Wash Clock Precious Metal Cleaning Water Purchased for cleaning a Rolex metal band, used about 50%. The box has a slight dent. Please understand that this is a used item. No price reduction. May be delivered in recycled packaging. --- The following is the Amazon product description --- "Wash Clock" precious metal cleaning water, as the name suggests, is a water that thoroughly removes dirt from watch bands and accessories. Watches and accessories you use daily become breeding grounds for bacteria due to sweat in the summer and sebum in the winter. If you leave this unattended, they will start to smell. "Wash Clock" instantly removes such dirt and odors, making them sparkling clean. Since it's water, it penetrates into areas that creams and cloths can't reach, removing dirt. It's super easy to use. Just place a tissue or cloth underneath, spray it on, wait 20-30 seconds, and wipe it off thoroughly. As you can see in the image, the black sebum dirt comes off completely, conforming to the shape of the band's grooves. Due to the concentration, it can clean, deodorize, and disinfect all at once. For watches, the amount used at one time is about 5ml at most, so one bottle can be used for cleaning around 20 times. Be careful, as dirt that hasn't been wiped off may stick to your skin or clothing if you don't wipe it off thoroughly and dry it after use. ---
