Are there any materials CitriSurf is not compatible with?
CitriSurf will cause damage to the surfaces of concrete, carbon steel, zinc, and galvanized steel. Avoid exposure of these materials to CitriSurf and rinse immediately if there is an inadvertent spill onto these materials. CitriSurf can be used to clean carbon steel surfaces if care is taken to avoid overexposure, we recommend extra dilution and room temperature operation. PVC pipe and fittings made from copper, brass, or bronze are not recommended for long term use with CitriSurf.
