1. Meguiar's M5032 Marine/RV Heavy Duty Oxidation Scrub: Best for Oxidation
In our evaluation, the Meguiar’s M5032 consistently delivered the most impressive results for oxidized and dull RV exteriors. Based on owner feedback and the spec sheets, this heavy-duty oxidation scrub uses a combination of mild abrasives and cleaners to remove years of oxidation without damaging the gel coat. It can be used by hand or with a rotary buffer, and many owners report a like-new shine after just one application.
However, this product is not a one-step wash. It requires a separate wash step before application and a thorough rinse afterward. It is also not ideal for clear-coated finishes or for those who want a quick spray-on solution. Skip this if your RV has a clear coat or if you prefer a simple wash-and-wax product.
- Removes heavy oxidation and stains from gel coat and fiberglass
- Can be applied by hand or with a buffer for professional results
- Safe for all RV finishes including decals when used as directed
Pros: Excellent at restoring faded gel coat; Works quickly with minimal effort
Cons: Requires thorough rinsing to avoid residue
2. Chemical Guys CLW_101_64 Lightning Fast Car Wash and Wax: Best All-in-One
For RV owners looking to simplify their routine, the Chemical Guys Lightning Fast Car Wash and Wax offers a convenient all-in-one solution. We compared its spec sheet and owner reviews and found it effectively cleans light to moderate dirt while depositing a layer of wax for gloss and protection. The pH balanced formula is safe for all RV surfaces, including gel coat, clear coat, and decals.
However, the wax protection is temporary and may not last through heavy rain or multiple washes. Owners in dusty or harsh environments may need a separate wax or sealant for longer protection. Skip this if you need a heavy-duty cleaner for heavy oxidation or if you prefer a dedicated wax for maximum durability.
- Combines wash and wax for one-step cleaning and protection
- pH balanced formula safe for wax, sealants, and clear coats
- Produces rich foam that lifts dirt without scratching
Pros: Saves time with wash and wax in one step; Safe for all exterior surfaces including decals
Cons: Wax protection is not as durable as a dedicated wax
3. Thetford 70009 RV Wash and Wax: Best for RVs
The Thetford 70009 is a dedicated RV wash and wax that we researched extensively. According to manufacturer specs and owner feedback, it is biodegradable and safe for all RV exterior surfaces, including gel coat, fiberglass, and decals. It cleans effectively and leaves a protective wax layer that helps repel water and dirt, making future washes easier.
However, it is not designed for heavy oxidation or deep stains. Owners with severely faded or stained exteriors reported needing additional products. Skip this if your RV has significant oxidation or if you need a heavy-duty cleaner.
- Specifically formulated for RV gel coat and fiberglass
- Biodegradable and safe for the environment
- Leaves a protective wax layer that repels water and dirt
Pros: Formulated for RV surfaces, gentle on decals; Biodegradable formula
Cons: Not as effective on heavy oxidation
4. Wash Wax ALL by Aero Cosmetics: Best Waterless
For RVers who want to wash without a hose, the Aero Cosmetics Wash Wax ALL is a top waterless option. Our research shows it uses a polymer formula that cleans and waxes in one step, and it is safe for all surfaces including clear coat and decals. Owner feedback highlights its convenience for quick touch-ups and for use in areas with water restrictions.
However, it is not suitable for heavy dirt or mud, as wiping without rinsing can cause scratches. It also requires more product for larger RVs, which can increase cost per use. Skip this if your RV is frequently caked in mud or if you prefer a traditional hose wash.
- No water needed, ideal for boondocking or water restrictions
- Spray on, wipe off with microfiber cloth
- Contains polymers that provide UV protection and shine
Pros: Convenient waterless application anywhere; Leaves a glossy finish with UV protection
Cons: Not for heavily soiled or muddy RVs
5. 3M 09005 Marine Restorer and Wax: Best for Heavy Oxidation
The 3M 09005 Marine Restorer and Wax is a heavy-duty product designed for severely oxidized RV exteriors. From our evaluation of manufacturer specs and owner reviews, it effectively removes deep oxidation and stains, restoring color and gloss. It also contains wax to provide protection after cleaning.
However, the application is labor-intensive, often requiring a buffer and multiple passes. It can also be abrasive if not used carefully, potentially damaging clear coats or decals. Skip this if your RV has only light oxidation or if you prefer a gentler product.
- Restores heavily oxidized gel coat and fiberglass
- Can be used by hand or with a buffer
- Contains wax for protection after restoration
Pros: Powerful oxidation removal for severe cases; Includes wax for one-step protection
Cons: Requires significant effort and multiple applications
6. Star brite RV One Step Cleaner Wax: Best Value
The Star brite RV One Step Cleaner Wax is a budget-friendly option that combines cleaning and waxing. Based on owner feedback and the spec sheet, it handles light to moderate oxidation and leaves a decent wax layer. It is safe for all RV surfaces and can be applied by hand or buffer, making it accessible for DIYers.
However, it struggles with heavy oxidation and may require multiple applications. The wax durability is average, lasting a few months at best. Skip this if your RV has severe oxidation or if you need long-lasting protection.
- Cleans light oxidation and stains while applying wax
- Safe for gel coat, fiberglass, and decals
- Easy application by hand or buffer
Pros: Good value for a cleaner wax combo; Works well on light to moderate oxidation
Cons: Not for heavy oxidation or deep scratches
7. Camco 40578 RV Wash and Wax: Best Budget
For budget-conscious RV owners, the Camco 40578 RV Wash and Wax offers a low-cost option. Our research shows it is a concentrated formula that dilutes to many gallons, making it economical. It cleans adequately for light dirt and leaves a slight wax shine. Owner feedback indicates it is easy to use and safe for all surfaces.
However, the wax protection is very light and does not last long, requiring frequent reapplication. It also struggles with heavy dirt or oxidation. Skip this if you need a heavy-duty cleaner or long-lasting protection without frequent waxing.
- Concentrated formula for multiple washes
- Safe for all RV surfaces including decals
- Leaves a protective wax coating
Pros: Very affordable per use when diluted; Easy to use, works with a bucket or foam gun
Cons: Wax protection is minimal and short-lived
Frequently Asked Questions
Can I use a car wash soap on my RV?
Yes, but it is best to use a product specifically formulated for RVs or boats. Car wash soaps may be too harsh for gel coat or may not provide the wax protection needed for RV exteriors. Look for pH balanced and biodegradable options.
How often should I wash my RV exterior?
It depends on storage and use. Generally, washing every 2-3 months is recommended to prevent dirt and oxidation buildup. If you travel frequently or park under trees, more frequent washing may be needed.
What is the best way to remove oxidation from an RV?
For light oxidation, a cleaner wax may suffice. For heavy oxidation, use a dedicated oxidation remover like Meguiar’s M5032 or 3M 09005, applied with a buffer. Always follow with a wax or sealant for protection.
Are waterless RV washes safe for decals?
Most waterless washes are safe for decals if used as directed. However, always test on a small inconspicuous area first. Avoid rubbing too hard, as dirt particles can scratch decals.
Should I wax my RV after washing?
Yes, waxing provides UV protection and makes future cleaning easier. If you use a wash and wax product, the wax layer is usually thinner. For maximum protection, apply a dedicated wax or sealant after washing.
Our Verdict
After comparing specs and owner feedback, our top pick for most RV owners is the Meguiar’s M5032 for its exceptional oxidation removal and restoration capabilities. For a convenient all-in-one, the Chemical Guys Lightning Fast is a solid runner up that saves time while providing decent protection.
