Special Note for Toilet Partition Hardware
Although stainless steel is very resistant to rust, there are certain conditions where this can happen
depending on various factors listed below:
• Cleansers containing Chloride or Muriatic Acid (hydrochloric acid).
• Concentrated soap residue where chemical additives to soap may cause discoloration and
potentially dry out and result in a rusting appearance.
• Environments where water has high iron content or where contact with iron occurs (such as
steel wool, machining chips or iron residue or dust from installation or cleaning of other steel
products) can leave a rusty residue.
• Presence of salt containing chlorides.
Remove rust discoloration or corrosion as soon as possible to prevent permanent discoloration
and pitting of the surface. Regular cleaning can restore the original condition in most cases with
proper maintenance and cleaning. DAILY cleaning should prevent discoloration (rusting and
rusting appearance) and corrosion in high moisture environments such as showers and shower
compartments.
Materials and Tools Required:
• Mid abrasive cleaner such as Bar Keepers Friend (available at Home Improvement or Discount
Stores).
• Soft Sponge and/or 3M Scotch Brite pad #7447 or equivalent.
Follow the Steps Below During Daily Cleaning:
1. Apply a generous amount on the affected areas and rub with a damp sponge in the direction of
the grain. NOTE: Avoid using caustic cleaners that contain chlorides as the abrasive nature of
these products will further damage the steel’s chromium fi lm.
2. Rinse with clear water and gently towel dry.
3. Repeat cleaning process daily or more often depending on severity of rusting.
