What is the best lubricant for zippers?

The best lubricant for zippers is typically a silicone-based lubricant, as it effectively reduces friction and prevents rust without attracting dirt. You can also use zipper-specific products or beeswax for a more natural option. Avoid using oils or greases, as they can become sticky and attract debris. Regular maintenance with these lubricants can help extend the life of your zippers.
