sandpaper or by chemical means. Then
paint with primer or
solvent-based paint.

Care of Stainless Steel
Maintain the natural beauty of stainless steel
and prolong its service life by
following these steps:
1.
Ordinary deposits of dirt and grease can be
removed with detergent and water. The
metal should be thoroughly rinsed and
dried after washing. Periodic cleaning will
help to maintain the bright surface
appearance and prevent corrosion.
2. Contact with dissimilar metals
should be avoided whenever possible.
This will help prevent galvanic
corrosion when salty or acidic
solutions are present.
3.
Salty or acidic solutions should
not be allowed to evaporate and
dry on stainless steel. They may cause
corrosion. Ensure that the stainless steel is
wiped clean of acidic solution residues.
4.
Deposits that adhere to the stainless steel
should be removed, especially from
crevices and corners. When using abrasive
cleaners, always rub in the direction of the
polish lines or “grain” of the stainless steel
to avoid scratch marks. Never use ordinary
steel wool or steel brushes on the stainless
steel. Use stainless steel wool or soft non-
metal bristle brushes.
5.
If the stainless steel appears to be rusting,
the source of the rust may actually be an
iron or steel part not made of stainless
steel, such as a nail or screw. One remedy
is to paint all carbon steel parts with a
heavy protective coating. Stainless steel
fasteners should be used whenever
possible.
