Trial Purpose:
To test the efficiency of SAAFH Device Cleaner in the removal of soil from various substrates
Date Run:
02/10/2021Experiment Procedure:
Aluminum, glass, and plastic coupons were gathered and designated for the two cleaners being tested. Initial weights of the coupons were measured. The carpet soil solution was made using 5 grams of carpet soil mix and 45 grams of mineral oil. 1 gram of this mixture was spread onto each coupon using a swab. Coupons were left to air dry for 1 hour. After the 1 hour, coupons were weighed again to record their contaminated weights. Coupons were then loaded into the gravimetric manual wiping machine 3 at a time. Three of the same substrate were loaded with the first cleaner applied to the cloth wipe in an amount of 2 sprays. This was repeated for the next 2 substrates. This process was then repeated with the second comparison cleaner. Once all coupons had been cleaned, final weights were taken and recorded for each coupon.

Success Rating:
Preliminary compatibility tests on substrate coupons encouraging for at least one cleaning chemistry. More in-depth laboratory testing necessary.Conclusion:
SAAFH Device Cleaner appeared to be more efficient in cleaning contamination off of the substrates than the isopropyl alcohol that it was being compared to in the experiment. SAAFH had a slightly higher overall percentage of cleaning and had higher average percentages on aluminum and glass coupons. Isopropyl alcohol had a slightly higher average percentage on plastic, but not by much. The two products had very similar values with regard to cleaning efficiency, but overall SAAFH cleaned more efficiently than isopropyl alcohol.
