For the maintenance and cleaning of the wardrobe surface, we should try to avoid damaging and scratching the wardrobe surface during use. If there are slight scratches and abrasions on the surface, we can dip some cotton cloth in a mixture of soot and lemon juice or fried grain oil, dry it and wax it. If the scratch is deep or the bruise is serious, you need to blend the same color paint to make up the color, or go to the wardrobe store to buy a color supplement to repair it.
Regularly check the 3-in-1 connector between the back panel of the wardrobe and the laminated board, especially when severely impacted by external force. If looseness is found, fasten it in time and inject a small amount of lubricating oil to prevent rust and corrosion. If there is a problem during the second disassembly, you should promptly notify the store or manufacturer for help. Prevent external force or heavy objects from impacting the sliding rail and door panel of the whole wardrobe, push and pull gently, and don't push and bump at exorbitant profits.
