Trial Number 2

Trial Purpose:

To evaluate three supplied products for bathroom cleaning

Date Run:

10/30/2013

Experiment Procedure:

The supplied cleaning products were used at the supplied concentrations. Preweighed chrome, ceramic and fiberglass, 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 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 Wypall L30 reinforced wipe was attached to the cleaning sled and soaked with 1 spray of cleaning solutions. Each coupon was sprayed 1 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 recorded and efficiencies were calculated and recorded.

ChemistriesEvaluated: Toucan Cleaner (1 g salt/1.5L); Proforce Bath & Tile; Lysol Bathroom

Trial Results:

Free Chlorine level was measured using test strips and recorded to be 50 ppm. The pH of the solution was between 8 and 9.
All three products worked well on the bathroom soap scum using manual cleaning. The Pro-Force product had the highest overall average but the Toucan solution was nearly the identical. The table lists the amount of soil added, the amount remaining and the calculated efficiency for each coupon cleaned.

Success Rating:

Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined.

Conclusion:

All of the products were effective at removing more than 88% of the bathroom soil from the surfaces using manual wiping. Proforce exhibited the highest levels of cleaning while Lysol Bathroom exhibited the lowest.
