WD-40 Specialist® Penetrant with Flexible Straw

WD-40 Specialist® Penetrant is a fast-acting penetrant with capillary action to penetrate deep into crevices, threads and seams to break the rust bonds that hold stuck parts together. It is a low odor formula that works on contact to free rusted nuts, bolts, threads, locks, and chains leaving behind a protective layer that prevents rust and corrosion from re-forming. Now the job is even easier with our proprietary 8” flexible straw that bends and keeps its shape, allowing unlimited access to hard-to-reach places.

  • Penetrates rust to free up stuck, frozen, or seized equipment and parts
  • Safe to use on metal, rubber and plastic parts
  • Ideal for use on nuts, bolts, threads and locks
  • 50-state VOC compliant

Spray Does not Work

I purchased WD-40 Specialist Penetrant with Flexible Straw, 13.5 oz. When I try to use it, the liquid leaks from around the cap rather than flow through the straw. Seems like there is a defect in the cap attached to the straw and does not seem to fit on the can properly. It leaks all over and wets my hands rather than spray on the object. I also contacted customer support but there has been no resolution

Flexible Straw is the best

WD-40 has always been a brand and product you can trust and rely on. Now they have made things even easier with a flexible straw. Makes getting into hard to reach areas so easy. The formula is fast acting and just gets the job done.

Much appreciation for your thoughts and insights. We value your feedback, both with success stories and with ideas on improvement. Very glad to hear this product is serving you well.

Awesome!

Used it to loosen my caliper mounting bolts. Could not get them loose with my impact gun so as a last resort I sprayed them with the penetrating lube let sit very short while hit them with the impact gun an bang loose they came! Thanks. The only bad news is now I have to buy more

Works great, love the flexible straw

I used the WD-40 Specialist Penetrant Fast Acting Formula with Flexible Straw on several of my door hinges, including the ones on my shed outside. I love the flexible straw. It really came in handy with those hard to reach angles. I do feel like the Wd-40 brad did well with this product and it really fits in with their brand.

Multiple Spray Functions Allow This WD-40 to Reach

Wherever you're trying to reach, this WD-40 Specialist Penetrant will probably do the job! Aside from being about twice the size of the original WD-40, this product offers both a spray function and a stream function that can be angled into any crevice with the flexible metal straw. The straw can be bent in multiple ways to reach a rusty nut or other hard-to-reach machinery parts. And it still works like a charm to cure the typical squeaky hinges and stuck parts.

Works Great

This product is the same trusted WD-40 that we all love. It just works faster and has a flexible straw. The flexible straw is awesome. It allows me to reach every area that I want to while spraying. It works fast and efficiently.

Amazing product!

I purchased tires and rims for my vehicle and had tremendous trouble taking the bolts out with the tools I had. I decided to try this product, and only used a few sprays but was pleasantly surprised at how good this product worked. I let it sit for about 2 to 3 minutes and went back to try to loosen the bolts on the tires. The screws came out with such ease and I’m so grateful this product assisted me to achieve the goal I needed. The product came quickly and packaging was very nice and neat. When I’ve tried other products of this nature, I noticed it would leak around the spouting area and it would cause the product to run down the can. With the placement of the hose, I noticed I save so much more product to use for the next time and also I haven’t noted any leakage since I used the product. I would highly recommend this product to family and friends.

Works like a charm!

Perfect no mess

WD-40 Specialist Penetrant Fast Acting Formula with Flexible Straw is perfect to free those old and rusty joints. It doesnt make mess as it has flexible straw. Its smell is not very powerful i mean one can be ok around it.

Excellent

The adjustable tube is the best addition to this product. Finally, we can adjust the tube to pinpoint where we need the product to be sprayed. Direct the spray and let the magic begin! I have a new love of WD-40!!
