If you have a removable band on your watch, it is a good idea to separate it from the face and the mechanical part of the watch for the cleaning. This is because you should avoid getting those parts of your watch wet. If you aren't able to remove it, don't worry. You just need to make sure that you don't damage to working parts when you apply the cleaner.
Step 2: Choose a cleanser.
You should use a mild soap or rubbing alcohol for most types of watches. If you have a gold watch, or it is made of silver or a platinum material, you might consider using a small amount of jewelry cleaner. Using water alone is not going to be very effective. If you do use some water, make sure that it is mixed with a mild soap (such as dish soap) and don't get the inside wet.
Step 3: Use a soft cloth or a soft toothbrush.
Don't use a scrubber sponge, a hard bristle toothbrush or paper towel. Abrasive materials can add scratches to your watch that you don't want. Make sure that you use a soft material to wipe away stains, oils and germs. Rub gently in a circular motion to clean your watch.
Step 4: Make sure it's dry.
It is important to make sure that you remove all of the moisture from the band of the watch, and any other part of the watch that may have gotten wet. Even though you do not use very much liquid during the cleaning process, you will want to make sure that there isn't any moisture left. If you leave it wet, mildew might develop, and you don't want that on your watch! Also, depending on the material it is made out of, wetness can cause rust. Make sure that you take a smooth, dry cloth and dry your watch well.
That is all. Now you can put your watch band back on and wear your watch. You might want to leave it alone for a while since you put the work into cleaning it, however. Anyway, that is all there is to it, and you can clean your watch every couple of months to keep it shiny and nice.
