What Causes Door Squeaking?

[DiAlexis]

Here are the specific reasons for door squeaking: 1. Door hinge wear: Wipe off surface dust with a cloth or tissue, then repeatedly apply a small amount of lubricating oil to the door hinge and the red-circled area of the door limiter using a cotton swab. Open and close the door repeatedly, repeating the steps of applying oil and operating the door until the squeaking disappears. Avoid applying too much lubricating oil to prevent contamination of other door parts. If the issue persists, it may be due to wear and tear, requiring replacement of new hinges and limiters. 2. Aging door seals: Check if the door seals are aging. Seals are rubber products, so regularly clean dust and rainwater from the gaps between the seals to prevent aging. Since sand and dust can easily accumulate in the gaps of the seals, use a brush to frequently clean the dust and then apply a layer of highly permeable protective agent to prevent seal aging. If the seals are severely damaged or significantly aged, they need to be replaced with new ones.
