Stainless Steel Cleaning and Maintenance
Under normal usage, stainless steel products require regular cleaning with a soft clean rag moistened with a mild detergent followed by a water moistened clean rag and then a dry rag, much the same as stainless steel sinks, pot & pans and eating utensils, and can be wiped with lemon oil applied by soft polishing cloth to maintain sheen.
The 9343 #4 satin finished stainless steel should be protected against Muriatic acid and caustic or abrasive materials, and harsh cleaning detergents [with pH outside the range 6 ± .5]. In the event such agents cause discoloration, polish with a stainless steel cleaner such as 3M Stainless Steel Cleaner & Polish and a 3M Scotch Brite pad. Either a blue (less aggressive) or green (more aggressive) pad is recommended.
