Where did it all begin?

Nonstick coatings hit the selling floors in the early 1960s.

The first nonsticks were made primarily of polytetrafluoroethylene (PTFE). PTFE has the lowest coefficient of friction (CoF) of any known solid. In other words, the majority of materials (in this case foodstuffs) do not stick to it.

PTFE's low CoF "releases" the materials, making it easy to separate them from the coating. Therefore, on nonstick pans, most substances are easily removed from the surface.

Unfortunately, PTFE is also very soft and, if unprotected, wears quickly. While early nonsticks had good release, they were soft and wore out after little use. The result: nonstick-coated cookware earned the reputation of being "disposable".

Alkaline Wash

A properly maintained alkaline wash system will effectively clean most organic and inorganic surface contaminants. By varying the strength of the alkaline solution, these washers can apply an effective alkaline etch to certain metal substrates, like aluminum, and in some cases eliminate the need for further substrate pretreatments like grit-blasting. An alkaline wash is an effective pretreatment prior to grit- blasting as it will reduce contamination of the blast media, and thus extend the media's usable life.
