Sunbrella Care

Sunbrella Marine fabrics are designed for durability in harsh saltwater environments, resisting UV fading, mildew, and water penetration while remaining breathable. Regular maintenance keeps them looking new and extends their lifespan (typically 5–10 years or more with proper care). Always test cleaning solutions on a small, inconspicuous area first. For best results, follow these steps based on official Sunbrella guidelines.

• Hose Down Regularly: Rinse with fresh water weekly (or after every outing) to remove salt, dirt, and debris. Use low pressure to avoid damaging threads. This prevents buildup and reduces the need for deep cleaning.
• Brush Off Loose Dirt: Use a soft-bristle brush to gently remove surface dust or pollen before rinsing.
• Air Dry Completely: Never fold or store wet fabric, as this can promote mildew on trapped dirt (though Sunbrella itself resists mildew growth).

1. Prepare Solution: Mix 1/4 cup mild soap (e.g., Woolite®, Dawn® dishwashing liquid, or Sunbrella Clean™ Multi-Purpose Fabric Cleaner) per gallon of lukewarm water.
2. Apply and Scrub: Spray or soak the fabric. Use a soft-bristle brush to clean in sections, working the solution into the weave. For tough stains, let it soak for 15 minutes.
3. Rinse Thoroughly: Hose off all soap residue with clear water until the water runs clear—residual soap can attract dirt.
4. Air Dry: Allow to dry fully in a shaded, well-ventilated area (avoid direct sun to prevent uneven drying).
5. Retreat for Protection: Once dry, apply a fabric protector like 303 Fabric Guard® following label instructions. Reapply annually or after deep cleaning to restore water repellency.

• For Mildew or Mold: Use a diluted bleach solution (1/2 cup bleach per gallon of water) if needed, but only after testing. Rinse immediately and retreat.
• For Oil/Grease: Blot excess, then clean with mild soap; avoid solvents.
• For Vinyl or Upholstery Areas: Use Sunbrella Marine Clean™ Multi-Purpose Boat Wash for safe, all-in-one cleaning on mixed surfaces.

• Remove and store indoors during off-season in a cool, dry place.
• If leaving on the boat, cover with breathable tarps to protect from environmental exposure.

Sunbrella is bleach-cleanable and resilient, but harsh chemicals can damage the acrylic fibers, reduce UV resistance, or strip protective coatings. Avoid these everyday items, which might seem convenient but can cause fading, weakening, or residue buildup:

Products to Avoid and Why It Harms SunbrellaSafer AlternativeBleach (Undiluted or Frequent Use)Can weaken fibers over time if not rinsed properly; not for routine cleaning.  Diluted bleach solution (1/2 cup per gallon) only for mildew, followed by thorough rinse.  Dry Cleaning SolventsStrips water-repellent finish and causes shrinkage.  Mild soap and water or Sunbrella-specific cleaners.  High-Pressure WashersForces dirt deeper into the weave or damages threads.  Low-pressure hose (under 40 PSI). Abrasive Cleaners/Scrubbers Scratches the surface, reducing stain resistance. Soft-bristle brush or sponge.  Fabric Softeners Leaves residue that attracts dirt and reduces breathability.  None—stick to mild detergents.  Acetone or Paint Thinner Dissolves the acrylic coating, causing discoloration. Blot and use mild soap for spills.  Ironing or Heat Drying Melts or warps fibers; never use dryers. Air dry only.
