Trial Purpose:
To find cleaners for oil and abrasive removal
Date Run:
02/04/2003Experiment Procedure:
Five products were selected from the lab's database based on previous testing results. A sixth cleaner was selected based on supplied client data. The semi aqueous terpene was used at full strength in a 600 ml beaker. The other five products were diluted to 5% using DI water in 600 ml beakers. All six products were heated to 120 F on a hot plate. Eighteen preweighed coupons were coated with Speed Fam Industrial Applications Vehicle 210 with Boron Carbide abrasive using a hand held swab. The oil/abrasive mix was forced dry using a Master Appliance Heat Gun at 500 F for 3 minutes. Coupons were allowed to cool to room temperature and weighed a second time. Three coupons were immersed in each solution and cleaned for 5 minutes using stir-bar agitation, rinsed in tap water for 15 seconds at 120 F and dried with the heat gun for 30 seconds at 500 F. Once coupons were cooled to room temperature, final weights were recorded and cleaning efficiencies were calculated.
Trial Results:
Five of the six products removed over 85% of the oil/abrasive mix within five minutes of cleaning. Two products, Safety First and Polyspray Jet 790 XS removed over 95%. The table below lists the amount of oil/abrasive applied and removed for each coupon.

Success Rating:
Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined.Conclusion:
The five successful products will be used in the next trial with the aluminum oxide based abrasive. Cleaning times may be increased to improve efficiency.
