How to repair a loose toilet seat after prolonged use?

Repair methods for a loose toilet seat after prolonged use:

1. Check and tighten the hinges: First, check if the hinge screws are loose. If necessary, use a screwdriver to tighten them. If it is a snap-on hinge, remove it and re-snap it to ensure it is properly engaged.

2. Replace worn or aged parts: For cases where internal springs, dampers, or plastic clips are worn or broken, it is recommended to replace the entire hinge assembly to restore stable opening and closing.

3. Re-secure the connection between the seat and the toilet: Check the mounting brackets or clips on both sides of the seat to ensure they are fully embedded in the toilet's mounting holes. If necessary, add anti-slip pads to the slots or use a suitable amount of adhesive to improve stability.

4. Lubrication and daily maintenance: Use a small amount of silicone-based lubricant to lubricate the hinges to reduce friction and noise. Avoid using oil-based lubricants, as dust accumulation can cause jamming.
