Trial Number 0

Trial Purpose:

To identify a replacement cleaner for toluene to remove wax

Date Run:

08/07/2001

Experiment Procedure:

Fifteen cleaners were selected based on past laboratory testing and vendor information. Nine aqueous products and six semi-aqueous were chosen. The aqueous products were diluted to 5% using DI water in 250 ml beakers.
The others were used at full strength in the same size beakers.
Due to limited amount of wax, only one coupon was used in each solution. The wax was heated and applied to preweighed aluminum coupons. After the wax cooled, a second dirty weight was measured. Cleaning lasted for 30 minutes at room temperature, followed by a DI water spray rinse also at room temperature. Coupons were dried using an air gun. Once the coupons were dry, a final clean weight was made and cleaning efficiencies were calculated.

Trial Results:

Of the 15 cleaners only two product removed over 70% of the wax from the aluminum coupons. Bio T Max removed nearly all of the the wax, 99.36%, and D-Greeze 500 Lo removed just over 75% of the wax.

Cleaner Efficiency Classification
Bio T Max 99.36 Semi-Aqueous
Green Stuff 9.88 Alk Aqueous
SC 1000 0.48 Alk Aqueous
SC Aircraft -0.04 Alk Aqueous
Beyond 2003 0.66 Alk Aqueous
DeOx 007 -2.58 Alk Aqueous
Valtron SP 2250 LF 0.24 Alk Aqueous
Daraclean 200 -0.82 Alk Aqueous
Inproclean 3800 -3.06 Alk Aqueous
KPC 820 N 1.75 Alk Aqueous
D Greeze 500 Lo 76.16 Hyrdocarbon
EP 921 24.54 D-Limonene
Engine Degreaser 12.63 Terpene
Methyl Ester 1618 28.46 Methyl Ester
SI # 8 1.8 Semi-Aqueous

Success Rating:

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

Conclusion:

Bio T Max and D-Greeze 500 both were effective in removing the wax.  The aqueous products were only capable of removing less than 10% of the wax if any at all.
