Understanding Fiberglass Cleaning Needs

When I first started caring for my boat, I quickly realized that maintaining the fiberglass surface is crucial. The marine environment can be harsh, and I noticed how dirt, grime, and stains build up over time. Understanding my specific cleaning needs helped me choose the right cleaner. I learned that some products are designed for heavy-duty cleaning, while others are suitable for regular maintenance.

Identifying the Types of Stains

Safety was paramount for me. I carefully checked the labels for any hazardous chemicals. Since I often cleaned my boat in open water, I wanted to ensure that the product I used was safe for marine life.
