Wet a soft cloth and apply a few drops of mild detergent to the cloth.
When you wear a watch every single day, it is exposed to all sorts of elements such as the sweat from your skin, lotions, sunscreen and chlorine. Although Casio watches are higher quality, the resin bands of their white Baby-G series watches have been known to become discolored over time. If this happens, clean the watch yourself using basic cleaning materials found around your home. If you find the marks are too difficult to clean off, contact Casio to see about having them send you a replacement watch.
Rub the soapy cloth in a circular motion over the discolored areas of the watch band. Put more pressure to clean off any stubborn spots.
Rinse the watch off entirely to see if you need to take further action. If there are a few dirty or discolored areas, mix a bit of baking soda with water until it forms a paste.
Put the cloth over your finger and dip it in the baking soda mixture. Rub the cloth in a circular motion over the discolored areas and then rinse the watch clean.
