I second guessed this at first...lubricate, protect, and clean - noooo; well, yes! I used it to get to the cords behind the washer and dryer and they practically look new (I have no idea what it did to the floor but..nobody walks back there). The precision /extended tip spray wand thingy helps so you don't have to reach that far - even got some on the wall and it didn't stain so that's also a plus.


Nice Features, Works Well

I used this cleaner on an electrical panel unit and was impressed with the cleaning strength and ease of use. The nozzle has two ways of spraying, a larger hole while the “straw” is pointed down, and if a more precise spray is needed, the “straw” can be moved up . It is helpful to have the straw always connected so it doesn’t get lost or broken leaving the bottle unusable. I will continue to use this product.


My go to

I think this product is one of the best brands on the market. It can be used from squeaky doors in houses, cars, to loosening bolts of automobiles. It has a straw to get in the tiniest crevices. Its easy to use that even house wife like me doesnt need to ask the husband for help.


Easy to use

This is by far the best and easiest product to use. It doesnt make a mess and it is very useful when applying to small spaces. I definitely recommend this to anyone who needs this product. I will be purchasing more.


This is great.

I am a handyman and my whole radio system that I use like a DJ stopped working. I decided to fix it my self and use this product. I sprayed all of the push buttons on each of the speakers and then I sprayed the volume and disc control. And It was incredible because immediately I noticed that none of the speakers had the stactic anymore when I used them. I love it. The spray does not harm plastic so it worked out well. Very good product this WD 40 worked extremely well in my application. Its clear luquid form and evaporates quickly. This solves my problem immediately.

Holy what?!

How did I NOT know about this stuff before now? And how did I survive before without it? This stuff is so awesome, it has officially become a staple for my home. I trust this brand 100%. I dont have to worry about any damage being done when the directions are followed correctly


Nice cleaner!

I think this WD-40 Specialist Electrical Contact Cleaner Spray, 11 oz. works really well. It's quick drying. It didn't leave a residue. I like that it's safe on plastic too. One of the first things I used it on, was in between the keys on my keyboard. I really liked it. I would recommend this product.



This stuff is great. I would highly recommend this product to anyone in the electrical industrial because this product does wonders. It doesn’t leave bad streeks or anything this is a 10 out of 10.....

Is it any surprise?

WD-40 has always been my go to for any project. This product is def no exception. I am never disappointed with this brand. This spray helped me clean wires and circuits that i probably would of thrown away any other time!
