I have a PTO shaft that had sat out in the weather for 10 years, I soaked it every night for a month, smacked it with a hammer and it never moved, I sprayed this on it and after one night It is apart! This stuff is AMAZING!!!

CRC is my primary go-to when it comes to the products I keep around my shop for my DIY projects. So, after I received my Knock'er Loose, I immediately got busy on some rusty mower deck bolts. I was very pleased with the results and only had to heat up one of the dozen or so bolts I had to remove. I feel like it's a very good product that's well worth the money I spent on it. I also appreciate that CRC sponsors several of the Youtube content creators that I typically watch. Honestly, Youtube is how I found out about CRC and their products.

I’m a big fan of Kroil from way back, but I think this product has dethroned that as a penetrant. This stuff really works. That’s all I can say.

Works better, IMO than WD-40 on tough jobs.

This stuff works great! If you can get it on the bolt it works really well fast. 1991 Jeep renegade I got all the bolts out with out breaking any. I spayed them one evening and got several out the next morning. The only ones that didn’t come out were yhe one that are hard to get oil to.The rear corner ones were the worst I had to drill a small hole next to the bushing on both shines and spat the with oil. The following day I got the rest of them out. The only thing I didn’t like was the little straw the supply doesn’t like to stay on the sprayer. Most definitely will buy again

Knocks'er loose all right! Smells great too! Has a strong and concentrated stream so wear eye protection and have lots of cleaner/rags on hand for post job cleanup. Definitely a permanent component of my repair arsenal now.

This stuff is really good, way better than WD40 and even better than PB Blaster!
