Abstract
The present invention is an improved liquid toilet bowl cleanser comprising a fluorosurfactant coating agent, an anionic or non-ionic cleaner and a rheology control agent together with other minor excipients. The flurosurfactant continually adheres to and coats the porcelain surface of the toilet bowl during the active life of the cleanser composition preventing the formation of toilet bowl stains and mineral deposits for a substantial period of time after manual cleaning.
