Country of manufacture: Japan Contents: 100ml x 2 bottles Main ingredient: Alkaline electrolyzed water Usable materials: Cleaning and deodorizing rubber bands such as gold, silver, platinum, carbon, ion plates of various colors, colored gold, titanium, stainless steel, chrome plating, etc. Unusable materials: aluminum, copper, brass, jewelry, natural stones, pearls, shells, leather, glass (if visible or cracked) As the name suggests, ``Wash Clock'' water for cleaning precious metals is water that thoroughly removes dirt from watch straps, accessories, etc. The watches and accessories you use on a daily basis become a breeding ground for bacteria due to sweat in the summer and dirt from your skin that is most likely to appear in the winter. If you leave it alone, it will start to stink. This Clock Washer instantly removes dirt and odors and makes it shine. Since it is water, it can penetrate into areas that creams and cloths cannot reach and remove dirt. It's also very easy to use. Place a tissue or cloth underneath, spray it on, and wipe it off after 20-30 seconds. As you can see in the image, the jet black sebum stains can be removed in large amounts according to the shape of the grooves on the belt. Due to the concentration, you can clean, deodorize, and sterilize all at once. In the case of watches, the amount used at one time is about 5 ml at most, so one bottle can be used to wash around 20 times. Please note that if you do not thoroughly wipe and dry the product after use, unwiped dirt may stick to your skin or clothing. Unlike conventional alkaline electrolyzed water, the alkaline electrolyzed water of this product has extremely low content of sodium, its compounds, and chloride ions. This reduces the impact on the human body and metals. It is clear that electrolyzed water that is produced over time has different properties from mass-produced electrolyzed water, so please use it with confidence.
