Buying advice

When choosing a belt dressing, consider the age and material of your belts; silicone-based dressings work best for silicone belts, while rubber conditioners are ideal for older rubber belts. Ensure the product is compatible with serpentine belts if needed. Apply sparingly to avoid build-up and always follow manufacturer instructions. If noise persists after treatment, the belt may need replacement.
