To test the removal of maintenance soil from aluminum, stainless steel and painted metal using industrial cleaning methods.
Preliminary compatibility tests on substrate coupons encouraging for at least one cleaning chemistry. More in-depth laboratory testing necessary.
Project Number 2
Summary:
A total of 18 coupons were obtained and used for this test. 6 coupons were used for each of the 3 cleaners. 9 coupons in total for each substrate, substrates being glass and chrome plated aluminum. The initial weights of the tiles were taken in order to use it as a standard and also determine how much soil was removed after cleaning. The coupons were then soiled with 1 gram of AATCC Carpet soil and baked in an oven at 75 degrees Celsius for 4 hours. These coupons were then removed after the 4 hours and dried over night. Dried dirty weights were then recorded. The specified cleaners were then used to test cleaning effectiveness on the chrome plated aluminum surface and the glass surface. Each set of 3 coupons (per substrate) were placed in the SLW machine and washed. Two sprays of cleaner were applied to the wypal and two sprays of cleaner was applied to each dirty coupon. The SLW cleaned for 20 swipes (down and back is 1) before removed the set and moving onto the next set of coupons. After all coupons were cleaned with their respective cleaners, they air dried for an hour before final weights were taken and recorded. Effectiveness of the cleaners was then calculated and recorded.
Test Objective:
The objective of this test is to evaluate the supplied cleaners and their effectiveness on removing the AATCC soil.
The purpose of this project is to test the removal of AATCC carpet soil from the given substrates.
Preliminary compatibility tests on substrate coupons encouraging for at least one cleaning chemistry. More in-depth laboratory testing necessary.
