## Questions & Answers

**Q: Is this formula very different from original wd 40 (which didn't work on my rusted outdoor light fixture screws)?**
A: This version is better at loosening rusted parts.  But you have  to remember it take time to creep into the threads and work. You can not just spray it on and start unscrewing, I have had severely rusted fittings that I sprayed every day for a week before they busted loose. There is no miracle product that you can spray and go instantly.

**Q: What makes it better than standard wd 40 for rusted bolt and screw removal?  Also does it work better or worse with a torch compared to original wd 40**
A: No idea what makes it better, if you spray a locked up bolt/nut wait 5-10 min then remove it. 
I’ve had very good luck with it

**Q: Could this be used to release rust and be followed up an application of WD-40 long term corrosion inhibitor?**
A: This product released rust. but I don't believe WD-40 long term corrosion inhibitor is any better as it only lasts one year outdoor use, I used than 3M or NAPA products those are more permanent inhibitors (more like paint)

**Q: will this remove rust on a table saw table?**
A: Not by itself but if you use steel or brass wool with it, it will help remove rust

### ⭐⭐⭐⭐⭐ Excellent Lubricant for Household Projects

### ⭐⭐⭐⭐⭐ Smart Straw, Smarter Fix
*by E***S on August 19, 2025*

Smart Straw, Smarter Fix I’ve used a lot of penetrating oils over the years, and this WD-40 Specialist Penetrant really stood out as one of the better ones. The “Smart Straw” design makes a surprising difference—you can flip it down for a wide spray or snap it up for a precise stream, which saves both time and waste. I used it on a stubborn garden hose fitting, some squeaky hinges, and even a rusted nut on my lawnmower, and in each case it loosened things up quickly. The formula seems to work fast, cutting through rust and corrosion so you don’t have to force anything and risk breaking parts. Another big plus is its versatility. I felt comfortable using it not just on metal, but also around plastic and rubber parts where I’d normally hesitate with harsher sprays. It dries fairly cleanly and doesn’t leave a sticky residue that attracts dirt, which is often a problem with cheaper sprays. The can size feels generous and should last through many household and garage projects. If I had to nitpick, the smell is strong—like most products in this category—so I recommend using it outdoors or in a ventilated area. But in terms of performance, it does exactly what you want: frees things up without fuss. Bottom line: A reliable, fast-acting penetrant that’s made my life easier on everything from locks to mower parts. The Smart Straw alone makes it worth choosing over generic brands.
