Different stainless steel watches require different bracelet detachment methods.  Some will need only a simple click of a button to detach their bracelet from their watch head.  Others will need a specialized screwdriver to release the bracelet from the watch head.  Consult manufacturer directions for more information about how to remove the watch from the bracelet. Submerge it in a small bowl filled with soapy water or rubbing alcohol.  Soaking your watch bracelet in this way will loosen the grit and grime that it has accumulated.  The length of time you allow your watch to soak depends on how grimy it is.  If it is quite dirty, leave it submerged for a few hours. If it is not too dirty, leave it submerged for about 30 minutes. If your watch’s head doesn’t detach from the bracelet, wrap paper towel or plastic wrap around it, and bind it in place with string or a rubber band.  Alternately, take your watch to a jeweler for a professional cleaning. Dip a soft-bristled toothbrush in rubbing alcohol or soapy water.  Remove your bracelet from the liquid and use the toothbrush to gently scrub away discoloration or dirt that has collected within the gaps of the watch band. Some chemical cleaners contain benzene or similar substances that can ruin stainless steel.  They might also cause skin irritation, even when they’ve been cleaned off.  Therefore, stick to soapy water or rubbing alcohol when cleaning your stainless steel watch.
