K&W Technician Grade Knock'er Loose Lubricant Penetrant 401712 – 9 WT. Oz. Rust Penetrant for Corrosion Free Applications

The best rust solvent I've seen in a long time. Sprayed the impossible nuts and left them overnight. The next day, the nuts spun off with minimal resistance. Very impressive

I don't have the words to express how impressed I am with this stuff. Example: I have a flagpole suitable for a 3x5 flag mounted to the rail on my deck. It's one of those fancy flagpoles with ball bearings down at the base of it so that the pole itself will rotate with the flag as it flaps in the breeze. The result is that the flag should never get tangled up or wrap itself around the pole.Using other lubricants (Ballistol, 3-in 1 Oil, Silicon Spray, white lithium grease), if I didn't lubricate the base a couple of times a week, the flag would start getting tangled. I applied Knock'er Loose ONCE on November 8, 2023 and it's still flying freely. That's 46 days without having to apply a second dose!Needless to say, as a penetrant, it can pop the most reluctant of frozen nuts and bolts loose, and it doesn't have to soak overnight to do it. I typically will spray the frozen offender, wait a couple of minutes, and then pop it loose. My neighbor comes over here with his frozen stuff for me to break it loose for him!I know CRC owns K&W and makes a product with the same name but in a different spray can. This, the <bold>K&W Technician Grade version in the shop sized can</bold> is the better deal at 18 oz for $9.79, compared to 13 oz of the CRC Industrial Grade version for $11.35. This is great stuff!

This is the BEST PRODUCT ON THE MARKET!even though PBlaster is good This is 1000% Better than PBlaster even though it is made from the same company. Once you use Knocker Loose you will never use any other penetrant.Knocker Loose dissolves Rust instantly

Some of the best if not the best penetrating fluid. It breaks everything loose I use it on

Did what it was supposed to do

Works very well

“Technician Grade??” It appears to just be the same thing as the original red can CRC penetrant. I was looking for the same thing (or better) as the orange ‘KNOCK-ER-LOOSE’ in the copper color can. Apparently ‘Technician Grade’ just means bigger can.

Yes it is, The best parts loosener in my 60 years in the industry. Plus it has a bit more volume than the store volume. Give it a try, a goid value also.
