Each Mechanism Demands Its Lubricant: Water Doesn't Clear Rust

According to one user, moisture only helps if the blockage is soluble; with rust, it makes things worse. Every mechanism requires its specific lubricant: there is no universal cure.

Each Mechanism Demands Its Lubricant: Water Doesn't Clear Rust
Moisture Won't Undo Rust: Each Mechanism Requires Its Own Lubricant

The moisture is not a universal lubricant. According to Fausto1880, it can only help if what is blocking the mechanism is soluble in water; otherwise, the blockage worsens. This is the short answer to a question that carries an underlying ambiguity: under the word 'lubricant,' one might find motor chain oil and personal care products, and they behave differently and are chosen with different criteria.

Can Moisture Clear a Mechanism?

The answer depends on what is causing the blockage. According to Fausto1880, if the material jamming the part dissolves in water, a humid environment can loosen it; otherwise, water adds to the problem instead of subtracting from it. OjoAvizor maintains that in iron or steel mechanisms clogged with rust, water is useless: iron oxide is insoluble.

Iron Oxide: Why Water Won't Unlock Steel

To attack a layer of rust, it must be dissolved. OjoAvizor cites common household acidic substances—vinegar, lemon juice, cola soda—and peine oils (Type 3 in 1), combined with mechanical impacts to fracture the layer, which sometimes acts like a true weld between parts.

Each Mechanism Demands Its Lubricant: Oil, Grease, or Graphite

There is no universal product. Greasing a motorcycle chain, a fan shaft, or a screw operating at 200º is not the same. The repertoire mentioned by Vanderwilde includes sewing machine oil, mineral oils of various viscosities, silicone and Teflon, and lithium, molybdenum, and copper greases. Hippy Lollas adds graphite and bronze.

Water-Based or Silicone-Based: The Other Side of the Coin

The same word is also used for personal care lubricants. CUATERBAC maintains that in this context, a water base is preferable and that silicone, though more expensive, is not necessarily better.

The debate points out that there is no universal lubricant: what works for one mechanism may not work for another.
