No, you should never use WD40 on an old clock. Using WD40 on the delicate mechanisms or metal parts of an antique or old clock can cause significant, irreversible damage.
Why WD40 is Detrimental to Old Clocks
WD40, while a popular household product for many uses, is not a suitable substance for the intricate and precise movements found in old or antique clocks. It is primarily a water displacer and penetrant, not a long-term lubricant designed for fine clockwork.
Here's why WD40 is harmful:
- Seepage into Mechanisms: WD40 is very thin and can easily seep into the microscopic crevices and delicate moving parts of a clock's mechanism. This can displace existing, proper lubricants and introduce contaminants.
- Damage and Erosion: Over time, the components of WD40 can dry out, become gummy, and attract dust and grime. This sticky residue can hinder the clock's movement, causing excessive wear and potentially destroying or eroding valuable, essential parts within the clock's movement. It is particularly known for seeping into the moving mechanisms and causing serious damage.
- Not a Proper Lubricant: Clocks require specialized, high-grade oils and greases that are carefully applied to specific pivot points and gears. WD40 is not formulated for this purpose and will not provide the necessary, long-lasting lubrication.
- Attracts Contaminants: The film left by WD40 can attract and hold dust, dirt, and other airborne particles, forming an abrasive paste that grinds down the delicate brass and steel components, leading to accelerated wear.
- Discoloration and Residue: It can also leave behind an unsightly residue on metal surfaces and may even discolor or damage finishes on the clock's frame or case.
Using metal polishes should also be avoided for any metal parts and framing on your clock, as they too can seep into the moving mechanisms and cause damage.
Proper Care for Antique and Old Clocks
Instead of WD40 or metal polishes, proper maintenance for an old clock involves specialized care and, most importantly, professional attention.
Do's and Don'ts for Old Clock Maintenance
To ensure the longevity and accurate functioning of your cherished timepiece, follow these guidelines:
| Aspect | Do | Don't |
|---|---|---|
| Internal Care | Seek professional servicing every 5-7 years from a qualified clockmaker. | Use WD40, metal polishes, or any household lubricants on internal parts or external framing. |
| Dusting | Gently dust the exterior of the clock with a soft, lint-free cloth. | Use abrasive cloths, brushes, or harsh cleaning agents. |
| Cleaning Case | Use appropriate, gentle cleaners specifically designed for the case material (wood, brass, glass), applied only to the exterior. | Allow liquids to seep into any openings or mechanisms. |
| Lubrication | Leave all internal lubrication to a professional clockmaker during servicing. | Apply any oils, greases, or lubricants yourself. |
| Movement | Handle the clock with extreme care; avoid sudden movements or tilting. | Disassemble any part of the clock's movement without professional knowledge. |
| Placement | Place the clock on a stable, level surface, away from direct sunlight, humidity, or drafts. | Place near vents, heaters, or in areas with fluctuating temperatures. |
For more general advice on maintaining your antique clock, you can consult reputable horological associations or conservation guides from museums. A reliable source for general antique clock care can provide further insights into preserving these historical artifacts.
When to Consult a Professional
It's crucial to consult a professional clockmaker or horologist if your old clock exhibits any of the following signs:
- The clock stops or runs intermittently.
- It is not keeping accurate time.
- You hear unusual noises from the mechanism.
- The chimes or strike do not function correctly.
- Visible dirt, corrosion, or wear on internal components.
A professional will have the specialized tools, knowledge, and appropriate lubricants to clean, repair, and maintain your old clock without causing damage.
