Fixed my stereo issues.
I used this on my Yamaha receiver and it brought it back to life like when it was brand new. It hadn't been cleaned out in a few years. It did leave a slight white powdery residue on a board or two, nothing compressed air couldn't remove. The best part is it was a fraction of the cost of the deoxit that I usually use for this type of cleaning. I decided to try it out on an old beater bass guitar I had laying around after the stereo, it did a good job removing the gunk and grime and the scratchy sounds in the amplifier when turning the tone and volume knobs. Just make sure you have a rag handy to quickly remove the grime residue that comes out after you spray an affected area.
I couldn’t have received this at a better time. I have used it to clean just about every unit I have come across since receiving it. It makes my job so much easier since I have to work with electrical components all day long. I highly recommend this to anyone that works with electronics or electrical components.
Works great on battery terminals
Tried this out to clean corrosion on a golf cart battery connection and it worked great. Dissolved the white/blue powder, blew it off, and dried quickly. The new cans with the permanently installed flip up nozzle are excellent! They are far better than the old straws that always seem to disappear. Definitely recommend this to clean electrical connections.
Works great and easy to apply. The nozzle ensures it sprays exactly where you need it. Doesn't have a strong smell. I was able to fix my sons Nintendo switches joycons. It dries quickly without any residue left. Great to have around in case of any electronics needing repaired or cleaned.
We are a service provider for preventative maintenance and repair service for industrial equipment such as compressors, vacuums, and generators. This products works excellent for our service technicians. the directional spout allows you to direct the cleaner inside small orifices and behind components you do not want the cleaner applied to. Cleaner drys fast after being wiped down. Highly recommend this product.
I’ve always been a huge fan and loyal user of WD-40 products. I think they are all great and there is not a product out there that is even comparable. The electric contact cleaner spray is great as well. The flexibility of the tip is excellent and allows you to be very precise in where you want the product to go. Fits very well the the WD-40 name. Excellent product
This works way better than I thought!! I work on cars for a living and using this for cleaning electrical connectors is amazing! I highly recommend this for anyone looking for a good electrical cleaner.
Love this stuff
I ordered this WD-40 Specialist Electrical Contact Cleaner Spray with my computers in mind. I love in a older home where air circulation in not so great. In turn, my computers have a tendency to collect a lot of dust and hair. This stuff powers right through it. It has pinpoint accuracy to get in those hard to reach places. Also is leaves NO residue! Great product and is now my go-to when cleaning my electronics.
I had never used any kind of spray cleaner for my electric products before! I normally just used q tips with a dab of some kind of spray on it and just played with it until it was as clean as I could get it! This took less time and worked a lot better!
Great to have around
Between myself and my family, we have a lot of electrical equipment and electronics. This cleaning spray works awesome for dusting, getting rid of condensation, residue and anything else you find. Having a child around you do end up getting who knows what in small places on electronics, this is great for cleaning that up. Doesn't have a bad smell and is easy to use.
