CRC Freeze-Off Super Penetrant, 11.5 oz

Works great for heavy outer rust and penetration. Not as much waiting (or waiting forever, for other products to do nothing.) Definitely a specialty product. Plenty of stuff can do the same, but this can do it faster and just as well...usually better.

Saved me on frozen door jam works great

I could not get the under car aluminum cover off to change the oil in our 2023 Civic. The rear two screws were frozen. I followed the directions on the can and sprayed each for 10 seconds. I added a few taps on each screw head with a small hammer (not in the directions) After 5 minutes I used a JIS Phillips screw driver and they backed out with a firm turn on the screw driver. This would not have happened without the Freeze Off. I had previously tried with two different penetrating sprays.

I was a little skeptical on buying this, but had some pretty tough bolts on a brake job. This stuff worked as advertised and didn’t have to worry about heat.

This stuff works great! Got me out of a jamb Not only did it release the screw it lubricates things nicely.

I was trying to remove the lower and upper pins and bolt from the hydraulic tilt unit on a 1994 outboard. The outboard of course is aluminum and the pin and bolt is stainless,they were seized and wouldn't move. I tried heat along with hammer and brass bar with no luck,at the same time I was applying four different penetrating oil and SUPER Duper penetrating oils,I would walk off and leave for days,no luck. I went online looking for ways another suggestion or advise from anyone and found an article that suggested using CRC FREEZE OFF PENETRATING OIL so I ordered two cans followed the instructions on the can and IT WORKED,I tried the lower pin first because it was the easiest to get to,I sprayed the two aluminum parts on each end that the stainless 11" rod passed through and left it for 15 minutes or so,came back and struck the bolt with the same technique as before and it moved,it eventually came out and I was very happy. The top pin was more aggravating because of its location but by using CRC FREEZE OFF and a tool designed for removing the 5" X 5/8 pin along with a little tapping from the opposite end,I prevailed. I will say that without finding out about and using CRC FREEZE OFF I really don't know what I would have done because I tried every other way that I had used in the past,couldn't have done it without FREEZE OFF without damaging the aluminum parts.It was also priced less than some of the other penetrating oils that I used, it was the FREEZE OFF allowing the metal to contract and letting the oil seep in to work. I do not work for CRC but I have suggested to several auto parts stores to stock it and have told numerous other shade tree or home mechanics about the product.

Worthless! I sprayed it on things that I need to loosen up with a little rust on them. It did nothing..

Worked great for I tried it on. Didn't have to break out the smoke wrench. One time paid for the can.

As described

Expensive but works really well. Very efficient at cleaning rust and getting lubricant in hard to reach places

Works awesome I was extremely shocked when it took off a seized nut that my impact couldn’t budge.

I had some "frozen" bolts on my old lawnmower that no wrench in my shop could loosen. I did a once around on all the bolts and let it soak in for a half-hour or so and - PERFECT! They all came off so I could do my repairs. This Freeze-Off would probably work well for tough to remove screws or bolts on car repair. Good stuff!

absolutely great stuff / a must have / unfortunate that it is so expensive in Canada
