Unlike watches that feature metal bracelets, the soft plastic straps and outer casing of Casio's white Baby-G watches are liable to turn yellow due to dirt and ageing. Thankfully, there are several ways you can return your Baby-G watch to its former glory without spending a small fortune on specialist cleaning products or professional watch repair service.
Dip the small paintbrush in the hydrogen peroxide mix (three percent), coat the watch with the fluid and leave it to dry for 24 hours. Wet the soft cloth in the warm soapy water and clean the band. If the watch is still slightly yellow, repeat this step.
Dab a small amount of lighter fluid on your soft cloth and quickly wipe the watch. Wet another part of the cloth with warm soapy water and wipe the watch again to avoid the lighter fluid from corroding the plastic.
Rub softly the yellow stains with the fine grain sandpaper to remove the top layer of plastic.
