Schlüter-KERDI-DRAIN-SP requires no special maintenance or care. Stainless steel surfaces exposed to the environment or aggressive substances should be cleaned periodically using a mild household cleaner.
Regular cleaning maintains the neat appearance of stainless steel and reduces the risk of corrosion.
All cleaning agents must be free of hydrochloric and hydrofluoric acid.
Avoid contact with other metals, such as regular steel, to prevent corrosion. This also includes installation tools such as trowels or steel wool, e.g. for the removal of mortar residue. We recommend the use of the stainless steel cleaning polish Schlüter-CLEAN-CP.
