2133 QD Plastic Safe Liquid Contact Cleaner, 14 fl oz Non-Aerosol Spray Can, Clear

I bought this because I had an intermittent connection on a slide switch in my Sansui AU-717 amplifier. Two or three shots did the job. The straw allows an easy reach into the slide past the flexible gasket; be sure to slide the switch and hit both ends. Full 1979 fidelity restored. I have always trusted CRC products. So, I tried a new use. I cleaned the plastic eye pads on my glasses. After struggling to remove the tiny screw and wash one pad, I hit it with the QD cleaner. Wow! Clean again. I hit the other pad without removing the screw; success! I used it on my wife's glasses; also successful. As promised, the CRC QD cleaner was completely safe on the pads and polycarbonate lenses. I highly recommend CRC QD Contact Cleaner. It is both safe and effective.

CRC makes good quality products and this is one. I repair/restore audio-video equipment and this cleaner comes in handy. It is no replacement for cleaning electrical parts that need physical cleaning, especially due to corrosion, rust or dirt, but in some cases where a component is sealed or not designed to be disassembled, this stuff is often the cure for noisy potentiometers and other parts where contacts are hard to get to. Many controls that rotate, have flip or push button switches can be made to work better if you can get this contact cleaner to where the contacts need cleaning. I find this CRC product just as good as other brands costing a lot more. Don't lose the plastic nozzle; you really want to pinpoint where you spray this stuff.

Okay. So I had a push button control for one of the rear heated captain's chairs in my Hyundai Palisade that was "sticking" in the down position. This push button should pop back up after each time it is pressed, cycling between High, Medium, Low, and Off settings with successive button presses. So I found a video online where a similar problem was fixed with a little spritz of electronic contact cleaner. My vehicle is under warranty, but when I considered the time and fuel I would expend taking this to the dealer (45 minutes driving one way from my home up on the mountain), I realized that purchasing this contact cleaner might actually save me money. I assumed the techician at the dealer would probably fix this by using contact cleaner like this anyway. So I rolled the dice. A tiny spritz of this CRC contact cleaner and a couple button presses completely solved the "sticking" of this switch. The switch button, surround, and nearby display are all plastic; Some of these plastics are black, others are clear, and some have decals or painted labels. The entire rear passenger control panel is surrounded by cream colored leather. None of these surfaces were discolored, harmed, or changed by this contact cleaner. The product description says this contact cleaner is safe on plastic and this is absolutely true. I have also used this product to clean out exploded alkaline battery gunk from inside a laser level and a grilling meat thermometer, both of which were no longer working. I was able to restore both of these devices to full function with a thorough cleaning with this CRC contact cleaner. Both items were plastic and again, the appearance of my laser level and my thermometer were not changed one bit (other than both look completely fresh and clean now). This can of CRC spray contact cleaner has already paid for itself many times over. Very handy product to have in your shop.

Working well.

Had issues with the seat belt buckle switch on a 06 Ridgeline. Was turning SRS light on. I sprayed this in to the buckle a few times and light when away. Can has more than what you need, doesn’t effect the color of plastic trim nor smells strong. Has been a few months and can still holds pressure but I don’t think I would be needing the rest. Price is way cheaper than having to replace seatbelt at a dealer, worked after 3 spray treatments.

I've been using CRC brake cleaner for years. It just works well. I cant even say I've tried a bunch of other brands because I KNOW this works, so why shop around.

This is my "go to" cleaner for any electrical contact cleaning. It is plastic safe (yes I found out the hard way, some other electrical cleaners are death to plastic). I used one can of this cleaner purchased at a specialty store over the last few years. Most frequent use is for cleaning battery contacts in AAA flash lights (those 3 AAA plastic cages) when the batteries go bad and corrode everything. Just scrape or wipe the worst of it away, then spray the surfaces to clean without fear that the electronics and plastics will be damaged. Wipe surfaces and repeat as necessary. Next biggest use has been for same problem with remote controls and cleaning battery contacts in my solar garden lights.. I use this for automotive electrical issues with connectors, bulbs, switches, relays -- basically anything electrical that has a problem caused by corrosion. I have been having trouble finding this EXACT "CRC QD Plastic Safe Liquid Contact Cleaner" -- it's not the same as "CRC Electronics cleaner" (I checked the CRC website) which is available lots of places. Glad to see AMAZON selling it and at a lower price than I had bought it in the past.

was having problems with my mouse constantly double clicking used this on it and cleared it up good its like a brand new mouse :) though watch out if you have any special color paint on your mouse it removes it i decided to put some of the liquid on a cotton ball and clean my mouse of debris and any stickiness from any food spillage and it removed some of the silver pain on one of the clickers i had not a big deal as it was only a small button but might be a big deal for those fancy decorated mice. thats if your using it for such a thing.
