Question

How do we clean stainless steel commodes in a jail when they appear to be tarnished from urine and water stains? Also, how can we make stainless steel sinks look better when someone cleaned paint brushes in them and dulled the finish?


Answer

Your janitorial product supplier should have a recommendation for phosphoric acid or liquid pumice-based cleaners. You apply it to the damaged area (commode or sink) and then scour with a green nylon pad. It is crucial to determine the direction of the grain and only scrub with it. Cross-grain scrubbing can leave permanent scratches. Rinse the fixture and re-clean, if required, with your normal cleaning product. Strong hydrochloric acid products should be avoided as they tarnish stainless.
