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 ## Frequently Bought Together - WD-40 Specialist Penetrant with Smart Straw, Twin-Pack 11 OZ - WD-40 Specialist Silicone Lubricant with SMART STRAW SPRAYS 2 WAYS, 11 OZ - WD-40 Specialist Contact Cleaner Spray, 11 oz. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ie/products/446590234-penetrant-with-smart-straw-twin-pack-11-oz](https://www.desertcart.ie/products/446590234-penetrant-with-smart-straw-twin-pack-11-oz) --- *Product available on Desertcart Ireland* *Store origin: IE* *Last updated: 2026-07-05*
