Seven products were selected from the laboratory's web database, www.cleanersolutions.org, based on supplied information from the client. Each product was used at full strength and room temperature. Twenty-one preweighed glass coupons were contaminated with a strip of the supplied adhesive tape. 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.
Three of the seven products removed more than 90% of the adhesive within 2 minutes of the manual wiping and three removed more than 60%. The Green Works Glass cleaner need less than a minute to remove nearly all the adhesive. The table lists the amount of adhesive added, the amount remaining after cleaning and the efficiency for each coupon cleaned.
