Q: How do I clean and store the RV Water Funnel?

A: Simply rinse the funnel with clean water after each use and allow it to air-dry completely before storing. Its compact size (10 × 8 × 5 cm) means it fits easily in a storage compartment, gear bag, or under-sink cabinet in your RV or camper van.

Q: Will this funnel hold up to outdoor sun exposure over multiple seasons?
