I wanted it to work on the air conditioning buttons of a 2004 Corolla. It did nothing. In fact, because it has no oil and dries quickly, the button with the frame, when it dried after a few minutes, I couldn't press it. I had to take a thin razor to pry it off. I tried a cheaper contact spray for 3.10 euros, and after persistent use for 3-4 days on one button, spraying a little 2-3 times a day, it became functional. For the other two, with the first application and spraying 2-3 times, they also became functional. I was amazed by the effectiveness of MORRIS contact spray at 3.10 euros. I regret the 8.5 euros spent on WD-40, disappointing with the final result because I didn't expect it to do nothing for what I wanted. My rating is for this specific task I wanted, and for a TV remote that also did nothing, until I found a solution and applied how to clean a TV remote without spray, and it became functional like new. On YouTube, check out DIMAKIS solutions for TV remotes if you want. The reason is to try cheaper economic solutions as I described for your problems. If you are not satisfied, then if you want, try the WD-40 contact spray.
