Which chemicals are most likely to damage the watch

Watches in daily use, if exposed to certain chemicals, may cause damage to it. Here are some of the most damaging chemicals for watches:

Corrosive acids, alkalis, salts, such as sulfuric acid, hydrochloric acid, etc., these strong acids are strongly corrosive and can quickly erode the metal parts of the watch, resulting in corrosion, discoloration and even perforation of parts such as the case and strap. Alkali such as sodium hydroxide, potassium hydroxide, etc., is also strongly corrosive, and will cause serious damage to the coating and metal parts of the watch. Although common salt is less directly corrosive to the watch, the salt in sea water (mainly sodium chloride) and some industrial salts are strongly corrosive to metals, and long-term contact may cause the watch to rust or the coating to fall off.

Organic solvents such as gasoline, alcohol, these organic solvents can dissolve the grease and protective layer on the surface of the watch, resulting in material damage to the strap, case and other components, discoloration, cracking and other problems. Paints and coatings contain a large number of organic solvents and pigments, if accidentally splashed on the watch, may penetrate into the case or inside the watch band, causing difficult to remove stains and corrosion.

The chemicals in cosmetics are complex, and some contain acidic or alkaline substances, as well as additives that can cause damage to the material of the watch. Therefore, cosmetics should be avoided when touching the watch. The gas and liquid components of the spray can also cause damage to the watch, especially if the spray contains corrosive substances or organic solvents.

The aqueous solvents of pesticides and pharmaceuticals may contain a variety of chemicals, some of which may be corrosive to materials such as metals or plastics. Therefore, in contact with these items should try to avoid letting the watch contact.

The mercury released after the thermometer is broken has a strong corrosive effect on metals, and if the watch is accidentally exposed to mercury, it may cause serious damage to the watch case, watch band and other components.

In order to protect the watch from damage, it should try to avoid its exposure to the above chemicals. If accidentally exposed to these substances, should be immediately washed with water, and as soon as possible to a professional watch repair shop for inspection and repair
