I needed to replace some exhaust parts on a nearly 20 year old car and the studs were completely rusted and looked like they would need to be cut out. I sprayed this on all of them and let it sit for a couple of hours before trying to remove them, fully expecting to break at least one of the studs off due to corrosion. Instead, when I came back a lot of the crusty looking rust was gone and after working the nuts back and forth I got all of them off without issue and was able to reuse them. It's an expensive spray but that bottle is a decent size and it sprays on easily. Whatever is in it works extremely effectively at lubricating through the rust and letting you get heavily rusted nuts off. Long story short, I highly recommend this stuff. ## Features - Causes serious eye irritation. - Causes skin irritation. - Contains gas under pressure; may explode if heated. - Extremely flammable aerosol. - May be fatal if swallowed and enters airways. - May cause an allergic skin reaction. - Toxic to aquatic life with long lasting effects. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0013IZS1O | | Item model number | 03027 | | Product Dimensions | 27.94 x 20.32 x 25.4 cm; 376.48 g | ## Product Details - **Brand:** CRC - **Flash point:** 64 Degrees Celsius - **Item weight:** 376 g - **Liquid volume:** 11.5 Fluid Ounces - **Package information:** Tin ## Images ![CRC 03027 Knock'Er Loose Plus Penetrating Solvent, (Net Weight:11.5 oz.) 20oz Aerosol by CRC - Image 1](https://m.media-amazon.com/images/I/71KcEWHWojL.jpg) ![CRC 03027 Knock'Er Loose Plus Penetrating Solvent, (Net Weight:11.5 oz.) 20oz Aerosol by CRC - Image 2](https://m.media-amazon.com/images/I/81tynFGfHzL.jpg) ![CRC 03027 Knock'Er Loose Plus Penetrating Solvent, (Net Weight:11.5 oz.) 20oz Aerosol by CRC - Image 3](https://m.media-amazon.com/images/I/71oR-QDrYeL.jpg) ![CRC 03027 Knock'Er Loose Plus Penetrating Solvent, (Net Weight:11.5 oz.) 20oz Aerosol by CRC - Image 4](https://m.media-amazon.com/images/I/81qFKaiHBIL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by Y***. on 16 September 2025* Works better than any rust penetrating fluids out there never had a product work as good and as fast as this one ### ⭐⭐⭐⭐⭐ Review *by A***A on 15 October 2025* For $15 I was blown away at how well this stuff works.
