non-stick qualities of PerfectClean
surfaces.
The following cause lasting damage to the surface
structure and reduce the non-stick effect and must not be
used on PerfectClean surfaces:
– abrasive cleaning agents, e.g. powder cleaners and cream
cleaners,
– cleaning agents for ceramic cooktops,
– ceramic and stainless steel cleaners,
– steel wool or metal scourers,
– abrasive sponges, e.g. pot scourers or sponges which
have been previously used with abrasive cleaning agents,
– oven spray in a hot oven compartment or left on for too
long,
– cleaning in a dishwasher,
– selective cleaning with mechanical cleaning agents.
