Trial Purpose:
To evaluate successful cleaners on second oil/abrasive mix.
Date Run:
02/06/2003Experiment Procedure:
Six products were selected from the lab's database based on previous tests results. The semi aqueous terpenes were used at full strength in a 600 ml beaker. The other four 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 Aluminum Oxide 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:
All six products removed over 95% of the oil/abrasive mix. Three cleaners, Safety First, LPS Precision Clean & US Polychemical removed over 99% leaving the coupons with no visible trace of the oil/abrasive mix. The table below lists the amount of oil/abrasive applied and removed.

Success Rating:
Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined.Conclusion:
All six products were successful in removing the oil/abrasive mix within 5 minutes using immersion cleaning.
The next trial will be to remove mounted parts from the metal plates and remove the wax using immersion cleaning with manual wiping (if necessary).
