Mr. Muscle

From Wikipedia, the free encyclopedia

Mr. Muscle is a brand of hard surface cleaners primarily used for cleaning ovens.

It has been manufactured by S. C. Johnson & Son, since their purchase of Drackett from Bristol-Myers in 1992. The original product was developed at Drackett in the early 1970s.

Oven cleaners at the time were pretty much all the same as Reckitt & Colman'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, and working in a fairly close space with hot oven cleaner fumes was unpleasant, to say the least.

Appliance manufacturers offered continuous-clean ovens, which had a special coating. Consumers found these were continuously not-very-clean - and the use of chemical oven cleaners ruined the continuous-clean coating. They offered self-cleaning ovens, which basically allowed the oven to heat up without let, burning food spills away. They weren't thoroughly satisfactory, either, at worst leaving carbon still stuck to the oven, and at at best leaving a residue on the oven floor.

Industry legend has it that Drackett researchers, in trying to find a cold oven cleaner, found that ammonia would plasticize food spills, making them easier to remove. However, this took hours - and ammonia would evaporate in that time. Looking for a less volatile chemical with the general characteristics of ammonia, they found that monoethanolamine had similar properties.

MEA is a weak base, so it required the addition of caustic soda as well as surfactants and bentonite as an abrasive. Like most household cleaning aerosols, the propellant is a blend of propane and isobutane. Because the product required significant time to work properly, it was marketed as an overnight oven cleaner.

The product quickly grew to have be number two in the product category. As unappealing as strong fumes are, dragging out the cleaning process and awakening to the joyful task of wiping strong chemicals and grease out of an oven isn't exactly attractive either. There was no official website for Mr. Muscle, suggesting that S. C. Johnson wasn't excited at growth potential of the product. However, there is now one available for the public to view.

[edit] Trivia

Chemist Gary Bush, who led Draclett's product development of Mr. Muscle at the time, used the handle of Mr. Muscle during the CB radio craze of the 1970s. In September 2006 They changed the Mr. Muscle from the famous man to another new actor due to a pay dispute.
