How to lubricate without lubricating oil at home?

1. Lard and various animal oils can be used at home, which is a good substitute for lubricating fluid and has a wide range of uses.

You can use soap instead of lubricant at home. For example, the furniture used, especially wooden furniture, will have astringency when touched by hand, and the astringency will disappear immediately after being coated with soap.

3. Red wax can be used instead of lubricant at home, for example, the zipper of clothes is difficult to unzip. After painting, the zipper can be unzipped freely.
