Toilet bowl cleaning apparatus and methods

A method for cleaning a toilet bowl, comprising:

• providing an intermittent flow of water from a water line to a toilet bowl with each flush of the toilet bowl, and
• providing a water-soluble compound to intercept a substantial portion of the flow of water, said water-soluble compound thereby being released into the toilet bowl with the water from each flush to inhibit formation of mineral deposits on the surfaces of the toilet bowl and/or drainage pipes.

A toilet bowl cleaner unit installable under the rim of a toilet bowl comprising:

• a generally linear, resilient mounting strip having a front side and a back side, said mounting strip being bendable into a horseshoe-shape configuration for installation beneath the rim of a toilet bowl with said back side facing the bowl, said mounting strip storing energy therein when bent, said stored energy acting to exert a radial force which maintains the mounting strip in place against the toilet bowl;
• and
• an exposed, water-soluble compound positioned against the back side of said mounting strip, a dissolved portion of said compound being released into the toilet bowl with water from each flush to inhibit formation of mineral deposits on the surfaces of the toilet bowl and drainage pipes.

A disposable cleaner unit installable under the rim of a toilet bowl comprising:

• a generally linear, resilient mounting strip having a front side and a back side, said mounting strip being bendable into a horseshoe-shape configuration for installation beneath the rim of a toilet bowl with said back side facing the bowl, said mounting strip storing energy therein when bent, said stored energy acting to exert a radial force against the toilet bowl which maintains the mounting strip in place;
• and
• multiple supplies of an exposed, bleach in solid form secured to the back side of said mounting strip along a major portion of its length, a dissolved portion of said compound being released into the toilet bowl with water from each flush to inhibit formation of mineral deposits on the surfaces of the toilet bowl and drainage pipes.
