What are the precautions for cleaning gold and silver jewelry?
What are the precautions for cleaning gold and silver jewelry? I summed it up. If the jewelry is worn for a long time, the surface will cover up the original flash due to oxidation or dirt accumulation. At this time, the jewelry will be taken to the jewelry processing shop for cleaning.
But it is precisely because of this that some unscrupulous operators will take advantage of the opportunity of cleaning to defraud customers of gold, resulting in customers' gold and silver jewelry cleaning being "slimmed down". What are the precautions for cleaning gold and silver jewelry? Let's see what kind of traps are hidden in the cleaning service.
Gold jewelry will "slim down" in the cleaning solution because some unscrupulous jewelry processors add nitric acid to the hydrochloric acid solution used. After high-temperature barbecue, gold will dissolve unconsciously after soaking in this corrosive solution for 20 minutes. This mixture of hydrochloric acid and nitric acid is called aqua regia. "Aqua regia" can dissolve precious metals such as gold and platinum, and release gold element, and these "aqua regia" dissolved with gold element can reduce the gold dissolved in "aqua regia" through simple chemical reaction and adding active metals.
Prevention of "slimming" gold and silver jewelry cleaning scam is relatively hidden, and many times customers will not notice it themselves, so attention should be paid to prevention when cleaning precious jewelry:
First, choose a regular jewelry store. Some places with large scale and good reputation are safer. You can also check the qualification certificate and business license of the jewelry store.
Second, weigh your jewelry accurately before cleaning and record it; When cleaning jewelry, smell the cleaning liquid. If there is a pungent smell in the solution, it is "aqua regia", so be careful. After processing, go to other departments to weigh again in time.
The third is to ask for bills when paying fees after cleaning. Once the operator is found to be fraudulent, he should report it to the relevant departments in time.
