Rinsing: 1/2 min, manual, in 102 F water (tap)
Drying : 1 min with heat gun @ 500F

Low Foam: This cleaner looked to almost bleach the coupons. It either thoroughly cleaned the coupon of all background and newly added contaminants or it reacted with the aluminum itself.
Success Rating:Preliminary compatibility tests on substrate coupons encouraging for at least one cleaning chemistry. More in-depth laboratory testing necessary.
4 of the 6 cleaners were effective.Perfect Way 147 (82.42 ave % removal). LF-2100 had an average % removal of 106.73. The coupons looked almost bleached with a line where the contaminant and cleaner had been used.
