Great for long term firearm storage

I was using 0w20 Full Synthetic Motor Oil but I tried this in a high humidity area and it works great. I now spray all of the tools, saw blades etc in the shed when storing. Works fantastic.


No dust

Been using this on my equipment for about 12 months, no dust build up. As I live on a dirt road that's important, all other type of lube seem to attract and capture the dust.


Who Would Have Thought

I actually use this product in radio repair.


fantastic cleaner

I am restoring my Honda pilot fl400r after it was sitting in storage for 17 years and had accumulated a nasty layer of grime and dried in oil. sprayed the engine with this and I only had to use a toothbrush for a few nooks and crannies to make it like new. the engine has come up like it was only stored yesterday.


Not dry but oily

I was hoping for just a dry teflon powder deposit but instead it was a clear oily substance wthout any visible teflon powder, and it didnt have the water repelling properties of teflon either.

Amazingly great and no smell like others

I recently bought an older car and it had years of oil spills, dirt and grime. I looked on line and found a few products that are petroleum based, smells bad and damages hoses. I trust WD-40 lubricant so I thought I would try the Engine Degreaser. AMAZING results in 5minutes!! You could eat off this engine now! If you wish. Thanks WD-40



I bought this because I restore vintage electronic components, so when I saw the reviews I was happy that WD40 had a Electrical Contact Cleaner as a solution. First can I bought I read the instructions and made sure to shake well. The can was full but I got 90% air blasts and the cleaner itself would come out in drips.... I figured bad batch, second can I bought same exact thing. Seems like I can use it more as a compressed air can.

Very good dry lube

I have been using this for about two years on numerous applications. Works great as a thread lubricant for wood screws. Works on electronic device buttons and mouse rollers. Use it as a mold release, on cable drives for flexible shaft tools, locks, doors, hinges or any place where an oily film is undesirable. The product dries quick in seconds and leaves no visible residue but the lubrication it provides is superior at least an equal for silicone and light machine oil. It seems to stick well to surfaces and using it on wood screws as a lubricant to ease driving force works very well. It also has high temperature resistance up to the point where PFTE fails above 500F. That is impressive. In conclusion, this is the best dry lube for general use I have found. Will definitely use it as my go to dry lubricant spray. It is simply superior.

Did not do cleaning good

I sprayed this foam to clean the oil pan on my car because pan was leaking oil for sometime. It did the same thing as if I sprayed water, so no cleaning at all!
