Stoddard solvent is a specific mixture of hydrocarbons, typically over 65% C 10 or higher hydrocarbons, [4] developed in 1924 by Atlanta dry cleaner W. J. Stoddard and Lloyd E. Jackson of the Mellon Institute of Industrial Research as a less flammable petroleum-based dry cleaning solvent than the petroleum solvents then in use.
A better solvent is Stoddard Solvent, or mineral spirits, Coleman fuel, or its camp fuel equivalent [10] All cosmoline cleaning methods create hazardous waste that must be disposed of in the proper manner. Aqueous or solvent cleaning both have accepted methods to dispose of the "sludge" created.
In the United Kingdom, the environmental regulator permits only chemical additives which are classed as non hazardous to groundwater for fracturing fluids.

Since the 19th century, Solvent naphtha has denoted a product (xylene or trimethylbenzenes) derived by fractional distillation from petroleum; [7] these mineral spirits, also known as "Stoddard Solvent", were originally the main active ingredient in Fels Naptha laundry soap. [8] The naphtha in Fels Naptha was later removed as a cancer risk. [9]
The chemical composition of a petroleum distillate can also be modified to afford a solvent with reduced concentration of unsaturated hydrocarbons, i.e. alkenes, by hydrotreating and/or reduced aromatics, e.g. benzene, toluene, xylene, by several dearomatization methods. [1]
Marvel Mystery Oil logo. Marvel Mystery Oil is an automotive product of the American Marvel Oil Company, [1] founded by Burt Pierce in 1923. [2] It is used as a fuel additive and oil additive, purportedly to function as a corrosion inhibitor, penetrating oil, transmission leak stopper and seal relubricator, despite a lack of scientific evidence supporting such claims.
The dressing would be applied sparingly and rubbed into the leather. After two days, the treated leather was polished with a soft cloth. Hard leathers can be soaked in a solution of one part British Museum leather dressing: three parts Stoddard solvent. [4]
