(1) When moving the metal zipper, please be careful not to put garbage such as collars and selvedges into the metal zipper, so as to avoid the occurrence of skewed teeth, broken abdomen, and tooth loss. When the metal zipper is astringent and difficult to pull, please do not pull it forcefully. Apply wax or soap to metal zippers.
(2) If the teeth on one side of the metal zipper head are branched, worn and loose, you can use pliers to gently clamp the closed end of the metal zipper head laterally, the metal zipper will soon become better, and the teeth on one side will be tight and not loose . Avoid contact with wet environments. Part of the teeth of the metal zipper are blackened due to metal oxidation.
(3) Avoid contact between the metal fastener and the rubber band, because the rubber band itself contains sulfide, when the metal fastener is bound with the rubber band, the metal chain teeth will vulcanize and turn black). After washing, it must be washed and dried immediately: dyes and residual chemicals in the fabric undergo redox reactions with metal parts, which may discolor.
The above are the precautions and maintenance methods for the use of metal zippers. Only we do daily maintenance and pay attention when using them. It will bring greater convenience to our lives. I hope everyone can pay attention to it!
