Trial Number 4

Trial Purpose:

To evaluate final product on four previously submitted soils as a follow up to other products tested.

Date Run:

01/08/2008

Experiment Procedure:

The supplied product was diluted to the five percent and heated to 135 F on a hot plate. Twelve preweighed Aluminum 6061 T6 coupons were coated with the four contaminants, three per contaminant using a handheld swab. Coupons were weighed a second time to determine the amount of cutting fluid added.

Three coupons were immersed in each solution and cleaned for five minutes using minimal stir-bar agitation. Coupons were rinsed in tap water heated to 135 F. All coupons were dried for 10 minutes in an oven at 140 F. After drying, coupons were weighed a third time and product cleaning efficiencies were calculated.

Contaminants Include:
Cinster cutting fluid
Clean Tool II lubricant
Blaser Vascomil 22 cutting fluid
Haycut SW 220 cutting fluid

Trial Results:

The supplied cleaning product was successful on all four contaminants using immersion cleaning, removing over 90% of the cutting fluids/oils within five minutes. The table below lists the amount of soil added, the amount remaining and the efficiency of the product for each coupon cleaned.
