Trial Number 270

Trial Purpose:

Laboratory evaluations of alternative cleaning products

Date Run:


Experiment Procedure:

Basic cleaning performance testing was conducted using ASTM G122 as the bases for cleaning. 

Six products were used at full strength, heated to 120 F on a hot plate. Eighteen preweighed coupons were coated with CRC Industries Multipurpose Super White Grease (64741-96-4, 7620-77-1, 1314-13-2, 57885-77-3, 13463-67-7) and allowed to dry for three days and reweighed. Three coupons were cleaned in each solution for 5 minutes using stir-bar-agitation, rinsed in a tap water bath for 15 seconds at 120 F and dried using air blow off for 30 seconds at 68 F. Coupons were allowed to dry overnight and then reweighed a final time. Efficiencies were calculated.

Note: Bio T Foam Plus was sprayed onto coupons at room temperature and allowed to sit for 5 minutes. The cleaner was then rinsed off.

Trial Results:

None of the cleaners removed over 85% of the grease.  One product was partially successful, removing just over 70%.

Success Rating:

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


No cleaners were successful in removing the grease within five minutes.
