Aqueous Cleaning Of Petroleum Compounds From Laboratory Glassware

Petroleum compounds, such as refined hydrocarbon distillates, are generally a difficult-to-clean, oily, molasses-like substance. Traditionally, these compounds are cleaned using hydrocarbon solvents such as diesel fuel; however, this process can be hazardous to personnel and can create environmental disposal problems. In addition, some solvents are illegal due to ozone depleting effects -- and flammable solvents can only be used in a Class I, Division II explosion-proof area. Converting to an aqueous-based method can eliminate all of these concerns and will be less costly. The question is: Will an aqueous system clean as effectively as a solvent-based system? And the answer is yes.
