Method 1: Wash with alcohol and soap, wipe with a soft cloth dipped in soapy water in the hotel, and do not use particles such as toothpaste to avoid scratching the appearance. Scrubbing once a week will be extremely bright.

Method 2:? Soak in ammonia water. 18K gold necklace is dirty, then soak it in ammonia water for one night to wash away the dirt. Be careful that the concentration is not too high, so as not to corrode the protective film.

Method 3:? When the necklace is baked with alcohol lamp, white spots often appear on its appearance, mainly because some cosmetics containing tributes are used and stained on its surface. Tribute can be melted when it meets high temperature, and then it can be gently wiped with a soft cloth. ?

Method 4: You can dip the old toothbrush in neutral cleaning solution or commercially available jewelry cleaning solution, and gently brush the bottom of the base and the fine seam where the diamond is set, otherwise the gem will be eclipsed because of its overall transparency. ?

Maintenance: 18K gold necklace should be stored separately to avoid contact with chemicals, friction and collision with hard objects. Do not wear 18K gold necklace when doing housework or taking a bath. Because women need to wear makeup and perfume every day, they should pay special attention to it before wearing 18K gold necklace.

Just take it to the store and wash it. Very clean.
