Works like it should. CRC is a very good product.

Glad I grabbed the EGO Power+ 4 gallon cordless backpack sprayer for my small design studio’s yard. I already own a couple of EGO batteries for my mower, so skipping the battery and charger made sense. The harness feels decent on my shoulders during a full 4 gallon fill, and the trigger stays comfortable during longer spray sessions. I used it last weekend to treat the gravel path and the edges around my raised beds, and the consistent spray pattern made it easy to get an even coat without drenching everything. The best part for me is not dragging a hose across the patio and around my planters. It keeps the whole space cleaner and I can switch from herbicide to simple water rinse pretty quickly.

This stuff is amazing as long as you can get over the smell.

Aside from Hi$ Kroll, this is probably the best penetrating oil.

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

Been wanting to try this new best product. It was $4-11 cheaper here than any store. Used it on something 5 minutes after arriving, let sit for a minute, and easy peasy. Will save a lot of future headaches, cursing, stripped, and broken bolts for sure!

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.
