- Designed for RV Life – Tailored specifically for RVs, campers, motorhomes, and trailers, this cleaner meets the needs of those who live the RV lifestyle and need efficient, hassle-free solutions.
Cons:
- Limited Availability – Although Walex offers a high-quality cleaner, finding it in local stores can sometimes be challenging, which might make it less accessible for last-minute cleaning needs.
- Not Ideal for Heavy Roof Damage – While this cleaner is great for regular maintenance and dirt removal, it may not be powerful enough to handle extremely worn or cracked roofs. For severe damage, a more specialized product might be needed.
- Requires Application of Additional Products for Heavy Duty Cleaning – While the cleaner works great for regular maintenance, for particularly tough stains, you may need to apply it more than once or combine it with other products to achieve the best results.
- Scent Might Be Strong for Sensitive Users – Some users may find the scent of the cleaner overpowering, especially during extended application periods. If you are sensitive to scents, you might want to ensure proper ventilation while using it.

- Essential for RV Maintenance – This cleanser is an indispensable tool for ensuring your RV roof is in top shape, especially before applying protective coatings or other maintenance treatments. Regular use helps keep your RV roof clean and well-prepared for ongoing care.
- Versatile and Safe for All Roof Types – The cleaner is safe for use on all RV roof materials, making it a versatile solution for different types of RVs. You won’t have to worry about damaging your roof’s material or finish with this product, as it’s designed for gentle yet effective cleaning.

Cons:
- Requires Scrubbing – Although it’s easy to apply, the need for scrubbing with a medium-bristle brush may not be ideal for some users. Those looking for a completely hands-off cleaning experience might find this a bit more labor-intensive.
- Not Ideal for Heavy Stains – While it works well for regular cleaning, tougher, more stubborn stains might require additional treatments or more intensive cleaning efforts. It may not be powerful enough for deeply ingrained dirt or for roofs that haven't been maintained in a while.
- Scent Could Be Off-Putting – The scent of the cleaner might not be pleasant for everyone, especially when used in enclosed spaces or without ventilation. It’s not overpowering, but it could be a downside for users who are sensitive to smells.
- Only a Refill, No Sprayer Included – The product is a refill, meaning you’ll need to have a separate sprayer for application. For new users, this might be an inconvenience as it’s not a complete kit. You’ll need to purchase the sprayer separately if you don’t already have one.
- Can Leave Residue If Not Rinsed Properly – If the cleaner isn’t rinsed off thoroughly, it could leave some residue behind. This might lead to streaking or even damage to the roof’s finish if left unchecked, so ensuring the cleaning process is followed carefully is important.

Pros:
- All-in-One Cleaning Solution – The THETFORD Premium RV Rubber Roof Cleaner & Conditioner offers a convenient, single-step cleaning solution that not only removes dirt and grime but also conditions and protects your RV roof.

It’s non-toxic, non-flammable, and 100% biodegradable, making it a safer choice for both the environment and you. This feature is especially great for users who prioritize eco-friendly products without compromising on performance.
- UV Protection – With the added benefit of a UV blocker, this cleaner helps prevent the sun from degrading your RV roof over time.

Cons:
- Requires Some Effort for Stubborn Stains – While the cleaner is generally effective, tougher stains or long-term buildup might require a bit of scrubbing or multiple applications to fully remove. This could be a downside for users who are expecting a completely hands-off cleaning process.
- Smell Might Be Strong for Some Users – Though the cleaner is non-toxic and biodegradable, some users may find the scent a bit overpowering during application. While it's not necessarily unpleasant, it’s still something to keep in mind if you’re sensitive to fragrances.
- May Not Work on Every Roof Type – The cleaner is designed to work on most roofing materials, but some specialized or delicate roof materials may not respond as well. If you’re using a non-standard material for your RV roof, it’s worth testing the cleaner on a small area first to ensure compatibility.
- No Sprayer Included – While the product is effective, it comes as a liquid that requires manual application with a sprayer or brush. If you don’t already have the proper tools, this could be an inconvenience, as they’re not included with the cleaner.
- Price Point – Compared to other RV roof cleaners on the market, THETFORD’s Premium Cleaner & Conditioner is on the higher end in terms of price.

If you’re looking for a cleaner that can handle the elements, this one’s up for the task.
- Prevents Mold and Mildew – The cleaner goes beyond just cosmetic care. It actively helps prevent the growth of mold, mildew, and fungus on your RV roof, which is a real bonus for those who camp in humid or wet conditions. This feature not only improves the longevity of your roof but also ensures that your RV remains in pristine condition.
- UV Protection – With UV-blocking properties, this cleaner helps protect your rubber roof from the sun’s harsh rays, which can cause the roof to degrade and crack over time.

- Generous Size – The 128 oz. bottle gives you plenty of product for multiple applications, making it a great option for regular RV maintenance. It’s especially useful for those who prefer bulk purchases for longer-term use or for larger RVs that require frequent roof care.
Cons:
- May Require Multiple Applications for Heavy Stains – While the cleaner is effective, some particularly stubborn stains or heavy oxidation might require more than one application. For users with significant buildup or neglected roofs, this might result in extra effort to achieve the desired results.
- Can Be Overwhelming for New Users – The dual-action nature of this cleaner may be confusing to new users, especially those unfamiliar with roof care products. There’s a slight learning curve to ensuring you apply it correctly and achieve the best results.
- Not the Best for Other Surfaces – Although this product is perfect for rubber roofs, it may not be suitable for other materials. If you’re hoping to use it on your RV's sidewalls or other exterior surfaces, it may not deliver the same level of effectiveness.
- Strong Scent During Application – Some users may find the scent of the cleaner a bit overpowering, especially during the application process. While not unbearable, it’s something to keep in mind, especially if you’re working in enclosed spaces or areas with limited ventilation.
- Relatively High Price – Compared to other roof cleaners, B.E.S.T. 55128 is on the higher end of the price spectrum. While the quality justifies the cost, some users may find it a bit steep for regular maintenance, especially for those who have larger RVs or frequent roof cleaning needs.
303 30239 Rubber Roof Cleaner
Pros:
- Biodegradable & Non-Abrasive Formula – The 303 Rubber Roof Cleaner is an eco-friendly solution for cleaning your RV's roof. It’s biodegradable, meaning it won't harm the environment, and its non-abrasive formula ensures that your roof material remains intact and undamaged. This makes it an excellent choice for those looking for a cleaner that won’t wear down the surface over time.
- Safe for Solar Panels and Roof Seals – One standout feature of this cleaner is its ability to clean without damaging solar panels or rubber seals. Many roof cleaners can be harsh, but 303 ensures that delicate components of your RV, like solar panels and seals, stay protected. This is a major plus for RV owners who want a cleaner that can handle the entire roof without worrying about damage.
- Perfect for Pre-Treatment – Before applying 303 Aerospace Protectant, this cleaner works wonders as a pre-treatment.

- Effective Dirt Removal – This cleaner excels at dissolving dirt and grime, particularly on rubber roofs, making it easier to keep your RV in pristine condition. Whether it's road film, environmental debris, or other common roof dirt, this cleaner gets the job done quickly and efficiently.
Cons:
- Might Require Multiple Applications for Heavy Build-Up – While the cleaner works well for regular maintenance, stubborn stains or heavy buildup may need more than one application. If your roof hasn't been cleaned in a while, you might find that you need to put in some extra effort to fully remove all dirt and grime.
- No Immediate Shine or Finish – Although it cleans effectively, this product doesn't leave behind the glossy, shiny finish some RV owners might expect after cleaning. For those looking for a cleaner that adds an extra layer of shine, you might need to follow up with a separate finishing product.
- Requires Proper Rinsing – Like many cleaners, 303 Rubber Roof Cleaner needs to be thoroughly rinsed off after application. If not rinsed well enough, residue might remain, which could affect the roof's performance and the application of any subsequent protectant.
- Scent May Not Be for Everyone – The scent of this cleaner is relatively neutral, but some users may find it a bit strong during application. This isn’t a huge issue, but if you’re sensitive to smells, it’s worth considering proper ventilation during use.
- Not a One-Step Solution for Severe Roof Damage – While the cleaner is great for regular maintenance and dirt removal, it may not be powerful enough to deal with more significant issues like deep oxidation or severe roof damage. For such situations, additional treatment or a more specialized product might be necessary.
