Trial Number 4

Trial Purpose:

To compare current tub & tile cleaners (Ecolab) with proposed new cleaners (Rochester Midland).

Date Run:

05/19/2000

Experiment Procedure:

The new products to be compared were diluted to 4 oz cleaner in one gallon of water (approximately 3% by volume) for the Rochester Midland Washroom Fixture Cleaner, 8 oz cleaner in one gallon (approx. 6.25% ) for the RM Tough Job, and 4 oz in one gallon (6.25%) for the RM glass cleaner, using DI water. The solution was put in a one quart plastic spray bottle, similar to the supplied for the current cleaning solution.
The contaminant solution was applied to the appropriate surface material, ceramic tub tiles, marble, or glass/mirror. The tiles were allowed to sit for five minutes before cleaning took place. Observations were made by SCL Staff member to determine what the baseline level of contamination looked like. After recording the sets of observations separately, the cleaning process was started. Cleaning involved spraying the tile with one spray, then wiped until clean with cloth rags. The spraying and wiping was performed by the same individual for all tiles and cleaners to ensure consistent cleaning. During the wiping, observations were made as to how easy the cleaning felt. After all tiles were cleaned, final clean observations were made by the same staff member. One tile was cleaned for each solution to be evaluated. The cleaning products were ranked according to all observation made during the entire trial.
