Trial Number 12

Trial Purpose:

To evaluate top cleaning products without rinsing.

Date Run:

02/03/2009

Experiment Procedure:

The top two products were selected from the previous trials based on success on removing tithe supplied soils using heated immersion cleaning. Both were used at full strength based on vendor recommendations. Beakers were heated to 130 F on a hot plate. Steel parts supplied by the client that had grease and oils caked on it. One or two parts  were cleaned in each solution for 5, 10 and 15 minutes using stir bar agitation. Coupons were not rinsed but were dried using compressed air at room temperature for 30 seconds. Parts were visually inspected and pictures were taken.

Trial Results:

Both products were able to remove over 85% of the three soils using immersion cleaning without rinsing. The Bean-e-doo removed over 92%. The table lists the amount of soil added, the amount remaining and the efficiency for each coupon cleaned.

Cleaner 5 minutes 10 minutes 15 minutes
Smart Solve 605 Looks best out of the three times. One part still half caked with soil. Some paint on part and soil in groves  Better then Bean-e-doo. But soil still in grooves
Bean-e-doo Looks best of 3 times. Some soil still on part One part still half caked with soil Not as good as Smart Solve. Soil still in groves

Success Rating:

Results suggest a scale-up feasible match for cleaning chemistry and equipment. Pilot plant study with actual parts recommended.

Conclusion:

Piloting of the two cleaning products should be arranged at the company as the next step.
