Frequently Asked Questions
Are water-repellent cushion covers fully waterproof?
No — most cushion covers labeled water-repellent shed light rain and spills but are not fully waterproof for long, heavy downpours. For complete protection, use a dedicated waterproof cover or store cushions indoors during storms. Water-repellent fabrics are better at keeping surfaces dry and reducing mildew risk in everyday conditions.
How do I prevent mildew on outdoor cushions?
Keep cushions clean and dry: brush off debris, spot-clean spills promptly, and allow cushions to fully dry before re-covering. Use breathable, water-repellent covers and avoid trapping moisture by airing cushions occasionally. For long-term storage, keep cushions in a dry, ventilated place.
Will washing reduce the water repellency of these covers?
Frequent machine washing or using hot water and harsh detergents can degrade water-repellent coatings. Follow the care instructions—spot clean or hand wash in cold water and air dry to preserve the protective finish. Reapply a spray-on water repellent if needed after many washes.
