I HAVE TWO SMART STRAW CANS THAT DON'T WORK

I bought these cans several months ago as I leave one to lubricate my lawn mower when I put it away and the other I have in my laundry for general use. Both cans have stopped working, one can is almost full and the other is maybe half full. When I push the top whether with the straw up or down nothing comes out

Trouble with spray nosels

I have recently purchased two 12 oz. Cans of WD-40 WITH THE SMART SPRAY! Both cans quite working to spray with 1/2 of the cans still full. I feel like I am due some compensation for these faulty cans! I will not purchase these type of cans again.

Smart Straw doesn't work - makes a mess!

This nozzle is poorly designed. When I rotated the nozzle-straw assembly up to use it, the product simply leaked out all over the place at out of the button and made a big mess. Cheap design.

The nozzle is useless

In a review that I have written for another WD product I expressed how much that I liked WD-40, but this I just cannot abide. I have several cans of WD-40 that have the Smart Straw nozzle which I have had to purchase because, for whatever reason, my retailer of choice no longer sells WD-40 in the old style can. With all of them the nozzle has stopped working after having only used about 1/4 of the can. I have used and trusted WD-40 for many years so, as you could imagine, I am very disappointed in this product

Malfunctioning Nozzle

The solution comes out from holes on the part of the nozzle that I don't know what is for, and not on the intended nozzle/straw. I bought a large can and now I can't return it. WHAT A WASTE! I just hope you make up something for it.

Fast reaction.

I purchased WD-40 smart straw a couple of weeks ago and I'm so glad I did. Every year my doorknob gets stuck. Especially around the winter months. I applied the product on my door knob. The smart straw allowed me to spray the product at a distance. The spray didn't get on my hands or clothes. I let the product sit for about an hour. Then i was able to unlock my door. I really like the fast reaction of this product, but the odor is too overwhelming.

Thank you for your review & feedback! We're glad our product helped fix your door. As to the scent, some people seem to love it but it's not for everyone! You can try using it outdoors or in ventilated rooms when possible, or even spray on a rag outside then use indoors. Might not work in all cases, like with your door knob, but WD-40 products are built for creative uses!

nozzle quit working

I now have two cans that will not work! and receipts for stuff like wd40 isn't something i keep. That "Smart Straw" is junk

Hi Jackie, Thank you for taking the time to contact us. We know it is frustrating, but sometimes customers have trouble using aerosol cans and getting all of the product to come out effectively. There are a couple causes to investigate. First, the spraying position.. We recommend you spray fully upright or fully inverted. When tilted, the propellant may be released without the product and eventually all may escape before you run out of the can’s liquid contents. Also, shaking the can before use helps a lot - WD-40 Multi-Use product is both a mixture and a solution, so it needs a good shake for optimal performance. Check out this video and the 2nd question on or FAQ page for more information: https://www.youtube.com/watch?v=Opl6mp91Pto https://www.wd40.com/how-to/faqs/ If you think the can was faulty then see this page for next steps: https://www.wd40.com/contact-us/ Hope this helps! Thanks for choosing WD-40 Brand products.

Terrible

I've almost given up on WD40. Have gone through 3 cans that have stopped spraying almost right away. What a waste of money. Please fix this or start selling the old cans with separate straw as an alternative. The old cans worked.

Hi, Thanks for your review, we appreciate your concerns. Do you think your trouble came from the straw, a problem with the can, or some other factor? Shaking the can before use helps a lot - WD-40 Multi-Use product is both a mixture and a solution, so it needs a good shake for optimal performance. Check out this video and our FAQ page for more information: https://www.youtube.com/watch?v=Opl6mp91Pto https://www.wd40.com/how-to/faqs/ If you think the can was faulty then see this page for next steps: https://www.wd40.com/contact-us/ Hope this helps!

Same Problem As Others

Wasted about 1/4 of can because it would not spray anymore...I did see some videos online that you can go get a some type of tire thing and refill with air compressor...Too much hassle for me....
