I'll start with what is probably the most important piece of advice I can give you: Don't be afraid of the knob. They come in all shapes, sizes and colors but they all work the same way. Remember, the knob will not hurt you, contrary to what your mother may have told you. She probably just said that because during her frenzied knob polishing freshman year of college, she polished the wrong knob during homecoming. Which just goes to show you, ladies. Select your knob carefully.
Once you have chosen your knob you will need to prepare yourself for the task ahead by dressing comfortably. Knob polishing can be strenuous so you might work up a sweat. There are a few products you will need to have on hand as well as a good supply of rags and towels since, if done correctly, knob polishing can get messy.
When you begin polishing it is important to look your knob in the eye. Let it know that you mean business. Find a position that is comfortable for you in case your knob proves to be a stubborn polish. No need to resort to the knee pads our mothers used to use. The modern woman knows that her own comfort and satisfaction are the key to a successful knob polishing.
Use the products you have on hand to bring your knob back to a full shine. Be sure to give plenty of attention to the underside of your knob which can be come crusty and discolored if neglected.
Once your knob has reached it pinnacle of shine, be sure to step back and bask in the afterglow of your shiny knob. Newer knobs might need to be polished much more frequently than older knobs but with some practice you will be able to give it a quick buff on your way out the door. As one friend pointed out, polishing an older knob might take some time but the satisfaction you get when it's done is worth it.
