Zenith's chemists developed this unique Non-ammoniated cleaner - without the ammonia or fumes. Product 251NA is called the "Gentle Cleaner" because it will not dissolve or react with watch and clock parts and cases that are coated with shellac, varnish or lacquer. Ideal for antique watches and clocks. Mix 1 part of Non-ammoniated 251NA with 7 parts of water to make 8 gallons of cleaning solution. It can also break the bond between hardened debris on metal watch and clock parts.
