How do ODM manufacturers test the resistance of outdoor furniture to sunscreen stains?

ODM manufacturers rigorously test outdoor furniture for resistance to sunscreen stains to ensure durability and customer satisfaction. The process typically involves applying sunscreen products to fabric or material samples and exposing them to simulated outdoor conditions, such as UV light and humidity. Accelerated aging tests may also be conducted to evaluate long-term effects. Manufacturers assess colorfastness, material integrity, and ease of cleaning. High-quality outdoor furniture is designed to resist staining and maintain its appearance even with frequent sunscreen contact. These tests help ODM manufacturers deliver products that meet industry standards and consumer expectations for outdoor use.
