Video tutorial for fixing double trigs on OP-Z

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!


Thanks for posting this!

tip-top, thank you!


Nice. I’ve been putting off doing this because, like you, I found the recommended Deoxit cleaner prohibitively expensive in the UK. I’ve just ordered some WD-40 contact cleaner.

In my experience, not all contact cleaners work. I tried a different one before and it only made things worse.


What was the contact cleaner you used? It’d be good to post it so that people can avoid using it.

If the problem with double triggers are dirty contacts, does it make sense that totally fresh new OP-Z has double triggers problem too (oxidation without vacuum package wrapping may be)?

Yeah, it could be that it’s been sitting in stock a while or maybe it’s a problem with the manufacturing process. Mine definitely got worse over time though.

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.

I agree… It seems like a lot of people have been successful with this method. I am hoping it will eventually it will start working again. Thank you for the input!

I added a warning to the video title with details about your experience in the description. Please let me know if this does resolve itself.

Thanks to this thread, I bought some Deoxit in this format: CAIG Laboratories D100L-25C Contact Cleaner - that’s the one with the needle tip (see )

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.

For those of you that have done this - does it still work? Or did the effect die off?

I have used this kit successfully

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 :sweat_smile:

Edit: the kit I link has changed. The one I used came with brush applicator bottles, not squeeze tubes.

I’ve only done it once and my OP-Z is still much better. I do get an occasional double trig, but it’s very rare.

oh man I wish I watched this again before just using the straw that came with the thing and just liberally soaking the whole thing what a nightmare I think I ruined it

It’ll dry out, hopefully you worked it into the buttons nicely. It could take a week for it to fully dry if fully soaked like that, from what I hear
