Seven cleaners were selected from the laboratory's database of past testing based on supplied data from client. Six aqueous based cleaners were diluted to 10% using DI water in 600 ml beakers. One semi-aqueous product was used at 50% diluted with DI water. An eight product was added as the client's current cleaner. All of the products were heated to 120 F on a hot plate.
Twenty-four preweighed aluminum coupons were coated with client supplied cutting fluid, Speedfam Vehicle 210 mixed with an abrasive. The oil and abrasive were first mixed in a bottle. The mixture was added to coupons using a swab and then heated for 10 minutes using a Master Appliance heat gun. The coupons were allowed to cool to room temperature before weighing a second time.
Three coupons were cleaned in each solution for 10 minutes using stir-bar agitation. Coupons were not rinsed but were dried using air blow off at room temperature. Once dry, coupons were weighed a final time and efficiencies for each cleaner were calculated.

Four of the eight products removed over 74% of the oil/abrasive mix within five minutes using no rinsing.  The Bio T 300 B removed over 97%.  Most of the coupons had an oil film remaining except the Bio T 300 B. The client's current cleaner, Bruilin 815 GD removed 68% of the oil. The following table lists the amount of soil added, the amount remaining after cleaning and the efficiency for each coupon cleaned.

The four effective products and the current cleaner will be tested under the same conditions except a water rinse will be added.
