with extremely hard water, it may be necessary to do this weekly. Monthly cleaning may be sufficient in areas with
average water conditions.
Care of Stainless Steel
(These procedures were developed by NAFEM and Packer Engineering.)
1. Use the proper tools.
When cleaning your stainless steel products, take care to use non-abrasive tools. Soft cloths and plastic
scouring pads will not harm the steels passive layer. Stainless steel pads can also be used but the
scrubbing motion must be in the direction of the manufacturers polishing marks. Step 2 tells you how to find
the polishing marks.
2. Clean with the polish lines.
Some stainless steels come with visible polishing lines or "grain." When visible lines are present, you
should always scrub in a motion that is parallel to them.
When the grain cannot be seen, play it safe and use a soft cloth or plastic scouring pad.
