Everything that is used without care tends to wear out over time, and even the strongest structures can suffer damage if not properly maintained. That’s why it's important to take good care of the things around us—especially doors and windows. Let’s explore some effective maintenance tips to keep them in top condition.
There are four key steps for daily maintenance of doors and windows:
First, avoid hanging heavy items on door panels or slamming them shut. Always open and close doors gently to prevent unnecessary stress on the hinges and frame. This helps maintain their functionality and extends their lifespan.
Second, never touch door locks with wet hands or spray corrosive chemicals onto wooden doors or locks. Be careful when turning the handle or opening the lock, and avoid applying too much force. If hardware like hinges or locks become loose, tighten them right away. If the lock isn’t working smoothly, you can apply a small amount of graphite powder or a suitable lubricant into the keyhole to restore its function.
Third, when cleaning glass, make sure cleaning solutions or water don’t get into the gaps between the glass and the bead. This can cause the bead to deform or loosen over time. Avoid scrubbing the glass too hard, as this may lead to cracks or scratches. If the glass is damaged, always seek professional help for repairs instead of trying to fix it yourself.
Fourth, for wooden doors, use a soft cloth or duster to remove dust and fingerprints. Avoid using rough materials that might scratch the surface. For stubborn stains, a mild detergent, toothpaste, or a specialized furniture cleaner can be used—but remember to wipe it off immediately after. Don’t rub the corners of the door frequently, as this can cause the finish to fade or peel. Regular cleaning and dusting will help keep your wooden doors looking new for longer. You can also use a quality wood polish to maintain their shine and durability.
A manhole cover is a removable plate that is used to cover the opening of a manhole, which is a hole in the ground that provides access to underground utility lines, such as sewer, water, or electrical systems. Manhole covers are typically made of cast iron or other durable materials to withstand heavy loads and prevent unauthorized access to the underground infrastructure. They are usually round in shape to prevent them from falling into the hole and are designed to be easily lifted and replaced by maintenance workers when necessary. Manhole covers are an essential component of urban infrastructure, ensuring the safety and functionality of underground utility systems.
