Does Water work better than Penetrating Oil for Rusty Bolts? Let's find out!

  • Published: 29 April 2019
  • Does water work better than penetrating oil for removing rusty nuts and bolts? Also, can water or penetrating oil climb a vertical surface and creep into a rusty nut or bolt? I've had quite a few viewers recommend water over using penetrating oil for removing frozen nuts and bolts. What about diesel? In this video, water, diesel, 3-in-1 oil, Gibbs, Free All, and Mouse Milk compete to see which product is best using 3 separate tests. The Project Farm channel is not sponsored by any of the manufacturers of the products tested. I purchased all of the products tested in this video. Hope you enjoy the video and hope you provide comments on future video ideas! Thanks for all who recommended this test. 100% of the videos on this channel are viewer recommended ideas.

    I would have liked to see chain saw gas as a penetrating oil,I use that for freeing up old engines.

      @Project Farm have you done a test on grease to find out what type or brand is the best? Grease gun grease I mean

    Try SOK penetrating oil. It’s hard to find on shelves at stores but can be ordered. It works like magic

      Great video. We have always soaked our chains from tow to chain saw in diesel. We run a lot of saw chains for trimming trees. Just pull them out of the diesel bucket, use them, throw in dry bucket, sharpen, throw in diesel again. Also dump old diesel in barrels for posts and other fence material. Diesel works great on 3 pt hitch adjusters, 5th wheel slides, or any other in the weather item that seizes up. You have great real world videos. We dont need expensive "penetrants/lubes" but they do work well. I remember a buddy in high school who lived in town and had no idea about really working on anything. He brought his mustang out to the shop (yes we had real V8 mustangs) to put new shocks on it. He could not get the rubber bushings on the shocks and I said SPIT ON IT. To this day 35yrs later he still laughs and says "spit on it" when we get together.

                  Very nicely done video.

                  SUMMARY: ALL of the penetrating oils are approximately useless. Based on the variance in the torque to loosen the nuts, I doubt any are reliably better than the control. And THAT seems to coincide with my experience with these products.

                    All in all it seems that there is not much difference in removing the nuts; it seems that they pretty much came lose with the same amount the got torqued.
                    To me that means that the rust did not creep deep enough into the threads yet. Besides that, keep up the good work, I love your tests.

                        I don't think water had fair shot. The people using water are not letting it soak. They're most like using it on a bolt or nut they taking off immediately.

                            I know it's not supposed to be used as that, but for years I've used WD-40 as penetrating agent to loosen rusty bolts and nuts with moderately good success. I would have liked to see it compared to specialized penetrating oil products.

                            How does heat affect these products? I often use a torch to free larger nuts in severe conditions such as farm equipment.

                            Have you considered applying heat in conjunction with the penetrating oils? It would be interesting to see how the different products react.

                                The best stuff is a 50/50 mix. Auto trans fluid and acetone.
                                Works better than everything.

                                It has been tested that hydraulic fluid works really well but since it is made out of 95% vegetable oil, that makes me wonder a bit whether it would be a cheaper but similarly effective rust penetrant?

                                  Good stuff. I now check in with your videos before buying products. I especially admire your effort to maintain rigor and showing your work puts you a step above Consumer Reports. As I've mentioned before, in some instances (such as this one) the data are inconclusive because of small sample size and broad variation which make it difficult to say if the difference between the means is statistically significant. I've mentioned that the T test was designed for these situations. Your reply suggested you weren't comfortable with the required analysis. The Excell spreadsheet has several T functions built in to its statistical function library. Also, an explanation of T testing can be found here:

                                  I mix my own penetrating fluid, sounds crazy, but it works really well for me, it would be great if you could test my mixture, 50/50 Seafoam Hydra Trans Tune and Acetone nail polish (I would rather use a stronger concentration of acetone if I had it available.) Maybe for the video you could try different mixing rations and a homemade mixture ChrisFixs video Homemade Penetrating Fluid claims is better than any product available, a 50/50 mix of Valvoline Max Life Synthetic ATF Dex/Merc and premium acetone. You could try different ratios to make a complete video/test?

                                  i think the biggest issue is that the torque is too low, to really show what the different oils can do, at ~130 ft/lb's no one is going to use a penetrant anyway on a bolt like that, you should use some 3/4 nuts and torque them to 300+ ft/lbs then see what they can do.
