Trial Number 0

Trial Purpose:

To eliminate the use of N-Propyl Bromide in cleaning opereations

Date Run:

02/29/2016

Experiment Procedure:

To evaluate possible immersion cleaning process for Brookfield compared to other cleaning solutions.

Four cleaners were tested at room temperature on aluminum, brass, and stainless-steel coupons to evaluate how the soil, Castrol Performance Bio NC Lite, was cleaned. Preweighed coupons were coated with the supplied Castrol soil using a hand held swab and weighed a second time to determine the amount of soil added. Each cleaner was put in a beaker and three coupons were immersed into the solution for 5 minutes. The coupons were then stood upright to air dry for 15 minutes at room temperature and then placed on a tray. There was no rinse. Once dry, final weights were recorded and efficiency calculated 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 four cleaners efficiently removed the Castrol soil on all three substrates at room temperature. The least efficient cleaner used was Fluosolv NC, with the lowest cleaning average on the brass substrate. The Fluosolv NC was still an efficient cleaner with a 94.13% efficiency, but less efficient than the other cleaners used. The most efficient cleaner would be Solstice 2A from Honeywell which had an efficiency of 98.90%.
