A waterproof ATV cover is designed to protect your ATV from harsh weather, UV rays, rain, dust, and debris. However, many ATV owners do not realize that the cover itself also needs maintenance. Dirt, mud, and moisture can reduce the effectiveness of the waterproof coating over time.

This detailed guide explains how to clean a waterproof ATV cover safely, how to prevent damage during cleaning, and how to increase the lifespan of your cover. Whether your ATV cover is made of 600D Oxford, 420D polyester, ripstop fabric, PVC-coated material, or PU-coated cloth, the cleaning process matters for long-term durability.

Why Cleaning a Waterproof ATV Cover Matters

A waterproof ATV cover goes through daily exposure to outdoor elements. Without regular cleaning, it collects:

• Mud and dirt
• Tree sap and pollen
• Bird droppings
• Road dust
• Mold and mildew
• Rainwater stains
• Sun exposure-related residues

Over time, this buildup can cause:

• Reduced waterproof performance
• Fading and fabric damage
• Weakened seams
• Growth of mold or mildew
• Strong odor
• Cracked or stiff fabric

Cleaning the cover extends product lifespan and helps the ATV stay protected year-round.

How Often Should You Clean Your ATV Cover?

The cleaning frequency depends on where and how the ATV is stored:

1. Outdoor Storage (Open Area)

Clean every 4–6 weeks because exposure to rain and dust is higher.

2. Semi-Outdoor Storage (Carport, Shed, Tarp Roof)

Clean every 6–8 weeks.

3. Indoor Garage Storage

Clean every 3–4 months, depending on dust buildup.

4. After Heavy Rain or Mud Exposure

Rinse the cover as soon as possible to prevent stains and odor.

5. Before Long-Term Storage (Seasonal / Winter Storage)

Always clean and air-dry completely before packing the cover away.

Tools and Materials Needed

Before you start, gather these safe cleaning supplies:

• Mild liquid soap (non-detergent, non-bleach)
• Bucket of clean water
• Soft sponge
• Microfiber cloth
• Soft-bristle brush (optional)
• Hose with low water pressure
• Vinegar (for mold removal, optional)
• Clean open area for drying

Important: Avoid bleach, strong detergents, solvents, or high-pressure washers. These can damage the waterproof coating instantly.

How to Clean a Waterproof ATV Cover – Step-by-Step Guide

This method works for all waterproof covers, including 600D, 420D, PVC-coated, PU-coated, and ripstop covers.

Step 1: Remove Loose Dirt and Debris

Take the ATV cover off the vehicle. Shake it gently to remove:

• Dry dirt
• Dust
• Leaves
• Sand
• Small debris

This prevents scratches when cleaning.

Step 2: Rinse With Low-Pressure Water

Lay the cover on a clean surface.

Use a hose with gentle pressure to rinse off mud and dirt.

Avoid:

• Pressure washers
• Hot water
• High-pressure jets

These can weaken seams and strip waterproof layers.

Step 3: Prepare a Mild Soap Solution

In a bucket, mix:

• Clean water
• A small amount of mild soap or gentle dish soap

Make sure the soap contains no bleach, no harsh chemicals, and no fabric softeners.

This ensures the waterproof coating stays intact.

Step 4: Gently Wash the Cover

Dip a sponge or microfiber cloth in the soap mixture and clean the cover using slow circular motions.

Focus on areas where dirt usually sticks:

• Top section (roof area)
• Elastic hem
• Corners
• Straps and buckles
• Vent openings

For stuck dirt, use a soft-bristle brush—but avoid scrubbing too hard.

Step 5: Rinse Thoroughly

Rinse the entire cover with clean water until no soap remains.

Soap residue can:

• Attract more dirt
• Damage waterproof coating
• Create a sticky surface

So thorough rinsing is important.

Step 6: Air-Dry the Cover Fully

This is a crucial step.

Hang the cover on a clothesline or over an open surface and let it air-dry naturally.

Avoid:

• Direct strong sunlight for long hours
• Machine drying
• Heat sources

High heat can damage waterproof layers or shrink the fabric.

Make sure the cover is 100% dry before storing.

Moisture trapped inside can lead to mold and unpleasant smell.

How to Remove Mold, Mildew, or Bad Odors

If the cover has mildew spots:

Vinegar Cleaning Method

1. Mix 1 cup white vinegar with 4 cups water.
2. Apply the solution to the affected area.
3. Gently scrub with a soft cloth.
4. Let it sit for 10 minutes.
5. Rinse thoroughly.
6. Air-dry completely.

Vinegar is safe and does not damage the waterproof layer.

Things You Should Never Use on a Waterproof ATV Cover

To protect the waterproof coating, avoid:

• Bleach
• Laundry detergent with strong chemicals
• Solvents or alcohol-based cleaners
• Pressure washers
• Fabric softeners
• Machine washing
• Hot dryer
• Rough brushes

These can cause cracking, fading, or permanent loss of waterproof ability.

Protecting the Waterproof Layer After Cleaning

Over time, the waterproof layer on any cover starts wearing down. To maintain it:

Reapply Waterproof Spray Every 6–12 Months

Use fabric waterproof spray designed for:

• Outdoor gear
• Tents
• Jackets
• Marine covers

This renews the water-repellent surface and improves longevity.

Make sure the cover is clean and dry before application.

How to Store Your Waterproof ATV Cover Properly

Proper storage increases lifespan:

• Fold the cover neatly
• Store in a dry, cool place
• Avoid damp areas
• Use the original storage bag if available
• Never store it when damp

This prevents mold growth and material weakening.

Signs That Your ATV Cover May Need Replacement

Even with proper care, ATV covers eventually wear out. Consider replacing if you notice:

• Cracked or peeling material
• Fading that exposes inner layer
• Water leaking through after rain
• Weak or broken seams
• Large tears
• Elastic hem losing stretch
• Persistent mold odor

If the waterproof layer no longer works, the ATV is left unprotected.

Conclusion

Cleaning a waterproof ATV cover is simple but very important. With the correct cleaning method, you can:

• Maintain waterproof performance
• Increase fabric durability
• Prevent mold and odor
• Extend the cover’s lifespan
• Ensure maximum protection for your ATV

By following these steps regularly, your cover will continue to shield your ATV against rain, dust, UV rays, and harsh outdoor conditions.
