Silly Straw Design

What a problem this new design is... this is a corrosive product and it oozes from the side of the nozzle, instead of going through the tube dispenser... this silly customer representative keeps telling users to go watch a video to figure out how to use it... to use what should be a a simple aerosol can , I now have to watch a video to figure it out... I am on amazon looking for a better alternative

Doesn't live up to rust claims

"Disolves and protects against rust" (paraphrasing), they say. No it doesn't, in my experience. I needed a good rust remover/protector for my evaporative cooler but it only worked marginally. WD-40's Forte is as a penetrant; at that, it'sspectacular.

Thanks for writing to us, and for sharing your feedback about this product. We're happy to be able to provide you with an immediate solution through the recommendation of our WD-40 Specialist® Penetrant formula. It's specifically designed for the uses you describe, and should serve you well. Thank you for choosing WD-40® Brand Products. https://www.wd40.com/products/penetrating-oil/

Great product, horrible packaging.

I have used WD-40 for decades and would not pick any other product over it, however the new flip up straw is horrible. It leaks all over every time I use it. Please go back to the detachable straw, It must be cheaper to produce, and it is way more effective.

Thank you for sharing your feedback about both the product and its packaging. We appreciate your insights and contributions to making our products better than they are today.

Discontinue this faulty design

Love the product but the ridiculous spray design does not work. I have 5 cans at work with half left and will not spray and a NEARLY FULL CAN that WONT WORK. I am furious, this stuff is not cheap to throw away.

Hi, thanks for sharing your feedback. There are a couple possible causes to investigate when the can doesn't seem to spray properly. Check out this video and the 2nd question on or FAQ page for some more details as to what might be going on: https://www.youtube.com/watch?v=Opl6mp91Pto https://www.wd40.com/how-to/faqs/ If the issue persists, we're happy to help address a specific concern with you and work towards a resolution. You can contact us on the number on the can or via our webpage (https://www.wd40.com/contact-us). Thanks for taking the time to write to us and for choosing WD-40® Brand Products.

Does not work

I had purchased two of the wd40 cans one with silicone and the other for rust. Neither of the two cans worked almost from the beginning. The ones I had have a yellow cap and it essentially did not stay in place when using the cans. Essentially sprayed or leaked out the cap.

I like the wd-40 BUT

The smart straw cans let me down in 2 ways: (1) they keep spraying for a full second or two after you release the nozzle, and (2) I can never get the full amount of product out of the can! Idk if there is not enough propellant or they leak, but good idea, poor execution.

Great idea for 1/4 can

It is a great idea but needs a lot more engineering to make the nozzle last and then to make the propellant last past 1/2 of the can. I contacted them multiple times---crickets!

Worthless Product

Awful awful design. Smart straw is completely useless, bought three 8oz cans and all of them sputter and leak but don’t spray. It’s a useless creation that undermines the brand value of WD-40 and a disgrace. Avoid like the plague.

Horrible Smart Straw - AVOID

If you plan to only use the WD-40 1-2 times them the smart straw is fine, anymore then that and the plastic top will break leaving you unable to dispense the WD40. Have several 90% full cans that just need a working top... have contacted WD-40 and been total ignored.
