WD-40 SpecialistContact Cleaner Spray, 11 oz.

This product works great. Recommended by SportsTutor to clean the switches on a tennis ball machine. Sprayed a few times, cleaned the leads and everything worked. Saved having to replace a on/off switch or the circuit board, which means it saved me time and money. For the price through Amazon and quality of WD-40, you can't beat it.

This product delivered exactly the required performance. The high pressure output effectively cleaned difficult-to-reach areas. The contacts were thoroughly cleaned and restored to optimal condition. I am highly satisfied with the cleaning power of this device. It is a valuable tool for maintaining equipment.

The WD-40 Specialist Contact Cleaner Spray is an essential tool for anyone who works with electronics or electrical systems. I’ve used it to clean a variety of components, including switches, plugs, and circuit boards, and it works fantastically! The spray quickly removes dirt, dust, and oils, leaving behind a clean, residue-free surface that helps maintain the performance of electrical connections.

This works as well as any contact cleaner I've used, of course WD-40 is a respected brand. The can holds a good quantity, and I have used it many times without losing propellant power, and there is still a lot left, so very good value. Recommended.

The best product out there for a long long time. Nothing bits WD40. This product is as good as other WD40 line of products. I used this to clean my car's electric window control circuit which has several tiny electronic contacts. The liquid evaporates almost instantly and won't leave any stain or residue behind. I like this product and have purchased it several times in the past.

Excellent. Easy to apply and works well. Fair price.

Used this on a volume adjustment pot that was making crackly sound when turned...cleared it right up! Highly recommend!!

I had an audio interface for my home recording studio with a scratch volume knob. No reason to replace such an expensive unit when 99% of the time it's just ststic dust build-up on the controller. Very common problem on electrics. Especially older stuff. Pop the volume knob off, spray juat a little of this directly on and around the control shaft. Let it soak in and dry and then hit again moving the volume up and down. This usually works for me first try. Seldomly do I have to disassemble anything and spray directly inside. WD-40 is a trusted brand for all kinds of stuff. I don't mind spending an extra dollar or two considering how much it would cost to replace or repair the electrics.
