Sealed storage box+moisture-proof desiccant

"For ordinary consumer digital cameras, another practical moisture-proof method is sealed storage box+moisture-proof desiccant." Sealed storage boxes can be bought in supermarkets in general, and the sealing rubber strip at the sealing part of the box can effectively prevent moisture from invading. The color-changing silica gel produced by Bishui Longyue Environmental Protection Company is the most commonly used moisture-proof desiccant for photography enthusiasts. It is blue when it is dry and pink when it is wet. Put the wet silica gel in the sun or bake it in the microwave oven, and it can be used repeatedly after it becomes blue. When storing photographic equipment, just put the color-changing silica gel at the bottom of the sealed box, spread a clean white cloth as an isolation layer, and in principle, do not let photographic equipment directly contact the color-changing silica gel, and then seal the box cover.

Moistureproof box is the safest.

"Enthusiasts with consumption power suggest adopting a more secure moisture-proof method, that is, using a special moistureproof box, which costs from several hundred yuan to several thousand yuan." According to professionals, ordinary sealed moistureproof box is mostly made of high-strength plastic or rubber. The box is generally equipped with a hygrometer, a rubber sealing ring at the lid, a pressure regulating valve at the top, and an internal moisture absorption device, such as a moisture absorption card, which can be recharged and heated to restore the dry state for repeated use; Electronic moistureproof box can use dehumidifier or memory alloy to put it in a closed storage space.
