Stainless Steel Cleaning & Maintenance
Stainless steel is a bit of a misnomer. Although it resists rust and corrosion, it is by no means impervious to damage and corrosion from weathering, pollutants, and improper cleaning. Stainless steel can also suffer from scratching, gouging, and other damage.
About Cleaning & Types of Stainless Steel
The good news is that proper routine cleaning maintains stainless steel's optimal resistance to staining and corrosion. The UBS #400 specifications are designed to protect and maintain all types of stainless alloys and finishes, including the following two, used most commonly in architectural settings:
| No. 4 Polished |
A general-purpose, polished finish obtained by finishing with 120 - 150 mesh abrasive grinding and graining. |
| No. 2 Bright Annealed |
A highly polished finish achieved by cold rolling followed by final annealing in a controlled atmosphere. |
