Worked like magic!

My front door lock was sticking -- so much so that I had to go in and out through my back door. And I'm no handyman. But one spray of this and it was fixed! I just wish I could buy it in a smaller (cheaper) package, because I doubt that I'll need it very often.

Powerful and precise!

Powerful and precise! The dual-pack keeps one by the workbench and one in my husband’s toolbox. The Smart Straw makes it easy to reach tight spots without overspray. Loosens rusted parts quickly and cleans off grime effortlessly. A must-have for any home or garage!

Always keep a can handy

It’s WD-40, what can I say? Every woman should have a can handy like I have for the last 50 years. Yup, even as a tween. Lol…This huge can will likely last me a decade.

Works fine when sprayer keeps working

For most equipment requiring lubrication, WD-40 is fine. Where it isn't the best they tell you about. For example, I need to lubricate my sliding glass door bottom occasionally. WD-40 only works for while - Vaseline works longer, but it's use for something like this is noted. One big beef though is that the spryer mechanism on my my last three cans of Wd-40 failed before the end of the product! Thus the 4-star and not 5. Carefully read it's uses and ensure you are using the right lubrication.

Best WD-40!!! Order more than one can.

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.

Father Approved WD 40!

Father approved . . . My father was born in 1915 and is deceased now but he swore by it. He was a pipefitter foreman at TVA so he should know!
