CorrosionX Corrosion Technologies 91002 (16 fl oz trigger spray) – Multi-Purpose Lubricant, Penetrant, Rust and Corrosion Preventative | Industrial Strength | Marine Grade | Cleans Lubricates Protects

Used this for years mostly on boats. It works good.

I spray this on many things that need protection from rust and corrosion, and it's just that easy. It's an easy choice for annual maintenance. I wish stores carried this, but at least the bottle will last a long time. If I had a new car, I'd easily go through a bottle just spraying everything under it as well as motor parts like injector tops, basically anything that might need replacing over time. It'll help make the removal of those things easier.

A professional plumber turned me onto CorrosionX many years ago and it's my go-to for rust protection and lubrication on my bike chain, for old pipes, for crusty old nuts and bolts that won't turn and anything else made of metal that needs a good scrub. It's worth every penny because it works fast and it lasts.

Been using this product since boss got it to try out. Retired from HVACR 12 years ago and have kept a supply of Corrision X on hand ever since! Works on EVERYTHING! PROTECTS AGAINST MOISTURE! If something starts to make an odd noise a single spray and its like new!! Wouldn't be without and when wife saw the good job it did she used all I had on hand so had to buy more. Had to convince her a single shot was enough. Thanks for this product!! Over last 50 years tried them all and this is the best!!!

Very expensive. Claims to stop rust in its tracks. The product goes a long way though,And should last me for many years.All you need is a tiny bit to cover your tools, bolts or Whatever you're working on.The sprayer absolutely sucks.I think the liquid is too thick and when you Use the spray pattern that always comes out as a stream.

No better lubricant and corrosion protector out there. Living in Florida this works great in the marine environment.

Excellent product.

You have the choice to buy this is an aerosol can or this pump bottle. Even with the tube, I was afraid I could get it where I wanted it in small RC electronics. So when I got the pump bottle, I was really happy that I had the choice of how to apply. First I could mist spray or stream spray. Misting is almost like aerosol, except you get a lot more product in the pump bottle for the money. Second, the stream spray allowed pretty good placement in small electronics. A small art paintbrush was perfect for spreading CorrosionX around on a circuit board, etc. And finally, if you want to dunk, it is easy to fill a small dish with a few pumps of the spray bottle. So, my review is about how to apply more than the effectiveness. I can say that this dielectric fluid is the best. Absolutely no hindrance of electrics passing through it even on the smallest connections. I use on RC boats, and it is really bullet proof.
