The most powerful penetrating lubricant

The most powerful penetrating lubricant

The penetrating lubricant that will be discussed is many times superior to the most common WD-40, which everyone loves to use when unscrewing old, rusty bolts and nuts.
Very often, when trying to unscrew a rusted threaded connection, we fail and the bolt breaks. This is not so scary if there is free access to it and it is easy to replace. But our life is not without irony, and by bad luck, breakdown occurs in the most inaccessible place. Or a place where the pin breaks at the root and there is no other way out other than drilling a hole.
To avoid such cases, or to extremely minimize this result, our own lubricant was developed.
Everything was learned through experience.

The first recipe for a powerful penetrating lubricant


This option is great for heavily rusted parts.
The composition is as follows:
  • White spirit - 50 gr.
  • Dry lubricant, Forum type - 5 g. Another one is also suitable - graphite, molybdenum, etc.
  • Rust converter, such as Zincar, Zinkor, etc. - 50 gr.

Making penetrating lubricant


Pour white spirit into the container.

Then add dry lubricant.

And a rust converter.

Mix everything well and pour into a spray bottle.

We test it on a friction machine.

The result is that the machine shaft could not be braked when the load on the lever was higher than 11 kg! Although the purchased WD-40 made the shaft stop already with 4 kg of applied force.
Now let's test a homemade penetrating lubricant in real conditions. Let's clamp the rusty stud and bolt in a vice. Spray with lubricant. A reaction will be immediately visible, since the composition contains a rust converter that will react to corrosion.

And as a result, the nut unscrews very easily.
The secret of such a lubricant is simple: Rust converter eats away rust, white spirit promotes good penetration, and solid lubricant has a good lubricating effect. As a result, our goal is achieved - the nut is unscrewed, the stud is intact.
But this miracle lubricant also has its drawbacks: it must be shaken each time before use. Dry lubricant particles can also become clogged in the spray nozzle.
Well, it is advisable to make such a composition in small quantities and only before use, since the properties, in my opinion, are significantly lost after prolonged storage.

The second DIY recipe for a powerful penetrating lubricant


The second composition is more stable and is designed to radically reduce friction in threaded units when unscrewing them.
Compound:
  • Solvent white spirit, 646 - 50 gr.
  • Waterproof lubricant, graphite, Zelenka type - 5 g.
  • Anti-friction additive Prolong - 10 g.

Add lubricant to the mixing vessel.

Then pour in the solvent.

Stir until the lubricant is completely dissolved in the solvent.

Add an additive.

Again, mix everything well and pour into a spray bottle.

Comparative test in real conditions with WD-40


Let's clamp the rusty bracket with nuts in a vice. First, spray with WD-40. Let's turn it around so that the lubricant gets into the threads. Next, take a torque wrench and measure the force.

The initial force without lubrication is 56 N/m. With WD-40 the force was just over 42 N/m. The lubricant from its own composition showed a force of much less than 42 N/m. But it was not possible to measure below, since the key does not allow it - the scale has run out. But it feels like the force applied to unscrew it is significantly lower.
As you can see, such homemade lubricants work great and are easily superior to available commercial counterparts. So friends, make your composition and you will forget about broken bolts and keys!

      Before tightening the nuts on the manifold, rub the threads with graphite powder. I repeat, powder not lubricant.

    When assembling, I lubricated the threads with Movil. After a few years, everything came off easily.

    I have no doubt about the ability of such a product to work, but still;
    "The initial force without lubrication was 56 N/m. With WD-40 the force was just over 42 N/m. The grease from its own composition showed a force much less than 42 N/m."
    It doesn't seem entirely correct to me. After all, initially it was already lubricated with water..

    WD40 is not a lubricant but a solvent for old dried grease

    Dear friend. You understand the phrase penetrating lubricant. And where will your spirit penetrate? no need to compare with the Vedashka.

    Vd-shka is not a lubricant, as we have already written above, it is a mixture of mineral oil with a solvent, and comparing it with a mixture of molybdenum is stupid, it’s like comparing Vd-40 with a mixture of autol and the turbid solvent...

    I always use 80% vinegar. It costs pennies, doesn’t require any chemicals, and works great. 15-20 minutes and any nut is unscrewed.
