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

Two products were used at full strength at room temperature and four were heated to 130 F on a hot plate. Twenty-four preweighed coupons were coated with Jackson Lea Antique Buffing Compound (cm-12) 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.

Beyond 2003 was the only effective cleaner at an efficiency rate of over 85%.
