Trial Number 0

Trial Purpose:

To evaluate selected products for the removal of adhesive and fingerprints from glass surface using manual cleaning.

Date Run:


Experiment Procedure:

Eight products were selected from the laboratory's web database,, based on supplied information from the client. Each product was used at full strength and room temperature. In addition, the current cleaning solvent, IPA, was included for comparative purposes.

Twenty-seven preweighed glass coupons were contaminated with a strip of the supplied adhesive tape. In addition, areas not covered with the tape were touched with fingers in order to add fingerprints to the surface. Coupons were weighed again to determine the amount of contamination added. Three coupons were then cleaned with each solution.

Cleaning was performed by soaking a WypAll X60 reinforced paper towel with the cleaning solution. The coupons were then manually wiped for 2 minutes followed by a 10 second wipe with a dry towel. Visual observations were made and recorded during cleaning. Once dry, the coupons were weighed a final time and removal efficiencies were calculated for each product.

Trial Results:

Five of the eight alternatives removed more adhesive than the current solvent IPA. Two products had no effect on the adhesive. Only one product, Kyzen Ionox HC2 removed all of the adhesive and fingerprints from the glass coupons. The table below lists the amount of adhesive/fingerprint added, the amount remaining and the efficiency for each coupon cleaned. Observations also are included.

Success Rating:

Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined.


The five products removing more than the current solvent will be evaluated under conditions more closely matching the current cleaning practice (residual adhesive removal only). Odor comparisons also will be conducted to determine comparisons to IPA.
