Ahh the Internet, what a wonderful place of conflicting information!
About an hour of reading forum posts and watching videos, and I'm still not sure what the best way is to clean the #potmeters of our #Sennheiser #HDR120 wireless #headphones. They crackle and one of the sides cuts out completely at times.
Solutions I've seen:
- 2 drops of isopropyl alcohol in the square hole of the #potentioMeter
- WD40 (seems like a bad idea)
- #contactCleaner inside, or underneath
- #DeOxit with lubricant.
