To evaluate Methyl 408 and Ethyl 408 on their removal effectiveness of different soils on different substrates.
Date Run:
06/11/2015
Experiment Procedure:
GS34 Soil 1 was the maintenance soil that was made up of 10 grams of carbon black, 10 grams iron oxide, 100 ml WD-40, 100 ml hydraulic oil, and 100 ml gear oil. Ethyl 408 performed better at removing this soil from stainless steel. The GS34 Soil 2 was the production soil which was made up of 200 ml Quench Oil and 200 ml cutting oil.
Trial Results:
Both Methyl 408 and Ethyl 408 were excellent at removing this type of soil off of stainless steel. Both chemicals, in a span of 30 minutes, were able to take off at least half of the Apiezon Grease. If left immersed in these chemicals longer, the grease would most likely have been completely removed.

Success Rating:
Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined.
Conclusion:
Overall, Ethyl 408 removes an average of 90.99% of oils, and Methyl 408 removes an average of 88.49%. Methyl 408, however, is better at removing grease.
