What kind of oil should be used for door squeaking?
2 Answers
For door squeaking, use WD40 lubricating oil. Below is an introduction to the relevant content: 1. Lubricating oil: Lubricating oil is a liquid or semi-solid lubricant used in various types of automobiles and mechanical equipment to reduce friction and protect machinery and processed parts. It generally consists of two parts: base oil and additives. 2. Function: Lubricating oil is a technology-intensive product and a complex mixture of hydrocarbons. It mainly plays the roles of lubrication, cooling, rust prevention, cleaning, sealing, and buffering. When the lubricating oil flows to the friction area, it adheres to the friction surface to form an oil film, reducing the resistance between friction components. The strength and toughness of the oil film are the keys to its lubricating effect.
I once encountered a squeaky car door and felt quite accomplished solving it myself. Initially, I sprayed some WD-40, and the noise stopped immediately, but it returned when the weather got humid because WD-40 evaporates quickly and isn’t a long-term solution. After researching, I found that silicone-based grease, like the white or transparent silicone products specifically for door hinges, works best—it resists moisture, doesn’t attract dust, and provides long-lasting lubrication. When applying, first clean the door hinge, wiping away old grease, dust, and dirt with a cloth, then apply a thin layer of grease while testing the door by opening and closing it. Also, pay attention to the source of the noise: it could be due to rusted hinges, aging or loose door seals—check those areas for cracks or looseness while you’re at it. Regular maintenance like this can prevent many minor issues, saving money and giving peace of mind.
