Which type of detergent should be used for cleaning fiberglass hulls?

Using non-phosphate detergents for cleaning fiberglass hulls is advisable because these detergents are generally milder and less likely to damage the gel coat that protects the fiberglass. Fiberglass is a common material used in boat construction, and it requires care to maintain its integrity and appearance. Non-phosphate detergents are also environmentally friendly, reducing the risk of water pollution and harm to aquatic life, which is crucial for boaters who care about preserving the natural habitats where they operate.

Other types of detergents, such as abrasive detergents, can scratch or dull the surface of fiberglass, damaging the protective layer. Similarly, phosphate-based detergents may contain harmful chemicals that can contribute to water pollution and runoff issues. Automotive cleaning products might not be specifically formulated for marine applications and could include substances that are not suitable for use on fiberglass surfaces. Hence, selecting a non-phosphate detergent ensures both the longevity of the fiberglass and the protection of the surrounding environment.
