it made all the potentiometers of an old stereo amplifier, which hadn't worked for over ten years, work perfectly without the slightest "scratch"

I removed the steering switch for the indicators, lights, and such because they stopped working.. I sprayed well through holes and openings with plenty of spray, blew it well and left it for about three hours to be sure it dried well! The switch now works perfectly

This is the new name of Morris Contact Cleaner, and it was purchased on 15/06/25.
With €4.00 it revived in a few hours the completely dead touchpad (and its 2 buttons) of a worn-out Dell 7480.
Product lifespan 10 years!
(Maybe I even got a collectible piece that will be produced 3 months after I bought it...!)

For its price, it's very honest.. I needed it for the 2004 Corolla; half of the contact buttons on the dashboard were not working.. and everything was fixed.. of course, it requires patience; it takes 2 to 3 applications until it dries.. by the 3rd day, everything was fine..

The promotional gas ran out while the package was half full! If it happens to me again, I will remove a star; if not, I will add one. This has never happened to me with WD40.

I used it for control from a mattress blanket, it immediately caught the paddles, and I mean the blanket was for throwing away because it looked like the controls weren't working, now it works and continues relentlessly just with a spray of this.

Miraculous! Like the friend above, I also got it because the buttons on the car's air conditioning were not responding. Caution: don't rush to see results immediately. Let it work for several hours (not just 15' as stated on the package). I left it for 24 hours and the next day everything was working normally!

I cleaned the contacts of a sound system for the computer and the result really surprised me; it completely stopped the issue I had with the sound

I don't like its spray at all. It shoots with great pressure and not widely, but at a small angle, resulting in a large amount falling in one spot. Personally, it didn't work for me at all because I wanted to use it for restoring plastic surfaces in a car.

I have revived a pressure gauge that didn't work, 2 TV remote controls where half the buttons didn't work, and we'll see what else in the future .... it was worth every penny and more. It just needs a little patience while drying.

For contacts only, I suppose, because it leaves a lot of white residue, and I have seen better results from more expensive ones, but the price is good.

I did my job, I cleaned what I wanted. HOWEVER.... I hadn't noticed that it says on the box that it needs at least 15 minutes to dry. So, I ended up with a car plug filled with cleaning liquid that wouldn't dry. It had sprayed too much liquid and it wouldn't evaporate. I had to blow it and wait 15-20 minutes for it to dry to make sure I could plug it back in. This makes it inconvenient. However, it is a good price and it did the job.

It does what it promises. So far, I haven't encountered any issues when applying it to cables and electrical contacts. It dries quickly without leaving any residue or dirt. It also sprays strongly and with pressure. The quantity at this price is good. Value for money purchase.

It does its job just fine. It does what it says: cleans electronic contacts. Of course, don't expect it to "save" your phone if it fell into the sea. It doesn't perform resurrections.

One of the best on the market! Plenty of pressure, leaves no residue, cleans. All these things you want it to do, basically!!

I use it for cleaning dust residues and dried thermal paste on computers. It can only be compared to the amazing EC-90, which comes at triple the price. Excellent cleaning, dissolves dried pastes directly, dries quickly, and leaves no residue. It is safe because it is non-conductive and does not leave a strong odor for anyone who might be interested. Highly recommended for this use.

In an old power supply internal antenna that couldn't catch anything and was for throwing away, I sprayed switches, contacts, and the rotating regulator, and it works perfectly. In radios where the volume setting scratches, it was fixed. Switches, old elevator buttons, everything works perfectly! If it falls on other moving parts, they need lubrication because it dehydrates them. That's its job, to remove grease, salts, residues, and oxidations.

It has been tested on the faders of an analog Behringer sound console and while it fixed the crackling caused by dust and dirt that had gotten inside, it also removed the lubricant inside the faders and now they stick quite a bit.
Maybe it would be better to get another one with oil and after using this one, apply a little bit of oil.
Also, it has a very small brush (about 3cm) so this might make it a bit difficult for you.
Other than that, it's an excellent product. It did what I wanted and at a very good price.
