- pH-Balanced
A pH-balanced formula is gentle on the fiberglass. I’ve noticed that cleaners with this feature help maintain the integrity of the surface while still being tough on stains.
- Mildew and Mold Prevention
Since bathrooms are humid environments, I prefer cleaners that not only clean but also inhibit the growth of mold and mildew. This keeps my shower looking fresh for longer periods.
- Ease of Use
I appreciate products that are easy to apply—whether it’s a spray, foam, or wipe. A cleaner that doesn’t require excessive scrubbing saves me time and effort.
- Pleasant Fragrance
Let’s face it, a cleaner that smells good makes the whole experience better. I tend to lean towards products with fresh scents that leave my shower smelling great after cleaning.

When I clean, I always use a soft cloth or sponge to avoid scratching the fiberglass. Microfiber cloths work best for me.
- Rinse Thoroughly
After using any cleaner, I ensure to rinse the shower thoroughly. This step prevents any residue that might dull the finish over time.
- Ventilation
Keeping the bathroom well-ventilated helps reduce moisture, which in turn helps prevent mold and mildew. I always leave the bathroom door and window open if possible.
