Satin finishes are achieved by "roughening" the surface of the stainless steel. While this surface finish has a unique appearance it can trap dust and other contaminates.

Over time these can stain the stainless steel surface (teatree staining). The build up of contaminates on the stainless steel can be prevented by the application of surface sealers.

Contaminates (and stains) can be 'rejuvenated' by using stainless steel cleaners. 

There are different grades of satin finish, which relate to how deeply the surface is roughened.

Jalex uses a relatively minor satin finish to reduce the extent of contaminate build up, however customers should be aware that even this surface finish will require periodic maintenance with a suitable cleaner. 

Jalex recommends mirror finish for external applications but satin finishes can be used providing the customer accepts there will be a requirement to periodically maintain the surface finish .
