As a metal, stainless steel can easily lose its luster with time and usage. To ensure that the product is fit for longer use, many companies utilize metal polishing methods to maintain the strength and beauty of steel products.

There are many advantages to metal polishing.

Metal finish polishing provides a much smoother surface finish

Metal polishing also improves the cleanliness and overall hygiene of the stainless steel product

The overall aesthetic appeal can be improved with stainless steel polishing

Polishing can help to strengthen the steel against corrosive substances

When stainless steel is used on moving parts, metal polishing can help to reduce the total amount of friction being applied

Metal Polish Finishes

Professional metal manufacturers or suppliers usually provide metal polishing services along with their products. Depending on the type of metal used, the manufacturers offer different types of metal finish polishing. Some of the well-known finishes are mentioned below.

2B Mill Finish: This is a standard finish known for its smoothness, reflective qualities, and brightness. 2B Mill finish can also provide a slight luster to the metal. It is also used as a pre-finish before a second coat of polish is applied.

#4 Polish Finish: This particular finish has a grit grain count of 180. It is generally used for sanitary areas that do not require high luster or a mirror like finish.

#8 Mirror Finish: This is also known as a dairy finish as it is used on dairy tanks with a high reflective finish. This is perhaps the best method for stainless steel metal polishing.

Metal Polishing Techniques

The techniques for metal finish polishing can range from simple to complex. Depending on your requirement, you can either do it yourself or you can hire a metal polishing company to do it for you. Nonetheless, there are certain points that you need to keep in mind:

1.Make sure you clean the stainless steel product before you start. Use a soft, clean cloth and wipe the entire surface of the product with a warm water solution mixed with dish cleaning detergent.

2.Water can be a huge problem when performing steel polishing. Once you have cleaned and washed the product, use a clean cloth to dry out all the water. Air drying is also an option although that can leave stains on the metal.

Once these steps have been taken care of, you can use any of the following methods to polish your metal items.

Using Olive Oil: The properties of olive oil allow for quick and easy metal finish polishing. Use only a small amount of the oil as it spreads quite easily on the steel. Soak the oil on a cloth and thoroughly wipe the item. Finish it by using a paper napkin to buff the product.

Using Flour: This method involves using flour as a buffing agent. Spread a small amount of flour onto the product and buff it with a clean cloth. Once the shine has been restored, use the same cloth to remove any excess flour.

Professional Metal Polishing: This is effective for large surfaces. The method requires the assistance of a professional with a special power buffer and a buffing pad. A stainless steel polish is poured onto the buffing pad. The professional then uses the power buffer to spread the polish onto the surface. The process is completed by using a clean cloth to wipe the item down and remove any excess polish.

With effective stainless steel polishing methods, your products can regain their strength and aesthetic appeal.
