Stainless steel is the generic name for a number of different steels used primarily for their resistance to corrosion. The one key element they all share is a certain minimum percentage of chromium of 10.5%. Although other elements, particularly nickel and molybdenum, are added to improve corrosion resistance, chromium is always the deciding factor. However, despite its various additions stainless steel still behaves as steel, and even the highly alloyed stainless steel grades such as 316 still contain a minimum of 62% iron.
PNZ manufactures using 304 grade stainless steel with an electro-polished (EP) finish brushed finish. Electro-polishing is widely used in the electronics, food and medical industries and on components for cruise ships and yachts, where a corrosion resistant, smooth and easy to maintain surface is of vital importance. Electro-polishing is an electrochemical process whereby the combination of an electrical current and a strong acid erodes the surface of the stainless steel substrate atom by atom. This process removes much of the iron from the surface of the steel, but leaves the chrome intact, resulting in more shiny, but much improved corrosion resistant surface.
CARE AND MAINTENANCE
- Use a dry, clean cloth to dust furniture weekly and maintain luster.
- For spot cleaning, spray off any debris with a hose and brush off any dirt or debris with a soft-bristle brush. Dry with a soft cloth.
- Furniture should be thoroughly cleaned periodically, using a soft towel with a premium auto or marine soap. Do not use cleaning products designed for uncoated stainless steel hardware, such as our Innopolish, Innoshine and Innocare stainless steel cleaners. Rinse with water and dry with a soft cloth.
- Metal furniture can also be waxed twice a year to protect the finish. We recommend using Meguiar’s® Quick Wax. Before waxing, furniture needs to be thoroughly cleaned. Use a soft cloth to apply a thin layer of wax and buff with a microfiber towel.
- Avoid hitting metal furniture pieces against one another and avoid dragging along the ground. On tabletops, we recommend placemats to avoid scratches that can chip the finish and promote oxidization.
- If furniture is in a saltwater environment, rinse off and wash with soap weekly to remove all salt, as salt deposits can damage the finish. We recommend using Dawn® or Method® soap.
- If furniture is in a freezing environment, thoroughly clean and dry, then store in a dry place such as a garage or shed. If storage is not available, furniture should be covered with our custom-fit outdoor furniture covers.
- Avoid letting water stand on the surface of your furniture and cushions.
- When furniture is not in use for an extended period of time, protect it with our custom-fit outdoor covers. Before covering, furniture needs to be thoroughly cleaned and dried. Cushions should be removed and stored in a dry place.
