Buying Guide
Choosing the right cleaner for your fiberglass camper depends on a few factors. Consider these points before making a purchase:
- Type of Cleaning: Do you need a heavy-duty cleaner for stubborn stains, or a gentle wash for regular maintenance?
- Protection: Do you want a cleaner that also provides wax protection or UV protection?
- Environmental Concerns: Are you looking for an eco-friendly and biodegradable option?
- Surface Compatibility: Make sure the cleaner is safe for gel coat and fiberglass surfaces.
- Ease of Use: Consider the application method and rinsing requirements.
Also, always test a new cleaner in an inconspicuous area first to ensure it doesn’t damage or discolor the surface.
For heavy oxidation, you might need a dedicated oxidation remover before using any of these cleaners. And don’t forget to use a good quality wash mitt or sponge to avoid scratching the fiberglass.
