1. Dicor Rubber Roof Wash: Best Overall
Dicor Rubber Roof Wash is a top choice for RV owners who want a dedicated cleaner that won’t harm their rubber roof. In our evaluation based on manufacturer specs and owner feedback, it effectively removes dirt, grime, and black streaks without damaging EPDM or TPO membranes. The concentrated formula offers great value, as a single bottle can be diluted to produce up to 8 gallons of cleaning solution. Users report that it rinses cleanly and leaves no residue that could attract dirt.
However, because it is a concentrate, you need to mix it properly, which may be inconvenient for some. Those who prefer a spray-and-go product might find it less easy to use. Also, while it works well on most stains, heavy oxidation may require additional scrubbing. Skip this if you want a ready-to-use spray for quick touch-ups.
- Specifically formulated for RV rubber roofs, gentle on membranes
- Concentrated: one bottle makes up to 8 gallons
- Biodegradable and phosphate-free
Pros: Excellent cleaning power without harsh chemicals; Trusted brand among RV owners
Cons: Requires dilution, not ready-to-use
2. Thetford RV Roof Cleaner: Best Ready-to-Use
Thetford RV Roof Cleaner is a convenient ready-to-use formula that we found ideal for quick cleanings. Based on owner feedback, it effectively lifts dirt and black streaks without scrubbing too hard. The spray bottle makes application straightforward, and it is safe for EPDM, TPO, fiberglass, and aluminum, so you can use it on other parts of your RV as well. Many users appreciate that it doesn’t require rinsing, though we recommend rinsing to avoid residue.
On the downside, the 32 oz bottle may not be enough for a large RV roof, requiring multiple bottles per wash. It also tends to be less effective on heavy oxidation compared to concentrated formulas. If you have a small RV or just need spot cleaning, this is a great pick; for full roof maintenance on a large rig, consider a concentrate instead.
- No mixing required, spray directly on roof
- Safe for rubber, fiberglass, and aluminum roofs
- Removes dirt, grime, and black streaks
Pros: Convenient spray bottle for easy application; All-around, works on multiple roof types
Cons: Smaller bottle may not cover large roofs in one go
3. Camco 40252 Rubber Roof Cleaner: Best Value
Camco 40252 offers a budget-friendly option without sacrificing safety. In our research, it meets industry standards for EPDM roofs and is biodegradable. When diluted according to instructions, it produces a large volume of cleaner, making it among the most cost-effective choices for regular maintenance. Owner reviews highlight its effectiveness on general grime and its mild scent.
However, some users note that it struggles with stubborn black streaks and mold, requiring extra elbow grease. It also lacks the brand recognition of Dicor or Thetford among veteran RVers. If you are on a tight budget and don’t mind a bit more scrubbing, this is a solid choice. Skip it if you need a heavy-duty cleaner for neglected roofs.
- Affordable concentrated formula
- Biodegradable and low-VOC
- Compatible with most RV rubber roofs
Pros: Great value for the price per gallon mixed; Environmentally friendly ingredients
Cons: May require more scrubbing for tough stains
4. Star brite RV Rubber Roof Cleaner: Best for Heavy Stains
Star brite RV Rubber Roof Cleaner is designed for those tough cleaning jobs. Based on manufacturer claims and owner reviews, it penetrates heavy grime and oxidation more effectively than many competitors. The ready-to-use spray format saves time, and users report that it cuts through black streaks with little effort. It is also safe for both EPDM and TPO, which adds versatility.
However, this performance comes at a premium, making it less economical for frequent whole-roof washes. Some users also note that it can be a bit harsh on skin, so gloves are recommended. If you have a heavily soiled roof or need to remove stubborn stains, this is a strong option. For routine maintenance, a concentrate might offer better value.
- Powerful formula for tough stains and oxidation
- Spray-on, no scrubbing required for light dirt
- Safe for EPDM and TPO roofs
Pros: Excellent at removing black streaks and bird droppings; Works quickly with minimal scrubbing
Cons: Higher price per ounce compared to concentrates
5. 303 Multi-Surface Cleaner: Best Multi-Surface
303 Multi-Surface Cleaner is a popular choice among RV owners who want a single cleaner for multiple surfaces. In our evaluation, it is safe for rubber roofs and does not damage seals or gaskets. It cleans light dirt and dust effectively and leaves a clean finish. Many owners use it for quick wipe-downs between deep cleans.
However, for heavily soiled roofs with years of grime, it may require multiple applications or extra scrubbing. It is not formulated specifically for RV roofs, so its cleaning power is limited compared to dedicated products. If you prefer simplicity and have a well-maintained roof, this is convenient. Skip it if your roof has significant staining or oxidation.
- Multi-purpose cleaner for roof, seals, and exterior
- Non-abrasive and non-streaking
- Can be used on rubber, plastic, and vinyl
Pros: Multi-purpose, reduces number of products needed; Gentle formula safe for seals and gaskets
Cons: Not as strong on heavy roof grime as dedicated products
6. RV Care Rubber Roof Cleaner: Eco-Friendly Pick
RV Care Rubber Roof Cleaner stands out for its eco-friendly formulation. We researched its ingredients and found they are plant-based and biodegradable, meeting strict environmental standards. It effectively cleans light to moderate dirt and is safe for all rubber roof types. Owner feedback indicates it works well for regular maintenance and rinses cleanly.
However, the 16 oz bottle is smaller than most concentrates, yielding only 4 gallons of cleaner. This makes it less economical for large roofs. It also requires more product for tough stains. If you prioritize environmental impact and have a smaller RV, this is a good choice. For heavy cleaning or large rigs, you may need a more potent option.
- Plant-based and biodegradable formula
- Concentrated, makes up to 4 gallons
- Safe for EPDM and TPO roofs
Pros: Environmentally friendly ingredients; Mild scent, pleasant to use
Cons: Small bottle, less value per gallon than other concentrates
7. Meguiar's M4916 RV One Step Cleaner Wax: Best All-in-One
Meguiar’s M4916 is a popular cleaner wax for RV exteriors, but it is important to note that it is not designed for rubber roofs. In our research, manufacturer instructions explicitly state it is for fiberglass and painted surfaces. Using it on EPDM or TPO can lead to deterioration or residue. Some owners mistakenly use it on rubber and report issues.
For those with fiberglass roofs, this product performs well, cleaning and protecting in one step. However, given our focus on rubber roof cleaners, this product is not recommended for that purpose. It is included to highlight that not all RV cleaners are suitable for rubber. Skip this if you have a rubber roof; choose a dedicated rubber cleaner instead.
- Cleans and waxes in one step
- Provides UV protection
- Best for fiberglass roofs, not recommended for rubber
Pros: Adds shine and protection after cleaning; Great for fiberglass sections
Cons: Not safe for rubber roofs, may cause damage
Frequently Asked Questions
Can I use a pressure washer on my RV rubber roof?
Yes, but with caution. Use a wide fan tip (40 degrees or wider) and keep the pressure under 1,200 psi to avoid damaging the membrane or seals. Never use a zero-degree tip or hold the nozzle too close. Many manufacturers recommend using a low-pressure setting to prevent lifting the edges of the roof.
How often should I clean my RV rubber roof?
Most manufacturers recommend cleaning at least twice a year, but more frequent cleaning may be needed if you park under trees or in areas with heavy bird droppings. Regular cleaning prevents buildup that can degrade the rubber over time. Always follow the cleaner’s instructions for best results.
Is it safe to use bleach or household cleaners on my rubber roof?
No. Bleach and many household cleaners contain harsh chemicals that can dry out and crack rubber roofing. They also void warranties. Always use a cleaner specifically formulated for RV rubber roofs, which are pH-balanced and safe for EPDM and TPO membranes.
What is the difference between EPDM and TPO roofs?
EPDM (ethylene propylene diene monomer) is a synthetic rubber that is flexible and durable. TPO (thermoplastic polyolefin) is a single-ply membrane that is heat-welded and more resistant to UV. Most rubber roof cleaners are safe for both, but always check the label. TPO can be more sensitive to some chemicals, so stick to products that explicitly list TPO compatibility.
Do I need to apply a protective coating after cleaning?
Not always, but it can extend the life of your roof. Some cleaners contain UV protectants. For maximum longevity, consider applying a rubber roof conditioner or UV protectant after cleaning. This helps prevent cracking and fading. Many owners use 303 Aerospace Protectant or a dedicated RV roof conditioner.
Our Verdict
After researching and comparing the top RV rubber roof cleaners, we found Dicor Rubber Roof Wash to be the best overall due to its proven performance, safety for both EPDM and TPO, and excellent value as a concentrate. For those who prefer a ready-to-use spray, Thetford RV Roof Cleaner is a strong runner-up with great convenience. Always choose a cleaner that matches your roof type and cleaning needs.
