The secret of amber maintenance is as follows: 1. Amber ornaments are afraid of high temperature. Don't leave it in the sun or near the heater for a long time. It will crack easily if it is too dry. Try to avoid drastic fluctuations in temperature difference. Although Haiper has been immersed in seawater for thousands of years, amber is afraid of strong acids and alkalis. 3. Try not to touch alcohol, gasoline, kerosene and organic solutions such as nail polish, perfume, hair gel and pesticides containing alcohol. Please take off amber jewelry when wearing perfume or hair gel. 4. When amber is stained with dust and sweat, it can be soaked in warm water with neutral detergent, washed by hand, and then wiped clean with a soft cloth (such as glasses cloth). Finally, drop a small amount of olive oil or tea oil, gently wipe the amber surface, and then wipe off the excess oil stains with a cloth to restore luster. Amber jewelry should be stored separately, not with diamonds or other sharp or hard jewelry. Amber has low hardness and is afraid of falling and bumping. Friction with hard objects will make the surface rough and produce tiny marks. 7. Do not clean amber with hard objects such as brushes or toothbrushes. You can use warm toothpaste without abrasive particles to remove traces of amber. Use it with caution. 8. Don't use ultrasonic jewelry cleaning machine to clean amber, which may break amber. 9. Wipe with pure cotton cloth (glasses cloth) to restore amber luster to some extent. A more professional polishing method is to mix tooth powder with wax oil and rub and polish it back and forth while the mixture is still hot. The best maintenance is wearing it for a long time. Human oil can make amber brighter and brighter.
