Umbrella care after rain: dry it before folding
Gently remove rainwater, leave the canopy open to dry completely, and store only when dry. Avoid detergents and high heat.
Fulton recommends opening a wet umbrella to dry as soon as possible and wiping marks with a soft cloth dampened with plain water. BLUNT and Fox Umbrellas also emphasize drying fully before storing. Specific product instructions take precedence.
