KING WATCH CO. suggests the following solutions for cleaning metal and crystal surfaces:
3:1 Solution of Ammonia-based indoor cleaner to water
4:1 Solution of rubbing alcohol to water
Do not use soap products, as soap will leave behind when dry. These suggested solutions will evaporate cleanly from metal and glass surfaces.
TO CLEAN THE CASE AND CRYSTAL
Moisten a soft cloth with one of the above solutions. Gently wipe the case and crystal clean. Be careful not to put too much stress on the crystal as you clean. Avoid immersing or soaking the case or crystal portion of the watch, regardless of water-resistance rating.
TO CLEAN THE BAND OR STRAP
Dip a cotton swab into one of the above solutions and gently rug it on the unclean area of the band. For more intricate mesh bands, you may want to use a soft-bristle toothbrush or nailbrush. Be sure to cover the case of the watch during this process so as not to soak it.
Simply wipe it clean with a damp cloth, using water only. you may want to use leather conditioner or a small amount of hand lotion to keep the leather supple over time. Top-grain leather may develop a milky "haze" if left alone for extended periods. This can simply be wiped away or removed with leather conditioner. A product called "unbuckle eraser" can be used to remove light stains and debris from the inside of the strap.
