Trial Number 316

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. 

Two products were used at full strength and two others were heated to 130 F on a hot plate. Twelve preweighed coupons were coated with PPG Industries Hi Gord 1035 and allowed to dry for a half an hour 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 for a half an hour and then reweighed a final time. Efficiencies were calculated.

Success Rating:

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


Two products were effective at removing the contaminants at an efficient rate of over 98%. The other two may have started to attack the aluminum coupons as the overall efficiency was in excess of 103%.
