To evaluate supplied cleaners for bathroom soil removal on fiberglass.
Date Run:
02/14/2003
Experiment Procedure:
Four supplied cleaning products were diluted to vendor recommended concentrations for bathroom cleaning. Each product was diluted with DI water. Twelve preweighed fiberglass 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. Photographs were taken.
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 and a second set of photographs were taken. Efficiencies were calculated and recorded.
Trial Results:
All four products were successful in removing SSL Soil 1 from fiberglass coupons. Table 1 lists the amount of soil applied and removed. Table 1. Soil Application and Removal
