What Causes Those Ugly RV Black Streaks?

Those streaks aren’t just dirt. If they were, a simple rainstorm would wash them away. Instead, they’re a grimy cocktail of dissolved roofing material, residue from sealants, and environmental pollutants that stick to your rig’s siding.

Most RV roofs are made of materials like EPDM or TPO rubber, which slowly shed microscopic particles over time. When it rains, this chalky residue mixes with dust, pollen, and road grime, then runs down the sides of your RV. The sun bakes this mixture onto the finish, creating a stubborn stain that regular soap can’t touch. This is why you often see the worst streaks originating from window frames, marker lights, and roof-mounted accessories where water naturally channels.

The tradeoff for that power is its chemical strength. This isn’t a gentle, all-purpose cleaner. You have to be cautious around older, sun-faded decals, as it can sometimes cause them to lose color or peel. Always test it on a small, inconspicuous spot first. But for tough, set-in stains on fiberglass or aluminum siding, it’s hard to beat its immediate results.

Camco Pro-Strength for Heavy-Duty Cleaning

Camco is a name you see everywhere in the RV world, and their Pro-Strength Black Streak Remover is a reliable workhorse. It’s a concentrated formula designed for the specific grime that plagues RVs, cutting through grease, road film, and those dreaded streaks.

Think of this as a great all-around choice for deep cleaning your rig a few times a year. It’s effective on both fiberglass and metal siding and can even tackle tough spots like bug splatter on the front cap. Because it’s a concentrate, a single bottle goes a long way, offering good value for full-timers who need to clean often.

For many of us, living on the road is about connecting with nature, not polluting it. Bio-Kleen is the answer for the environmentally conscious RVer. It uses plant-based ingredients and is fully biodegradable, so you don’t have to worry about harsh chemicals running off into the soil at your campsite.

The honest truth? It might take a little more elbow grease than its more aggressive chemical counterparts. You may need to let it sit a bit longer or use a soft-bristle brush to agitate the really tough spots.

But the peace of mind is worth it. You get a clean rig without compromising your "leave no trace" principles. It’s also a much safer option to have around if you travel with pets or small children who might come into contact with the side of the rig.

Walk into any dollar store, and you’ll likely find a bottle of LA’s Totally Awesome. This isn’t an RV-specific product, but it has a cult following among full-time nomads for its incredible cleaning power and rock-bottom price. It’s a degreaser that melts black streaks away with shocking efficiency.

Here’s the critical part: you must dilute it. Using this stuff straight from the bottle is a recipe for disaster, as it’s strong enough to damage decals and potentially dull your rig’s clear coat. A good starting ratio is 1 part Awesome to 10 parts water, adjusting as needed.

Despite the need for caution, its versatility is unmatched. A single jug can clean your black streaks, your awning, your tires, and even greasy spots on your camp stove. For the RVer on a tight budget, it’s an indispensable tool when used correctly.

This cleaner is less about brute force and more about finesse. It safely lifts stains without threatening the integrity of your clear coat or vinyl decals.

It costs more, but it’s cheap insurance for a $10,000 paint job.

303 Aerospace Protectant Spray, UV Protection, Matte
$21.85 ($0.68 / Fl Oz)

Wet & Forget Outdoor for Set-It-and-Go Use

This one is a completely different approach. Wet & Forget isn’t an "instant" cleaner you spray and wipe. It’s a long-term solution you apply and, as the name implies, forget. You simply spray it on your roof and the top few feet of your rig on a dry, overcast day and let nature do the work.

The formula works with subsequent wind and rain to gently kill the mold, mildew, and algae that are a primary component of black streaks. It’s not for someone who needs their rig spotless by tomorrow. This is a preventative maintenance tool.

Over weeks and months, you’ll notice the streaks fading and, more importantly, not returning. Applying it to your roof once or twice a year can drastically reduce how often you have to scrub the sides of your rig. It’s the ultimate "work smarter, not harder" solution for black streak prevention.

Ultimately, the best black streak remover is the one that matches your rig’s finish, your budget, and how much time you want to spend cleaning. Whether you choose a powerful instant remover or a gentle, preventative one, the most important step comes after. Once your rig is clean, apply a quality wax or sealant—it creates a slippery surface that gives those grimy streaks nothing to hold onto, making your next cleanup that much easier.
