company news about Experts Debunk WD40 Myth for Car Belt Maintenance

That piercing screech from under your hood isn't just embarrassing—it could signal serious trouble. Many drivers facing squeaky serpentine or accessory belts have turned to a popular internet "hack": spraying WD-40 as a quick fix. But automotive experts warn this solution creates more problems than it solves.

Originally formulated as a rust penetrant and metal lubricant, WD-40 contains solvents and lightweight oils. While it may temporarily quiet a noisy belt, the product actively degrades rubber components:

• Rubber deterioration: The solvents dissolve the belt's surface layer, reducing its grip on pulleys
• Accelerated aging: Oils penetrate the rubber matrix, causing swelling and eventual cracking
• Safety risk: Compromised belts can snap unexpectedly, potentially leaving drivers stranded

Automotive technicians recommend these evidence-based practices for belt care:

1. Regular Visual Inspections

   Examine belts monthly for:

   • Glazing (shiny surfaces indicating slippage)
   • Cracks deeper than 1/16 inch
   • Missing ribs or chunks of material
   • Contamination from oil or coolant leaks
2. Professional Belt Conditioners

   Specialty belt dressings clean surfaces without damaging rubber compounds. These water-based formulas:

   • Remove debris that causes noise
   • Restore optimal friction coefficients
   • Contain UV inhibitors to prevent dry rot
3. Engine Bay Hygiene

   A clean compartment prevents premature wear:

   • Degrease pulleys and mounting hardware
   • Check for misaligned components
   • Verify proper tension (most belts require 1/2" deflection at midpoint)

Modern multi-rib belts typically last 60,000-100,000 miles, but improper maintenance can halve this lifespan. When in doubt, consult a certified mechanic rather than relying on unverified internet remedies.
