ABSTRACT:
A method to prevent deposits on a ceramic surface comprising: (1) pretreating the surface by applying an aqueous solution containing from about 200 ppm to about 1000 ppm by weight of an amphoteric fluorosurfactant, and (2) periodically applying an aqueous maintenance solution comprising from about 1 ppm to about 200 ppm of at least one of an amphoteric or cationic fluorosurfactant or a mixture thereof, from about 5 ppm to about 100 ppm of a sequestering acid, and from about 2.5 ppm to about 200 ppm of a quaternary ammonium biocide compound, wherein all concentrations are by weight of aqueous solution is disclosed.
