How to Clean and Store Trailer Tarps for Longevity

Trailer tarps face a barrage of elements, including dirt, UV rays, and moisture. If left untreated, debris can weaken the tarp’s fabric, UV exposure can cause cracking, and moisture can lead to mildew and mold. Routine cleaning not only extends their lifespan but also ensures they function properly to protect valuable cargo.

Step-by-Step Cleaning Guide for Trailer Tarps

1. Shake Off Loose Dirt and Debris

Before you dive into scrubbing, give your tarp a good shake or use a soft broom to remove loose dirt and debris. You’d be surprised how much grit and grime can accumulate on long hauls.

Tip: Be gentle with the sweeping to avoid micro-tears or fraying.

2. Rinse Thoroughly

Set up your tarp on a clean, flat surface or hang it using a secure structure. Use a low-pressure water hose to rinse off surface dirt. Avoid using high-pressure washers, as they can damage the fabric or protective coatings.

3. Apply a Cleaning Solution

A mix of warm water and a mild detergent works wonders. Avoid harsh chemicals like bleach or ammonia, which can degrade the tarp’s UV protection and waterproof coating. Gently scrub with a soft-bristle brush or a sponge.

DIY Cleaning Mix:

• 1 gallon of warm water
• 1 tablespoon of mild dish soap
• Optional: Add 1 cup of white vinegar for mold prevention

4. Address Stubborn Stains

For stubborn stains, use a dedicated tarp cleaner or a mild degreaser. Focus on areas with oil, grease, or road tar buildup. Scrub in circular motions, but don’t overdo it—excessive scrubbing can wear down the fabric.

5. Rinse and Inspect

Thoroughly rinse off the cleaning solution to avoid soap residue buildup, which can attract dirt over time. While rinsing, inspect the tarp for any signs of wear, small tears, or frayed seams. Spotting these early can save you from costly replacements later.

6. Drying Is Key

A common mistake is rolling up a damp tarp, which invites mold and mildew growth. Lay the tarp flat or hang it in a shaded, well-ventilated area to air dry completely. Avoid direct sunlight during drying, as prolonged exposure can cause UV damage.

How to Store Trailer Tarps for Maximum Longevity

Storing your tarp properly is just as important as cleaning it. Improper storage can lead to cracks, stiffness, and unpleasant odors.

1. Fold or Roll It Neatly

Once your tarp is dry, fold or roll it neatly. Rolling is often preferred, as it prevents hard creases that could weaken the material over time.

Pro Tip: Use the “accordion fold” method to avoid creating sharp creases in PVC or vinyl tarps.

2. Choose the Right Storage Location

Store your tarp in a cool, dry place away from direct sunlight and extreme temperatures. Basements, garages, or dedicated storage bins work best. Avoid leaving it in the back of your trailer for extended periods—humidity buildup can wreak havoc.

3. Use Protective Covers

Consider placing the folded or rolled tarp inside a protective cover or storage bag. This will shield it from dust, pests, and potential punctures.

4. Regularly Inspect Stored Tarps

Just because a tarp is in storage doesn’t mean you can forget about it. Every few months, inspect it for signs of mold, mildew, or fabric deterioration. If issues arise, address them immediately to prevent further damage.

Common Mistakes to Avoid

• Skipping the rinse: Soap residue attracts dirt, which accelerates wear.
• Using harsh cleaners: Chemicals like bleach can strip away UV and waterproof coatings.
• Storing damp tarps: Moisture leads to mold, mildew, and fabric decay.
• Neglecting small repairs: Tiny tears grow fast under pressure.

Repairing Minor Damage

During inspections, if you find small holes, rips, or frayed seams, don’t ignore them. Use a tarp repair kit or heavy-duty adhesive patches to address the damage before it worsens. For larger tears, professional repair services, like those offered by Skip's The Rolling Tarp Specialists in North Carolina, can restore your tarp’s functionality.

When to Replace Your Trailer Tarp

Even with the best care, trailer tarps won’t last forever. If you notice thinning fabric, large cracks, or irreparable tears, it’s time to consider a replacement. A damaged tarp puts your cargo and reputation at risk—better safe than sorry.
