There are various grades of stainless steel, each offering a variety of corrosion resistance and finishes. Some grades are designed for general use, while others are utilised in industrial and even marine settings. Despite its name, all stainless steel can be subject to grime build up and marking, especially when it is placed in a dirty environment. However, it is quite possible to bring all grades of stainless steel — no matter where it happens to be — up to a standard that is as good as new. A variety of methods should be used to clean stainless steel, depending upon the particular requirement.
Light Soiling and Fingerprint Marking
Brushed stainless steel is often used in buildings and street furniture to provide a robust yet shiny surface. It does, however, get grimy when touched or can face streaks if rainwater runs off it. Sponging on soapy water is usually all that is needed to bring stainless steel back to an attractive finish and you can prolong the look of the clean metal by allowing it to dry then applying a spray polish to the surface with an unsoiled rag.
Burnt on Substances
Often used in food manufacturing plants, stainless steel can be subject to food deposits which get burnt on and become hard to remove. Anywhere where paint finishes are applied to stainless steel products which are kiln dried can also face this issue of stubborn staining. Burnt on substances in manufacturing settings need professional industrial cleaning services to remove them fully due to the need to keep equipment in good working order at very high temperatures. For burnt on deposits in a domestic setting, such as a barbecue grill for instance, use an abrasive souring powder, but bear in mind that this can leave unsightly scratch marks on polished steel products.
Hard Water Scaling
In places where stainless steel has a build up of limescale, such as quay sides, pleasure boats or even the taps in your bathroom, it is best to take regular action before the problem gets too bad. Cream cleaners are the best ones to use in the home. Apply these with a sponge and a soft scouring pad so that your steel does not become permanently marked. Look for specialised liquid scrubs for cleaning outdoor steel products, such as bollards. Such cleaners are tough but ensure that the finish of the stainless steel remains shiny.
In a factory setting where stainless steel is quite common, you might also consider hiring industrial cleaning services to have help keeping everything in great shape.
