Cleaning Stainless Steel
(These procedures were developed by NAFEM and Packer Engineering.)
1. Use the proper tools. Don’t use; steel pads, wire brush, or scrapers
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.
3.
Keep your equipment clean. Use alkaline, alkaline chlorinated or non-chloride containing
cleaners.
While many traditional cleaners are loaded with chlorides, the industry is providing and ever increasing choice of
non-chloride cleaners. If you are not sure of your cleaner’s chloride content contact your cleaner supplier. If they tell you
that your present cleaner contains chlorides, ask if they have an alternative. They probably will. Also, avoid cleaners
containing quaternary salts as they also can attack stainless steel and cause pitting and rusting.
Use alkaline, alkaline chlorinated or non-chloride cleaners at recommended strength. Clean frequently to avoid
build-up of hard, stubborn stains.
4. Rinse
thoroughly.
Especially if chlorinated cleaners are used, you should rinse thoroughly and wipe dry immediately. The sooner
you wipe off standing water, especially when it contains cleaning agents, the better. After wiping the equipment down,
allow it to air dry for the oxygen helps maintain the stainless steel's passivity film.
5. Never use hydrochloric acid (muriatic acid) on stainless steel.
