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 ## Customer Reviews ### ⭐⭐⭐⭐⭐ Amazing product！ *by J***G on May 8, 2026* Amazing product！Excellent rust remover and lubricant.
