🧼 What is WeatherShield®?

WeatherShield is a solution-dyed polyester with a urethane backing, giving it:

• Superior water resistance

• Mold & mildew defense

• High UV durability

• Minimal shrink/stretch issues

• Exceptional tear & abrasion resistance

But even with all those superpowers, regular cleaning and occasional re-treatment is essential for long-term performance.

What You’ll Need

• ✅ 303 Multi-Surface Cleaner, 32 oz

🧽 Step 1: Regular Cleaning

For standard dirt, dust, or light stains, follow this process:

1. Mix your solution – Combine 2 oz. of mild soap with 1 gallon of lukewarm water.

2. Apply and scrub – Use a soft brush or cloth to gently clean the non-coated (outer) surface.

3. Rinse thoroughly – Use clean, cold water to rinse off soap and dirt.

4. Air dry – Let the cover dry completely before reapplying protectants.

Alternatively, you can use 303 Multi-Surface Cleaner for a more powerful, ready-to-use option:

• Spray directly on the surface

• Scrub lightly with a soft brush

• Rinse and dry

🧴 Step 2: Treating Stubborn Stains

If you’re dealing with mildew or set-in grime:

1. Mix 1 cup of bleach with 1 gallon of water (max concentration).

2. Lightly spray the solution on the outer (non-coated) surface. Do not soak the fabric.

3. Let sit for no more than 2 minutes.

4. Rinse thoroughly and dry completely.

⚠️ Note: Bleach will strip the protective finish—so you’ll need to re-treat with a fabric guard afterward.

☀️ Step 3: Restore Water Repellency

After any deep clean or bleach treatment, restore the water-repellent finish with 303 Fabric Guard:

1. Ensure fabric is completely dry before applying.

2. Spray evenly over the entire outer surface until damp, not soaked.

3. Allow to air cure for 6–12 hours in a clean, dry space.

4. Water-test by spraying a few drops—if it beads, you’re good!

🏆 Why 303 Fabric Guard?
