What lubricant to use for a stiff car door?
1 Answers
Use grease (butter) for lubrication, but be careful not to apply too much to avoid attracting excessive dirt. Below is relevant information about grease: 1. Overview: Grease is a thick, semi-solid lubricant. It is used on the friction parts of machinery to provide lubrication and sealing. It is also applied to metal surfaces to fill gaps and prevent rust. It is primarily composed of mineral oil (or synthetic lubricating oil) and a thickening agent. 2. Types: Based on the thickening agent, grease can be divided into two categories: soap-based and non-soap-based. Soap-based grease commonly uses metal soaps such as lithium, sodium, calcium, aluminum, and zinc, as well as potassium, barium, lead, and manganese. Non-soap-based grease uses materials like graphite, carbon black, or asbestos as thickening agents.
