Rust & Water Spots
Use white vinegar on a soft cloth or sponge. It will not only erase the spots, but will brighten the sink. Rubbing alcohol will also remove rust marks.
Prepare a paste of 3 parts of cream of tarter to 1 part hydrogen peroxide and apply it the stains. Allow to dry and then wipe with a wet cloth or sponge.
Hot water and soap. Clean with a paste of baking soda and water or baking soda and vinegar. Make sure to rinse well and dry the sink.
Chlorides which are found in most soaps, detergents, bleaches and cleansers, are very aggressive to stainless steel. However chlorides are very water soluble and with a thorough rinsing of your sink chloride residue can be removed. If left on the sink surface for too long chlorides can cause pitting of the surface.
Like many metallic surfaces, your stainless steel sink will scratch. These are usage scratches and over time will blend into the overall finish of your sink. The use of a fine pumice powder can reduce the appearance of fine scratches.
Your sink is designed to serve as many things but not as a cutting board or chopping block. This type of use will lead to deep scratches in the sink finish and will dull your knives. Use of proper cutting boards is recommended.
The quality of your water can affect your sink’s appearance. If your water has a high iron content, a brown surface stain can form on the sink giving the appearance of rust. Additionally, in areas with a high concentration of minerals, or with over-softened water, a white film may develop on the surface of the sink. To combat these problems, we suggest that the sink be towel dried after use. Once a week thoroughly clean the sink.
Foods containing high levels of salt should not be allowed to dry on the sink surface. Highly acidic foods such as tomatoes, pickles or lemon should not be allowed to sit on the sinks surface. These can cause pitting of the surface if not cleaned. Always rinse your sink thoroughly after use.
Chemicals such as sulphuric acid, hydrochloric acid are present in many products such as drain cleaners and silver dip cleaners. Photographic chemicals or soldering fluxes will also attack the sink surface. If these products are accidentally spilled onto the stainless steel surface immediately rinse and clean the sink.
