Mr Muscle is a British brand of hard-surface cleaners. It has been manufactured by S. C. Johnson & Son, since their purchase of Drackett from Bristol Myers Squibb in October 1992. The original product—an aerosol oven cleaner—was developed at Drackett in 1986. The Mr Muscle product lineup has since expanded.
Oven cleaner
History
Oven cleaners at the time of introduction (1986) were generally similar to Reckitt's Easy-Off, the leading brand. A strong base, such as caustic soda, attacked grease by saponification. Surfactants attacked both grease and food spills. An abrasive may be present to help scour the oven. The product worked better if the oven was hot, although working in a fairly close space with hot oven cleaner fumes was unpleasant.
Appliance manufacturers offered continuous clean ovens, which had a special coating. Consumers, however, discovered these ovens were rarely cleaned by the process. Additionally, supplemental use of chemical cleaners destroyed the special coating that enabled continuous clean to function.
