Daily cleaning of warehouse cages is not optional: oil buildup accelerates bottom rust, dust and swarf trapped in the mesh openings wear through the powder coat, and foreign matter mixed into the material causes product-quality incidents. We suggest a deep clean once a month and a visual inspection once a week.
Dust removal: blow dry dust off with a brush or compressed air, working from the inside out—don't blow back against the mesh and pack dust into the gaps. In workshops with lots of swarf, turn the cage upside down, tap it, then blow. Don't spray directly with a high-pressure water gun; water that gets into the hinges and bottom corners is very hard to dry.
Oil removal: the bottom of cages in machining workshops tends to collect cutting fluid and grease; scrub with a neutral detergent in warm water. For stubborn grime, spray metal cleaner and wait three minutes before scrubbing. Wipe dry after washing—especially the base frame and stacking feet must be wiped dry, not left to air-dry.
Foreign-matter removal: before every material change, check the cage for left-over bolts, swarf or offcuts, to keep them out of the next batch of product. Cages used for food or pharmaceutical materials should, after cleaning, be visually checked again for residual debris, and inspected by eye if necessary.
After cleaning, go over the welds and powder coat for cracks or peeling, and tag and report any issues promptly. Nanjing Tongnuo Warehouse Equipment Manufacturing Co., Ltd. advises customers to keep a cage-cleaning log, recording cleaning time and appearance condition by batch for traceability.
