Lubricants for an Aluminum Mechanism

For lubricating an aluminum mechanism with a clicking function, here are a few options along with their pros and cons:

Dry Lubricants (e.g., PTFE, Graphite, Molybdenum Disulfide)

• Pros: Doesn’t attract dust, long-lasting, good for fine mechanisms.
• Cons: May not provide as much friction reduction as wet lubricants.

Silicone Lubricants

• Pros: Safe on aluminum, non-corrosive, good for light mechanisms.
• Cons: Can be messy, may not last long under heavy use.

Lithium Grease

• Pros: Stays in place, good for moderate load applications.
• Cons: Can be too thick for small, delicate mechanisms.

WD-40 (or similar water-displacing spray)

• Pros: Quick fix, helps free stuck parts.
• Cons: Not a long-term lubricant, can attract dirt over time.

Machine Oil (e.g., 3-in-1, mineral oil, synthetic oils)

• Pros: Thin and precise, good for small mechanisms.
• Cons: Can attract dust, may require reapplication.

If dust accumulation is a concern, go with dry lubricants. If you need smooth movement and don’t mind some residue, silicone or machine oil are good choices. Avoid WD-40 as a long-term solution—it's more of a cleaner than a true lubricant.

Using WD-40 Before a Dry Lubricant

If you apply WD-40 first and then follow up with a dry lubricant, the WD-40 can interfere with the dry lubricant’s ability to adhere properly. WD-40 leaves a residue that can prevent the dry lubricant (like PTFE or graphite) from fully bonding to the surface, reducing its effectiveness.

To make this work, you’d need to fully clean off the WD-40 with a degreaser or isopropyl alcohol before applying the dry lubricant. Otherwise, the combination might just attract dust and grime while not providing the benefits of either lubricant.
