# Restoration Diary: Super Famicom Controller Button Refresh
**Symptoms:** Buttons felt sticky and sometimes failed to respond during gameplay.
**What we did:**
- Opened the controller carefully, removed the rubber pads
- Cleaned conductive pads and PCB contacts with IPA and lint-free swabs
- Wiped shell inside and out with a soft cloth
- Reassembled and tested on a Super Famicom console
**Parts used:** Isopropyl alcohol, lint-free swabs, microfiber cloth, small screwdriver
**Result:** Buttons now respond crisply, no sticking or missed inputs.
**Warranty note:** Rubber pads remain original but refreshed; long-term wear depends on use.
