1. Thetford Premium RV Wash and Wax: Top Pick for All-Around Performance
The Thetford Premium RV Wash and Wax is a concentrated cleaner that we found to be highly effective at removing black streaks based on owner feedback. Its wash and wax formula not only cleans but also leaves a protective coating that helps prevent future streaking. In our evaluation, it performed well on fiberglass and painted surfaces without dulling the finish. Users report that it cuts through grime with less effort than many competitors.
However, because it is a concentrate, you need to mix it with water, which may not be ideal for quick touch-ups. Some owners noted that if not rinsed thoroughly, it can leave a slight film. This product is best for RV owners who want a two-in-one solution and are willing to follow dilution instructions carefully. Skip it if you prefer a ready-to-use spray for spot cleaning.
- Combines wash and wax to remove streaks while leaving a protective layer
- Biodegradable and safe for all RV surfaces including fiberglass and painted finishes
- Rinses clean without leaving residue that can attract dirt
Pros: Effective on stubborn black streaks with minimal scrubbing; Leaves a glossy shine that lasts
Cons: Requires dilution which can be inconvenient for spot cleaning
2. Meguiar's M5032 Marine/RV Heavy Duty Oxidation Remover: Best for Heavy-Duty Streaks
Meguiar’s M5032 is a heavy-duty oxidation remover that we researched for tackling the toughest black streaks. Owner feedback indicates it excels on older RVs with significant oxidation and embedded grime. The paste formula can be used by hand or with a buffer, and it effectively removes stains that other cleaners leave behind. In our evaluation, it restored a faded gel coat to a like-new shine.
However, this product is not a simple wash; it requires more physical effort and careful application. It is not recommended for clear-coated surfaces unless you follow the instructions precisely. Some users reported that if left on too long, it can dull the finish. This is best for RV owners with heavily stained or oxidized surfaces who are comfortable with a more involved process. Skip it if you want a quick, effortless wash.
- Specifically designed to remove heavy oxidation and black streaks from gel coat
- Can be applied by hand or with a dual-action polisher for deep cleaning
- Restores gloss after removing stubborn stains
Pros: Extremely effective on severe black streaks and oxidation; Professional-grade results
Cons: Requires more effort and time compared to spray-on cleaners; May be too aggressive for clear-coated finishes if used improperly
3. RV Black Streak Remover by Star brite: Best Spot Cleaner
The Star brite RV Black Streak Remover is a dedicated spot cleaner that we evaluated for its ease of use. Owner reviews highlight its convenience: spray on, let sit, then rinse. It works well on recent black streaks and general grime without damaging the RV’s finish. In our research, it was praised for being gentle yet effective on fiberglass and painted surfaces.
However, for heavily oxidized or deeply embedded streaks, it may not be strong enough on its own. Some users had to scrub more than expected. It is best for regular maintenance and light to moderate staining. Skip it if your RV has severe, long-term black streak buildup that requires a heavy-duty cleaner.
- Spray-on formula specifically for black streaks, no dilution needed
- Works on fiberglass, aluminum, and painted surfaces
- Biodegradable and phosphate-free
Pros: Convenient for quick spot cleaning of streaks; Effective on fresh to moderate stains
Cons: Less effective on very old or heavy buildup; May require multiple applications for deep stains
4. Camco RV Wash and Wax Concentrate: Best Value Concentrate
Camco’s concentrate is a budget-friendly option that we researched for its value. Owner feedback indicates it is effective for routine washing and can handle light black streaks. The large bottle makes it ideal for RV owners who wash frequently. In our evaluation, it performed adequately on moderate stains and left a decent shine.
However, for stubborn black streaks, it may not be as potent as dedicated cleaners. Some owners noted that it requires more scrubbing and careful rinsing to avoid residue. This product is best for those who want an economical all-purpose wash and wax and don’t have severe streaking issues. Skip it if you need a powerful streak remover for heavy buildup.
- Economical concentrate that provides many washes per bottle
- Formulated to remove black streaks and road grime
- Leaves a protective wax coating
Pros: Great value for the amount of cleaner you get; Works well on general dirt and light streaks
Cons: May require multiple applications for tough black streaks; Some users report it leaves a slight residue if not rinsed thoroughly
5. Chemical Guys EQP_110_16 Extreme Body Wash and Wax: Best for Gel Coat Gloss
Chemical Guys Extreme Body Wash and Wax is a popular car wash that we evaluated for RV use. Owner feedback shows it works well for general cleaning and adds a nice gloss to gel coat. It can help remove light black streaks when used with a mitt, but it is not a dedicated streak remover. In our research, it was praised for its foam and scent.
However, for heavy black streaks, it falls short compared to specialized products. The small concentrate bottle makes fewer gallons than some competitors, reducing its value. This product is best for RV owners who prioritize a glossy finish and have only minor streaking. Skip it if black streaks are your primary concern.
- High-foaming wash and wax that lifts dirt and streaks
- Safe on all RV surfaces including clear coats
- Leaves a high-gloss finish
Pros: Produces rich foam that helps loosen dirt; Enhances gloss and shine
Cons: Not specifically formulated for black streaks; may need extra effort; Small bottle size for the price
6. Turtle Wax 50734 Zip Wax Car Wash: Budget-Friendly Option
Turtle Wax Zip Wax is a classic car wash concentrate that we researched as a budget alternative. Owner feedback suggests it works for light dirt and minor streaks but is not a dedicated RV cleaner. In our evaluation, it is safe for gel coat and provides a basic wash with some wax protection. It is widely available and inexpensive.
However, for black streaks, it often requires repeated washing and scrubbing. It is not formulated to tackle the specific oxidation and rubber residue that cause streaks. This product is best for RV owners on a tight budget who wash frequently and have minimal streaking. Skip it if you need a specialized streak remover.
- Low-cost concentrate that provides many washes
- Formulated for use on cars, but safe for RV gel coat
- Contains wax for a protective finish
Pros: Very affordable for the volume; Easy to use and rinses clean
Cons: Not designed for black streaks; may struggle with tough stains; Less effective on heavy grime compared to RV-specific products

It is biodegradable and non-toxic, making it a good choice for environmentally conscious users. In our research, it performed well on fiberglass and painted surfaces without causing damage.
However, for deeply embedded or old streaks, it may not be as powerful as some competitors. Some users found they needed to apply multiple times.

Frequently Asked Questions
What causes black streaks on RVs?
Black streaks are caused by a combination of oxidized rubber from roof seals, dirt, and grime that wash down the sides of the RV during rain. They can also be from exhaust soot and road film. Over time, these substances bond to the gel coat or paint, creating dark streaks.
Can I use a regular car wash soap to remove black streaks?
Regular car wash soaps are not formulated to break down the specific compounds in black streaks. They may help with light dirt, but for effective removal, you need a dedicated RV cleaner or a heavy-duty oxidation remover. Our guide includes products specifically designed for this task.
Are these products safe for all RV surfaces?
Most RV washes and streak removers are safe for fiberglass, gel coat, and painted surfaces. However, some heavy-duty removers can be too aggressive for clear coats. Always test in a small area first and follow the manufacturer’s instructions. We have noted safety considerations for each product in our guide.
How often should I wash my RV to prevent black streaks?
Regular washing every 4-6 weeks can help prevent buildup. Using a wash and wax product adds a protective layer that makes future cleaning easier. For stubborn streaks, spot treatment with a dedicated remover as needed is effective.
Do I need to wax after using a black streak remover?
Some products combine wash and wax, so no additional wax is needed. However, if you use a heavy-duty remover that strips wax, it is recommended to apply a separate wax or sealant to protect the finish and make future cleaning easier. Check the product description for guidance.
