PB Blaster Penetrating Catalyst

Any of us that live in the rust belt and have worked on a Jeep that's been around a few years knows the aggravation of trying to get loose a nut or bolt that has rust fused itself.  In our experience the best penetrating fluid is PB Blaster.

This spray has been the most effective product we have used.  Here is some tips on removing those stubborn bolts.

  • Excessive muscle will just break off a bolt and make things worse.

  • Apply plentiful amounts of PB, give it some time to soak in.

  • Gently rock the nut or bolt, this can help break the bond.

  • A torch will be useful if the PB alone will not work.  BE CAREFUL!  The PB may burn and so may many other things surrounding the nut/bolt.  When using a torch try to heat either the nut or the bolt but not both.  After heating immediately try to loosen it.
