Hosa CAIG Laboratories D5S-6 CAIG DeoxIT Contact Cleaner, 5 Spray, 5 Oz

Stopped scratchy volume knob on a few radios, helped connections on a few auto computers, cleaned connections for better contact. A good product that is not a bathroom deodorizer so smell is irrelevant. You want a product that works and this does the job and in my experience will not harm electronics. As for safety if you have to ask what its for then maybe you should not be using it. Cant fix ignorance, LOL

Excellent product, cleaned And removed buildups on my 40 year old stereo receiver controls.

Amazing product! I used this on a fuse box and computer module that had been getting repeatedly wet on a 2008 BMW 328I that had been sitting for 2 years. When sprayed on the corroded terminals, it foamed up and seemed to virtually remove all of the white corrosion that had formed. Also, it seemed to leave a light oil residue that I'll bet will prevent future corrosion. I'm sold on this stuff and it is well worth the $15-$20 for a small can. Very impressed!

Made my old receiver sound like new! My old Sony Receiver was sounding terrible. The volume and balance knobs had a lot of static and weren’t adjusting correctly and I really thought the receiver was just too old to fix. I happened to read a few reviews about this cleaner and figured I would give it a try before I shopped around for another vintage receiver. When it arrived today, I simply removed the cover to expose the inside and located each knob from the inside and just sprayed a little on each location and turned each knob back and forth a few times. I let the cleaner dry for a few minutes and reinstalled the cover. I turned it on and could not believe how good it sounded. I absolutely cannot believe that this completely fixed my receiver. It sounds as good as new and couldn’t be happier. You have got to try this on your vintage electronics. You will not be disappointed.

Great product, but lousy packaging. The cap was surprisingly difficult to remove, almost to the point of crushing the plastic. The spray straw didn't fit the nozzle. I had to ream the nozzle hole and scrape down the end of the straw to insert it into the spray nozzle. Way too big of a hassle. The product worked well and saved me from replacing a switch that was intermittent.

This stuff is amazing. We use it for electrical connections on our Peterbilts and other electronics. I've seen this solve signal issues on can-bus systems and ABS systems with using nothing else. I don't know how it works but it does. I will caution to keep it away from certain rubbers. I've seen it swell o-rings used on our ABS sensor connectors but that's the only issue I've ever had with it. It's expensive for what you get but a little goes a long ways and it actually works unlike some other snake oils out there. Highly recommend giving it a shot. It's also great for 7-way plugs that are acting up. If you have a plug cleaner brush and this stuff its even better.

Amazing, frankly. I don't know how it does it, but you don't even have to have great access to the switch or potentiometer you're cleaning. On my guitar amp I was able to just spray it under the knob and roll it back and forth a few times and it still penetrated into the electronics and fixed the crackle i was getting.

Used this on a cable connector that ran inside a storage compartment on a motorhome. Over time, there was a bit of corrosion that built up and was not able to be cleaned off using other methods. This got rid of it and worked fantastic. You can see it working after spraying it on the contacts that need cleaning.
