Fortunately, it is possible to remove these streaks, and you can do it with minimal effort too. Keep reading this article to know how to clean them effectively and everything related.

Why do Black Streaks Appear on RVs?

There are different reasons behind the appearance of these black streaks on campers. Sometimes they are caused by the chalky material that appears after RV roofing material sheds. Black streaks also occur because of the rain that pours down from the roof and brings dirt with it.

No matter how clean an RV is, if it is left unchecked, it will accumulate black streaks. They will get darker and entrenched with time if the RV isn’t cleaned.

How to Remove Black Streaks from Your RV?

The black streaks on your RV can be both old and new. Unfortunately, the methods that remove fresh streaks cannot work on the older ones. So, you need to remove them using different materials and techniques.

The unsightly black streaks on your RV, whether they’re a recent nuisance or have been persisting for a while, can certainly detract from its appearance.

Regrettably, the techniques effective in eliminating fresh streaks may not prove successful for those more stubborn older ones. Therefore, it’s essential to employ diverse materials and methods – similar to how you would approach removing decals from your RV – to restore your vehicle’s pristine look.

Removing New Streaks

You can easily remove fresh RV streaks using regular soap and water. Newer streaks come off easily, so you do not have to buy expensive cleaners for them.

You need to get a sponge, soak it in soapy water, and rub it over your RV. Some higher spots might be inaccessible, but you can use an RV brush to reach up there and clean them thoroughly.

After diligently sponging away at the streaks, give your vehicle a good rinse with a hose to wash away any lingering dust or debris. This simple method ensures that both your RV and its awning are left sparkling clean without breaking the bank.

Effortlessly eliminate fresh RV streaks using nothing more than everyday soap and water. These newer marks tend to be easily removable, negating the need for costly cleaning solutions.

To begin the process, equip yourself with a sponge, drench it in soapy water, and gently scrub over your RV. For those harder-to-reach spots on your RV awning, an RV brush can prove invaluable in ensuring a thorough clean.

Removing Older Streaks

Older streaks are harder to remove and require much more effort from you. The black streaks become semi-permanent due to sun rays, especially if you do not clean your RV for a long time. Soap and water will not do the job anymore, so you will need a quality RV cleanser.

Ensure that the cleanser you buy is non-flammable and non-toxic to avoid any mishaps during cleaning.

Homemade RV Black Streak Removers

Use a sponge to rub this mixture on black streaks. Start with a small area to check its effectiveness and make more of it if all works well.

White Vinegar

Vinegar is not only an excellent household ingredient but can also be effective in cleaning your RV. When black streaks oxidize after some time, white vinegar is the best weapon to fight them. For every gallon of water, use 3 cups of vinegar.

You can apply it using sponges or RV pressure washers. Let it sit on the surface for a few minutes before washing it off. Then, rinse the whole area thoroughly to have no vinegar left. If you do not remove it completely, vinegar can damage the surface of your RV and fade it too.

WD-40

Wash your RV before applying WD-40 and let it sit there for a few minutes. Then, use soap and water to wash it off completely.

Removing black streaks from your camper isn’t hard, but preventing it in the first place is even better. There are a few things you can do to minimize the appearance of these pesky streaks on your RV.

Keep the Roof Clean

The biggest reason behind black streaks on your RV is the dirty roof. It results in dirty rainwater all over your RV. keep the roof clean using soap and water regularly to avoid the buildup of dust and debris. Do not use any abrasive cleaners because they can damage the roof of your RV.

Not many people try it, but waxing your RV can be a great way to avoid the streak buildup. Waxing provides a layer of protection that keeps dust and rainwater away from the actual RV surface beneath it. 

Clean AC Drain Pipes

The condensation of air conditioners can sometimes spill to the sides of your RV. Most RVs have special gutters to avoid this problem but curbing it completely isn’t possible. The water coming out of the condensation is often dirty and leaves streaks on the RV.

You can clean the gutters with a microfiber cloth. If the gutters have some hardened spots, try removing them using a toothbrush. Cleaning them also helps the water back up and prevents excessive dirt buildup.

Cover your RV

Cover your RV when it is not used to ensure it remains clean. People often park their RVs in storage facilities during winter, where they can get dirty. A cover can keep dirt, debris, and water away from your RV.

Use of Pressure Washer
