Compositions and methods are provided for cleaning and de-oiling metal parts and then degrading the removed oils or other organic compounds in an environmentally-friendly manner. The compositions generally contain surfactants to remove the oils and enzymes to degrade the oils. Generally, both aliphatic and aromatic compounds normally present in standard oils, lubricants, cutting oils, and greases are removed from the metal parts (i.e., "solubilized") by surfactants (although the enzymes may also assist in this process) and then ultimately broken down into relatively short-chain fatty acids by enzymes, both processes being carried out in an aqueous medium. The surfactants include (a) one or more alkylphenol ethoxylates; (b) one or more alkaline metal salts of an alkane sulfonic acid; and (c) one or more alkanolamines in aqueous solution. Suitable enzymes include monomethanoxigenase, alcoholdehydrogenase, and aldehydehydrogenase. Preferably, the aqueous enzyme solution contains all three types of the just-listed enzymes in order to degrade a wider variety of organic compounds derived form petroleum and petroleum products.
