1, special cleaner for gold
Because gold necklaces are generally exposed when worn, dirt will inevitably accumulate in the ditch, which greatly affects the wearing effect. At this time, they need to be cleaned. There is a special cleaning agent for selling gold in the market, which will not damage the surface of the gold necklace. Soak the gold necklace to be cleaned in water 15-30 minutes, then brush the dirty place with a jewelry brush, clean it and dry it.
Step 2 use toothpaste
If you don't have a ready-made special cleaner for gold ornaments at home, you can use the necessary toothpaste made of local materials, or soak the gold necklace in water for a few minutes, then squeeze a little toothpaste on the jewelry brush and gently rub the dirt on the gold necklace until it dissolves in water. If there is no jewelry brush, you can also use a soft brush.
Use alcohol
Gently wipe the dirty place on the surface of the gold necklace with a soft cotton cloth dipped in alcohol, which can also remove dirt. If the gap can't be wiped off with cotton cloth, you can also use a soft brush. Pay attention to choose soft cloth or brush, otherwise it will damage the surface of gold jewelry.
Step 4 use baking soda
Mix a small amount of salt with baking soda, pour it into warm water, and then soak the gold necklace that needs cleaning in water for two hours. When it is taken out, the gold necklace will be as clean as new. If dirt remains, you can brush it manually and dry it with a soft cloth.
5. Clean the instrument with ultrasonic wave.
This method can free your hands, that is, clean the gold necklace with the help of the machine. There are many kinds of ultrasonic instruments for cleaning gold jewelry in the market. You just need to pour clean water, put the gold necklace in, turn on the machine and wait for a few minutes, and it will be cleaned in five minutes.
