Trial #10
To evaluate successful cleaners on second oil/abrasive mix.
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.
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.

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).
