Cleaning tips for Stainless Steel

Stainless steel is a material that is used extensively in bathrooms as it is naturally resilient against corrosion and offers a good level of stain resistance too! Why is this so? Stainless steel contains chromium which reacts to oxygen in the air and forms a “passive” protective film over the steel. This prevents problems like rust and reduces stains and discolouration. However, if the steel surface is coated with grease or dirt, this reaction can’t happen!

To have an optimum corrosion-resistant stainless steel, surfaces must be cleaned and have an adequate supply of oxygen to maintain their “passive” surface layer.

Cleaning of Stainless Steel

Alkali cleaners such as baking soda or ammonia are effective to clean stainless steel. Always attempt the mildest cleaning method first. Stainless steels best friends are quite simply soap, mild detergents or ammonia solution in warm water applied with a soft cloth or nylon sponge for polished finishes followed by a clean water rinse. 

What to avoid

Do not use ordinary steel wool. Iron particles can become embedded in stainless steel and cast iron contamination.

Do not use chlorides or acids as they are reactive to stainless steel. Strong acid solutions like hydrochloric acid or spirits of salts are sometimes used to clean masonry and tiling of new bathrooms ad toilets, but they should NEVER be permitted to come into contact with metals, including Stainless Steel.

Never use brick cleaning liquids that contain hydrochloric acid. Many cleaning solutions and solvents contain chlorinated hydrocarbons. If a cleaner containing chlorides, bleaches and hypochlorite’s are used, it must be promptly and thoroughly cleaned off.
