To evaluate supplied product for bathroom cleaning applications.
Date Run:
02/07/2006
Experiment Procedure:
The supplied cleaning product was diluted to vendor recommended concentrations for bathroom cleaning using DI water (10%). Six preweighed fiberglass, six ceramic and six chrome coupons were coated with SSL Soil 1 (Bathroom soap scum: Vaseline Dry Skin Lotion 21.4%, Dial Clean Rinsing Body Wash 14.3%, Market Basket Shampoo & Conditioner (Pert)28.6%, Soft Soap Natural Liquid hand soap 21.4%, Coast Deodorant bar soap 7.2% and Water 7.1%) using a hand held swab and allowed to dry for 24 hours at room temperature. The contaminated coupons were weighed again to determine the amount of soil added.
Three coupons were placed into a Gardner Straight Line Washability unit. A Professional Painter's Rag was attached to the cleaning sled and soaked with 5-7 sprays of cleaning solutions. Each coupon was sprayed 7-10 times with the same cleaning solution. The cleaning unit was run for 20 cycles (~33 seconds). At the end of the cleaning, coupons were wiped once with a dry paper towel. Final weights were recorded, efficiencies were calculated and recorded.
Trial Results:
The supplied product was effective on two of the three substrates for the bathroom soil used in this trial. The table below lists the amount of soil added, remaining and efficiency for each substrate. A comparison on one soil for water cleaning was also conducted for comparative purposes.
