Hosa 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

I have a 09 yukon xl denali and the heated seat button (the one that does back and butt) was not working. I couldn't find a replacement button for under $100. Chat gpt actually recommended I try this spray. I sprayed a bit around the buttons and pressed it about 20 times, let it dry for a few minutes, turned the car on and.... nothing it didn't work. The next day I pushed the button again and it has been working flawlessly! Definitely recommend this spray, saved me a hundred bucks and an hour of taking my truck door apart. Excellent product! Just give it a chance to fully dry.

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!

This stuff really works great on removing the yuk from exploded batteries, or grease or other things that build up on contacts. THey also clean circuit boards too. This is high end cleaner and worth the price.

This contact cleaner is truly remarkable! It works wonders by swiftly enhancing connectivity in scratchy pots, switches, and jacks. The 5% DeoxIT solution is both potent and gentle, while the spray applicator ensures precise application. A necessary tool for maintaining audio equipment, guitars, and electronics. It's dependable, long-lasting, and definitely worth the investment. I first learned about it from a magazine called Audio Amateur, where a similar product named Cramolin was featured. Like DeoxIT, Cramolin also had red and blue variations. The blue was designed as a preservative for new contacts, while the red served as a cleaner and preservative for oxidized contacts. Theoretically, the blue may offer superior long-term protection, whereas the red excels at cleaning and restoring already oxidized contacts. Highly recommended for maintenance and repairs!

I've used one form or another of this product since the mid '70s and it's fantastic. I'd found out about it from a magazine back then called Audio Amateur and at that time, the similar product was called Cramolin. As with DeoxIT, it came in a red and a blue variety. The blue is/was a preservative for newly manufactured contacts and the red is/was a cleaner and preservative. Theoretically, the blue may provide longer/better protection while the red is better for cleaning and restoring contacts which are already oxidized. You can clean contacts with the red, then remove it, then treat with the blue to get the best protection of already oxidized contacts, but in practice, the red alone works so well that it's extremely effective to simply clean and treat the contacts in one step using only the red. As a result, I use about one can of blue for every ten or more cans of the red. For most uses, most folks only need the red (D) variety. I don't want that to make it sound like I go through cans and cans of the stuff, but since I work in the electronics field, I do use a lot more than most people. As has been mentioned in several other reviews, you need very little of it to do most jobs. A single can will last a very long time even for someone who is constantly working on a lot of equipment. After finding out how well it worked on audio connections and potentiometers, I introduced the folks at the electronics company where I worked to it. All of the technicians and engineers were amazed and it soon became a staple. We designed, manufactured, installed, and serviced various telemetry and process control equipment. A lot of this gear as well as equipment made by others that we were called upon to service was in areas with corrosive atmospheres like oilfield, refinery, water/wastewater treatment, laboratory, and other locations where hydrogen sulfide, chlorine, hydrochloric acid fumes, etc., are present, leading to lots of contact-related problems. It's been extremely effective over these many years, and although the name and formula has changed since the "Cramolin" days, the new stuff seems to still be very good. I've also used it on very high voltage connectors and one of the amazing properties of it is that while it improves contact integrity and lowers contact resistance dramatically, it does not break down and cause leakage or flashover when used on high voltage systems. I've used it for years on photomultiplier tube and Geiger tube devices (radiation survey and monitoring equipment), and never had any problems with it. These systems usually operate with bias voltages between 900 and 1500 Volts, but sometimes run up to 2500V. A fantastic example of how it works was something we did many years ago where we had a batch of very old thermal self-resetting circuit breaker devices in a system. The problem was that they had silver contacts. Silver itself is the best conductor of all elements, but it is very reactive and oxidizes (tarnishes) very easily. These devices were sealed and "non-repairable". But their contact resistance was unacceptably high. I mixed a solution of Cramolin Red and a solvent (probably Freon TF back in those days), put it in a glass jar, and simply dropped these breakers into it and kept them submerged until the bubbles stopped coming out to make sure they were totally flooded with the solution. We then took them out, letting the fluid run back out of them, and then rapped them on a desk a dozen times or so to make the contacts inside "jiggle" a bit. That was enough to let the Cramolin work its way between the closed contacts. Measuring a number of these breakers before and after the treatment, the resistances started out between 100 and 200 milliohms. After treating them, the typical resistance went down to around 6 milliohms! The high current and low voltage these devices needed to carry meant that the voltage drops across them had been unacceptably high, but post-treatment, they operated beautifully. And stayed that way for years. Various other contacts which would heat up and cause other problems prior to treatment operated cool and with extremely low voltage drops after treatment. I've personally "repaired" countless potentiometers, switches, and various connectors over the years with this stuff. We call it "Technician in a Can", and it lives up to that name. I pre-treat a LOT of contacts prior to crimping them onto their wires, and it lowers the mating forces and improves the reliability of virtually any connector. It truly is special stuff. It's indispensable for technicians, manufacturers, audiophiles, etc. If I had a 55 gallon drum of it, I could take entire pre-amps and other audio gear and dunk it to fix all of the bad switch contacts and pots in one quick operation. :) The only thing that's a minor issue is that as with any contact cleaner that has (or is nothing but) a solvent, it will flush away the viscous goo that's often used to make a potentiometer have a "silky" feel to it when rotating. So when you're treating a pot, it's best to try not to allow any to get to the shaft/bushing part of the pot if you want to preserve the grease that's in that annulus. But it often totally fixes a "scratchy" pot by simply getting it on the resistive pad and then running the pot back and forth a dozen times or so. As with so many things, for some reason, manufacturers just love to make pot wipers with silver plating. Bad idea! But all too common. Once that wiper tarnishes, the pot will sound awful since silver oxide is an insulator. The DeoxIT usually allows that oxide layer to be removed by simply rotating the pot a dozen times or so, and then it coats the wiper and the resistive element, preventing future problems and leaving the pot working/sounding excellent. Anyhow, all I can say is that this product has served me extremely well for nearly 40 years, and I highly recommend it.

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.

This product saved two of my neglected guitar amplifiers. as pictured, I put a tube of clear hose that fits tightly over the thread then squirted this wonder juice while using a screwdriver to move back and forth, I could feel the potentiometer getting free and easy moving, doing all 10 dials then with compressed air blowing out any moisture crossed my fingers and WOW now the amp works perfectly no scratchy noise! for good measure I cleaned the plug-in with cotton swab

I first encountered Deoxit when editing a music magazine. The distributing company sent out a sample kit. I promptly took it home and attacked my old NAD 2020, a Norwegian designed and Chinese built integrated amp for our stereo system, vintage....1976 no less. I'd pushed the NAD aside for a couple of years because every single pot, knob, any moving object that adjusted the sound had gone terribly bad. The loud rude noises and fire cracker crackles sometimes got the dog jumping from his repose on the couch. With one treatment with spray and some wipes, and not having to go inside the unit....did it all from the outside....it totally cleared up all the problems: made pots, knobs, sliders, etc, easy to set in motion. Eliminated completely any noise: snap, crackles, pops. Completely. Only recently, ten years later, has one of the knobs exhibited any noise. You spend a little more on Deoxit but it saves you big time. The next occasion was a few weeks ago and purchasing the Hosa Deoxit spray from Amazon.ca for a problem in my home studio. Similar results, perhaps not as dramatic, but the deal is this: it cleans and clears anything out of the way of the audio signal path. With no impediments, no sludge or oxidized soldering jobs, connections, etc the result is better, fuller, clearer sound devoid of those snaps, crackles, etc. Follow directions. Do not use and operate a motor vehicle. Seeing if you're alert. Tbw

I thoroughly read the customer's reviews. One by one. It was crucial to be sure the product won't affect wrongly my Akai Receiver AA-R30, which has been working for us more than 45 years. Our technician was excited to test the DeoxIt-2 Contact spray. He and us are so delighted to enjoy back again our Receiver. We recommend and appreciate this product so much! The seller was very efficient too, dispatching the package the same day! We are truly greatful, my sincerest thanks !!! David S.

Rated by the industry for reviving and cleaning dirty potentiometers or scratchy faders, and any other bad-contacts/switches. This has been the cheapest price i've found online but it is still quite expensive for what it is. Not sure if we are paying for a magic formula or the name. Perhaps there are cheaper alternatives out there but trial and error testing the competition may not be a cost effective experiment.

Es un producto de excelente calidad.
