Trial Number 3

The supplied cleaning products were used at the recommended concentration. Pre-weighed ceramic, plastic and chrome coupons were coated with SSL Soil 1 (Bathroom soap scum: All-in-one shampoo and conditioner 28.6%, Dry skin lotion 21.4%, Liquid hand soap 21.4%, Liquid body wash 14.3%, Deodorant bar soap 7.2% and water 7.1%) using a handheld swab and allowed to dry for 24 hours at room temperature. The contaminated coupons were weighed again once dried to determine the amount of soil added.

Three coupons were placed into a Gardner Straight Line Washability unit. A Wypall X60 reinforced wipe was attached to the cleaning sled and soaked with 1-2 spray of cleaning solutions. Each coupon was sprayed 1-2 times with the same cleaning solution. The solution was allowed to penetrate for 30 seconds followed by cleaning in the SLW unit for 20 cycles (~33 seconds). At the end of the cleaning, coupons were wiped once with a dry paper towel. Final weights were measured, and efficiencies were calculated and recorded.

A cleaning product is considered effective when the efficiency of the product removes 85% of the soil and above. The most effective cleaning solution tested was the Tile Grout HC with an overall cleaning efficiency of 93.08%. The next best choice for overall cleaning efficiency was the H2 Orange 2 Tile cleaner with a cleaning efficiency of 89.82%.  Next up was the Neutral Floor HC cleaner which trailed behind a little at 87.71%. The least effective cleaner that was tested was the Multi-Purpose HC cleaner which had an overall cleaning effectiveness of 83.64%.
