  • the remaining ingredients are combined with yet another aliquot of water and this is added to the hydroxyethyl cellulose/EDTA mixture with stirring to afford the cleaning composition.
  • Test Method for Soap Scum - the test method is according to ASTM D5343-06 (Standard Guide for Evaluating Cleaning Performance of Ceramic Tile Cleaners).
  • White ceramic tiles are soiled with composite soil composed of two separate preblends.
  • One preblend consists of a mixture of synthetic sebum, metal stearates, carbon black and dirt.
  • the second preblend is a predissolved sodium stearate.
  • Soil is applied using a painting pad applicator.
  • the soiled substrate is scrubbed with a fine-celled sponge, to which the detergent system being tested has been applied.
  • a standard initial reflectance reading using a photovolt reflectometer is recommended for use to ensure application uniformity, minimum tile variability, and optimum sensitivity.
  • the percentage of cleaning efficacy of the test cleaner is calculated using the formula:
  • % cleaning efficacy (Rc-Rs) / (Ro- Rs) * 100 where: Rc is cleaned reflectance, Ro is original reflectance, and
  • Rs is soiled reflectance.
  • Test Method for Urine Scale - white ceramic glazed wall tiles (10 cm by 10 cm) and scrap iron are steeped in urine for more than one month at room temperature. Rust and urine scale deposit on the surface of ceramic tiles. Remove the soiled tiles from the urine and allow to dry overnight prior to testing. Fine pore cellulose sponges (4.5 cm by 4.5 cm) with uniform thickness and surfaces are dried at 5O 0 C. Four (4) grams of cleaner is applied to one face of the sponge with a plastic disposable pipette, covering the face as completely as possible.
  • the treated sponges are placed on a scrubbing apparatus (available from the Paul N. Gardner Co., Gardner Model AG-8100).
  • the scrubbing apparatus has settings for cycles of passing the sponge over the soiled tile with a consistent applied pressure. After the cycles are completed, a trained panelist can evaluate the cleaning efficacy by visual inspection of the tile.

  • inventive composition proceeds against conventional wisdom that the pH must be low to be effective.
  • inventive composition is more versatile (i.e., multi-purpose) while simultaneously being less irritating to users. It is understood that the present invention is not limited to the embodiments specifically disclosed and exemplified herein. Various modifications of the invention will be apparent to those skilled in the art. Such changes and modifications may be made without departing from the scope of the appended claims.
