WD-40 Specialist Penetrant & 3-in-ONE Garage Door Lube Combo Pack, Penetrant for Breaking Rust Bonds & Lubricant for Smooth Garage Door Operation, High-Performance No-Mess Formulas, 11 Oz.

This is the greatest stuff!!!!!! I am a 75 year old grandma that had major back surgery 6 months ago and home repairs had been piling up. This "specialist" wd-40 loosens rusty nuts and bolt like magic! Yesterday I fixed my 12 year old lawnmower and now I am changing out a bathroom faucet that was installed in 2007 My son in law couldn't even loosen some of the water hoses, today I squirted them with this Specialist WD-40 and I got them all disconnected. Only problem is that the spray button is very hard to push, it takes both hands to press it down! I am buying more cans of this (so I can spray the top of the can) Very low odor!!! The can empties pretty fast! I cannot believe it is cheaper than regular wd-40. I am ordering two more cans this time.

Works well! I used for my office chair to make the wheels easier to roll, so the straw makes it so easy to apply/use. Great value for the money. Recommend!

WD-40 Specialist Penetrant did exactly what it’s supposed to do — it penetrated stuck bolts like a champ and lubricated as it went. Broke loose some stubborn parts with ease. Definitely keeping a can of this in the toolbox at all times.

Worked wonders on our sliding glass door track! No more pulling a muscle trying to open/ shut the sliders. Great little straw house for exact application. Also great on squeaky door hinges!

The product itself is established, dependable, and is always a great go to for those little jobs that need lubricating, loosening, or whatever. So five stars for the product.The new spray can, on the other hand, is a huge PITA. If you don't hit the sweet spot just right, you may not get any product at all. When it does work, it works well but you can't always hit it just right. In other words, the spray mechanism is more difficult than it needs to be. I did not mind the days when I had to poke the straw in myself because then it always worked. So about 3.5 stars for the nozzle itself.

Arrived on time and the cost was more than fair! How did it work? What I would expect WD-40 to do. Terrific product as always. And that straw makes it very convenient. Terrific as always!

WD-40 is an excellent product for removing squeaks.

Cheap, works well, way less messy than PB Blaster, and smells like regular WD-40 (for those who like that sort of thing).Way easier than coming up with ridiculous hacks to create your own penetrant, and the dual spray function does come in handy often.
