Trial Number 13

Trial Purpose:

To test the efficiency of Clorox Bathroom spray on the removal of bathroom soil from ceramic, plastic, and chrome substrates.

Date Run:


Experiment Procedure:

Initial weights of each substrate (ceramic, plastic, chrome) were taken and subsequently soiled with 0.5 grams of Bathroom soil. The bathroom soil was allowed to dry for 24 hours before dirty weights of the coupons were taken. Each substrate was manually wiped using the SLW machine with the Clorox Bathroom cleaner. 2 sprays were added to each wipe and coupon. The SLW unit was used for 20 cycles. Final weights were taken an hour after coupons were cleaned.

Trial Results:

Success Rating:

Preliminary compatibility tests on substrate coupons encouraging for at least one cleaning chemistry. More in-depth laboratory testing necessary.


Overall, this product cleaned the bathroom soil with an overall removal percentage of 81%. It removed soil from the chrome substrate the best with an 88% removal rating. The product itself passes the level in which a product needs to perform as a cleaner which is above an 80% removal rating.
