Cleaning and maintenance of hinges
1. Basic cleaning method: only use soft rags
Very simple and the most basic cleaning method is to immediately wipe with a soft rag, without adding any cleaning fluid and other compounds, or even water, just wipe with a soft rag. This method is suitable for applications where the pages are neater and there is no difficult-to-remove dirt.
2. Upgrade cleaning method: cleaning fluid plus grease
Add some cleaning solution to the towel, and then clean the hinges. After cleaning, add appropriate lubricant to the hinge for maintenance to make the hinge run more smoothly.
