How to Get a 4 Finish on Stainless Steel

Giving your stainless steel surfaces a mirror-like finish is easier than you think. With the right tools and materials, you can achieve professional results in no time. Whether restoring an old sink or polishing up the handles of your favourite kitchen utensils, read on to learn how to get a 4 finish on stainless steel.

Tools You’ll Need

Before getting started, it’s essential to make sure you have all the necessary supplies. Depending on the size and condition of your stainless steel surface, you may need some combination of the following items: pliers, wire cutters, sandpaper (150 grit, 400 grit, and 600 grit), white vinegar, baking soda, cotton cloths or paper towels, an electric sander or polisher (optional), and a buffing wheel.

Cleaning and Sanding

Begin by cleaning the surface thoroughly using white vinegar and baking soda. This will help remove any dirt or oil that could interfere with the process. Next, use 150-grit sandpaper to remove any rust spots from the surface if necessary. Once all rust has been removed, switch out your sandpaper for 400-grit paper and lightly sand the entire surface until it is smooth and even. If needed, use 600-grit paper for finer details like corners and edges before moving on to buffing.


You can use a cotton cloth to buff small surfaces like metal handles or knobs in your kitchen or bathroom fixtures. For larger surfaces like a sink basin, an electric sander/polisher with a buffing wheel attachment is recommended for best results. Start by applying metal polish with long strokes in one direction only – this helps prevent unsightly swirl marks from appearing on the finished product! Then turn on the buffer/polisher (if using) and apply gentle pressure as you move over the entire surface until it has taken on a high shine – almost like glass!


Achieving a 4 finish on stainless steel surfaces is easier than it may sound; it just takes patience and attention to detail! With these easy steps, you can have beautiful results that look like they’ve been professionally done. Always wear protective goggles when working with power tools such as electric buffers/sanders so that no accidents occur – safety first! And be sure to clean up properly when finished so that no corrosive materials remain behind that could harm other objects in your workspace. Achieving perfect stainless steel finishes doesn’t have to be daunting; follow these steps for beautiful results every time!
