Trial Number 0

Trial Purpose:

To evaluate selected products on first supplied soil using immersion cleaning

Date Run:

06/18/2008

Experiment Procedure:

Ten products were selected from the lab's on-line database, www.cleanersolutions.org, based on supplied information from client. Each product was diluted to 5% using DI water in 600 ml glass beakers. Solutions were heated to 130 F on a hot plate.
Thirty preweighed steel coupons were coated with the Castrol Industrial Inc Safety Draw 722X (61788-76-9, 64742-54-7) using a swab. Coupons were weighed a second time to determine the amount of soil added. Three coupons were immersed into each product and cleaned for 5 minutes using minimal stir-bar agitation. Following cleaning, coupons were rinsed for 15 seconds in tap water at 120 F and dried using air blow off for 30 seconds at room temperature. Final weights were recorded and efficiencies were calculated.

Trial Results:

No product was very successful using immersion cleaning to remove the Safety Draw fluid. Three of the products had marginal success, removing over a third of the soil in time frame. The table lists the amount of soil added to the coupons, the amount remaining and the efficiency for each coupon cleaned.

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 three products that were partially successful will be evaluated using ultrasonic cleaning. Additional products will be selected from the lab's inventory as well.
