Warning: While this worked for me, one person has reported that this contact cleaner (WD-40 Specialist Fast Drying Contact Cleaner) led to jammed keys for over 3 weeks. Do this at your own risk!
My OP-Z has been unusable recently due to double/multiple trigs, so I decided to try to fix the problem using contact cleaner, following advice from this Reddit thread. It works really well, I’m so pleased! I recorded the whole process outlining the problem and the solution as well as a quick modification to make the unit more stable. Hopefully it’s useful for someone facing similar issues!
FYI: I tried using the WD-40 “Specialist Contact Cleaner” I used about the same amount shown in the posted video. It seemed to work on a few buttons that had very bad double trigs. But it made several buttons stop working completely, unless you press down very hard the button will not trigger. I looked at the reddit post and found a link to the elektronauts. See below. In the elektron post it expressly says not to use WD-40 or other contact cleaners. “Only use deoxit D5” I have not used deoxit but from all of the material I have read, it seems like the way to go. regardless I hope my OP-Z eventually will start working after some time passes. BTW it has been 3 weeks with no improvment.
I’m sorry to hear that, it worked perfectly for mine, and a few people have contacted me that have used the same contact cleaner (WD-40 specialist fast drying contact cleaner) and it worked fine for them too. I imagine that the Elektronauts post is specifically meaning regular WD-40, the lubricating oil/water displacer, definitely don’t use that, as they specifically mentioned ones that are greasy. In the original Reddit post, the OP said:
The bad news? I used too much D5 and completely jammed a number of keys for almost 5 days.
I imagine it’s the same problem here, it could be that it just worked its way in quickly. Hopefully it dries out and releases the keys soon.
Worked perfectly for my OP-Z that had a couple of double-triggering keys that were bothering me. Put a couple of drops on those keys (easy with the needle applicator), pressed them 20/30 times, let the OP-Z rest a couple of hours, and it’s good as new.
worked perfectly, and had some other stuff to help me get a midi keyboard back up and running smooth.
As well as fix a finicky door ajar switch on my truck lol
I’ve been double trigger free for at least 6mo of weekly use, sometimes longer. I keep mine stored in the roll up bag inside a zippered pocket on my op-1 case, so hopefully it isn’t getting exposed to too much dust while it sits
Edit: the kit I link has changed. The one I used came with brush applicator bottles, not squeeze tubes.
