      Comments about Liquid Wrench Penetrating Oil:

      I used it on the rebuilded of farm equipment and was very good at loosen up very old and rusty bolts. It beats having to cut them off with a torch any day of the week. I have also used it on automotive work and heavy duty truck work and it has not failed in any applications that I have used it on so far. The price is comparable to other blaster products and in some cases you find it cheaper if you catch it on sale. It has been used in some marine applications in our shop has preformed equally as well

            I wanted to replace my broken Craftsman garage door opener, and some of the screws/nuts where stuck and a little rusty. Just gave it a couple of sprays of the liquid wrench, waited for 2 minutes or so then re attempted to undo them. I did however give them a tap with hammer to help loosen them up.

              I bought this because it was on sale, but I'll be buying more! I used it (along with a cable luber) to try to break free my rusted heater cable in my truck. Within 5-7 min, the cable was moving freely like new again. This little bottle saved me big $ on a new cable!

                Comments about Liquid Wrench Penetrating Oil:

                Stays in place and has deep penetrating capabilities. Used in direct comparison with competitor, Right vs Left, in the removal of shackles and struts on truck rear suspension untouched for nineteen years. Liquid Wrench out performed in removal of each bolt &/or nut.

                This is a GREAT product. Just spray it on and give it time to work.

                I highly recommend it to both professional and back-yard mechanics.

                  I used to to loosen the fittings on a rusted on fuel filter. It took a few applications, but it eventually worked.
