If the strap of your watch is made of leather, you should learn how to protect your leather watch with a good cleaner. For thousands of years, people have chosen leather for their clothing, shoes, and accessories because of its timeless design that works well for both formal and everyday wear. Many of our watches include leather bands that come in a variety of colors, from classic black and brown to more modern shades of color. Cleaning the leather band is a necessary component of caring for your leather watch. However, in order to maintain leather's appearance and avoid any damage, it must be cleaned properly. Leather is a special kind of material that needs to be cleaned with particular care. Leather can be sensitive to liquids and absorbs the sweat and filth that occur with everyday use. The substance is also susceptible to other factors, such as heat or direct sunshine, which can result in breaking. How to clean a leather watch band is shown below:
- Take away the strap
Before cleaning the watch, take off the strap. This shields the dial and casing of the watch.
- Use a dry cloth to wipe the leather.
Wipe the strap down with a dry cloth before involving any liquids. This gently clears away any gritty dirt or debris that has accumulated on the strap and may otherwise cause the leather's surface to be scratched during a more thorough cleaning. Pick a soft cloth; your finest options are microfiber or jewelry polishing cloth. 
- Use soap to clean the leather.
The strap needs to be scrubbed with soap more thoroughly. The leather might become dried out by stripping formulae found in harsher soaps, so a soft soap is preferable. Apply a tiny amount of the soap on a moistened microfiber or jewelry cloth. To prevent the leather from being harmed by water, the cloth should be damp but not drenched. Use the damp cloth to gently rub both the inside and the outside of the leather band, going in small circular motions.
- Eliminate soap leftovers.
After washing the strap, thoroughly rinse the towel in running water to remove all of the soap. Remove any extra water from the towel by squeezing it. Once all soap residue has been removed from the band, lightly wipe the leather strap with a clean, moist towel.
- Allow band to dry
Allow the strap to air dry after the soap has been removed. Avoid using a hair dryer or placing the strap in direct sunlight to dry it.
- Apply conditioner to the leather
Apply the number of drops of leather conditioner recommended on the packaging to a clean cloth once your strap has dried. Use the cloth to gently rub the leather strap, then let it air dry. Make sure the leather conditioner you use is for jewelry, watches, apparel, or accessories because it probably won't be gentle enough for skin contact if it's for furniture or other industrial things. 
If you're looking for a regimen to maintain a leather strap that you use frequently, cleaning the strap once every other week is a fantastic suggestion. To clean your strap, follow the directions above, omitting the conditioner step. Check the conditioner packaging for specifics. The leather conditioner is intended for sporadic use. You might want to think about washing down your leather watch strap more frequently if you live in a hot or humid region because of perspiration. Similar to this, leather jewelry may need to be cleaned more frequently in the heat. Find Some F.A.Q is provided here for you to help you to clean your leather watch straps. When should I clean the leather strap on my watch, and how often should I do it? This will almost certainly be determined by the location, environment, and situations that your watch is exposed to. For instance, if you live in an area that is both dusty and hot, you should wipe down your strap as frequently as you can so that it remains clear of bigger debris and remains dry from the sweat that you produce while wearing it. In climates with more moderate temperatures, the process of cleaning the watch strap as described above should be carried out approximately once every two to four weeks (with the exception of Step 7; see below for more information about this step). However, you should play it by ear and determine how often it needs cleaning based on how dirty it gets, how it smells, and how it appears. When was the last time you conditioned the leather on your watch band? 
This is difficult to answer in a broad sense because it will depend on the weather conditions in the area in which you reside as well as the sort of air conditioner that you use. You should check the instructions on the packaging of your conditioner to determine how often you should apply it, although the frequency of your applications should not be excessive. You may take care of your leather watch strap in a variety of other ways in addition to limiting the amount of time it is exposed to moisture and perspiration, including the following: Put some slack in the strap, then wear it. When you move your wrist, a strap that is worn too tightly will experience stress. This can cause the strap to wear out far more quickly than it would have otherwise. A strap that is worn too loosely does not get harmed in this way, and it also has the added benefit of not restricting the blood flow in the wrist, which is a significant benefit (unlike a tightly worn strap). Maintain a safe distance between the strap and any cosmetics. When applying sunscreen, perfume, skin lotions, or any other type of cosmetics near the leather watch strap, use extreme caution. When these cosmetics come into touch with the band, the leather may become discolored and even stained as a result. 
Reduce your time spent in the sun and the heat. Leather that has been exposed to heat will dry out and crack, but leather that has been exposed to sunshine will darken over time. If the watch band has come into contact with moisture and needs to be dried, you should make sure to do so in a shady location where it may be allowed to air dry.
