Maintenance of metal door knobs is relatively straightforward, another reason for their popularity. Regular cleaning with a gentle soap solution helps remove dirt buildup and prevents tarnishing. For brass knobs, occasional polishing can restore their luster, while stainless steel knobs typically just require a quick wipe down to keep them looking their best.

And visually, the only difference between the two is the texture. Steel is smooth, while iron has a visible grain, whether it is produced by casting, or by pulling. This grain is actually caused by impurities in the iron and is what accounts for its unreliable nature. These impurities cause weak points in the iron that can lead to breakage when it’s put under stress. Steel’s smooth appearance results from the fact that these impurities have been burned out, or, in the case of carbon, evenly distributed throughout the material. When you think of the medieval blacksmith hammering away, what he is doing is distributing the carbon evenly to turn iron into steel.
