Arctic Hayes Crack-It Shock Freeze Release Spray, Bio-Degradable, Fast-Action Lubricant, Breaks Apart Corroded Parts in Minutes (400ml)

I bought this to help while working on an older car and trying to undo rusted bolts and nuts. This was a great tool and combined with a blow torch to heat the nuts then a blast of this spray to cool it to break the rust and lubricate this. It worked very well and certainly worked for me. It is better value here than other stores. Will buy again.

Great item, great cost, quick delivery !!!!

Zero points really , doesn't work, sprayed it on a steel bolt stuck in an alu head...1 minute maybe, with application in stages, barely frozen, I used an air duster, did 10 times colder, but no bueno, ended up welding a nut, free in 30 seconds, save your money... no penetrative agents in it either from what I could tell !!! Junk.

I bought this to freeze a stuck bolt in a classic car. It does cool down the metal, i didnt think it was anywhere near -50c and i used the whole can on one bolt in three attempts to release the bolt but it was no avail. The spray didnt seem to make any difference at all. I doubt I’ll use this again.

Had tried several ways to undo a large flywheel nut on a 14HP Briggs & Stratton mower engine. Would not budge. Then applied Crackit per instructions. Then reapplied socket with long extension and hit it with hammer as before but this time it suddenly gave way after which the nut came off easily . This is not the first time I have used this product. I have also used it successfullt in the past to remove a recalcitrant gear box pulley.

Works only as a release spray, no better or worse than plus gas.

As some may know, Campagnolo Power Torque carbon cranksets are notoriously impossible to remove using the designed-for-purpose tool. Filling the hollow crank with cotton wool and freezing it with the spray meant knocking the chain set out from the non-drive side was surprisingly easy. This stuff works.

I may have received a dodgy batch, or possibly a previously returned item (there was no nozzle attachment as per the photo), but all it did was spray slightly-less-than-room-temperature lubricant. It certainly did not do what it says in the tin. Very disappointing.
