If you’re looking for the Best Vinyl Siding Cleaner for your home, you’re in the right place. Today, we share the results from our research and list the top-rated best vinyl siding cleaners you can buy – and, more importantly, which vinyl cleaners work best!
We’ve all seen the dreaded “green monster” of mold or mildew on the neighbor’s siding – or, heaven forbid – your vinyl siding 🙂
Never fear; while each of these vinyl siding cleaners in our Buying Guide works slightly differently, each one of these “cleaners for vinyl siding” makes it easy to remove mold, mildew, and dirt from vinyl siding, and with most of them, there is no need to use a pressure washer.
“RMR-86″ Vinyl siding cleaner, for instance, is pre-mixed and ready to go, whereas a product like “Wet & Forget” is mixed with five parts water to 1 part concentrate.
If you’re witnessing any of the above vinyl stain conditions, your house has probably gone too long between baths. This is the “Before & After”– following the application of vinyl siding cleaner.
Years ago, the only solution for cleaning vinyl siding – would be to rent or own a Pressure Washer or scrub the siding with a soft brush and garden hose to remove mold. Today, however, there is a much quicker, easier, and less expensive way to clean vinyl siding effectively.
This year get your hands on one of the Best Siding Cleaner products below. These products are specially formulated to guard against existing and future mold, and you will be amazed at how easy they are to use.
The 8 Best Vinyl Siding Cleaners
The RMR-86 Mold Removal product is advertised as a miracle cleaner, and we think it lives up to that claim. RMR-86 cleans stubborn mold and mildew within 15 seconds or less – and does so almost effortlessly.
You don’t need to scrub or brush; you fill a bug sprayer, spray the stained area, wait for 15 seconds, and watch the transformation begin. I have used this product repeatedly and “always” with great success.
The RMR-86 product linked here is for a 2-gallon container (128 ounces) – that is applied full strength (not concentrate), and per manufacturer, this amount of mold killer – will cover 500 sq. ft of material.
Another thing we love about RMR-86 is its versatility. You can use it on any surface: wood, vinyl, concrete, fiberglass, and siding.
Interestingly, it can penetrate porous surfaces quite well without changing their color. It’s genuinely one of the best Vinyl siding cleaners on the market.

RMR-86 – Editor’s Pick – Best Vinyl Siding Cleaner
If you don’t feel comfortable using a bleach-based cleaner, we’ve covered you. Wet & Forget is non-acidic and non-caustic; you can use it safely on any surface without worrying as much about harming animals or plants.
The Wet & Forget aim is to make your life easier and your cleaning smarter with a user-friendly – “spray and walk away” product. Rain will eventually remove any residue over time. Just like RMR-86, there is no need for abrasive scrubbing.
Of course, if you live in an arid climate – like the southwest – you could go weeks without rain, so Wet & Forget may not be your first choice 🙂
To use Wet & Forget, you will need a typical garden sprayer and water to mix the recommended five parts water with 1 part Wet and Forget concentrate. Spray liberally on the material you want to remove mold on and walk away. Literally.
The “trade-off” from using RMR-86 instead is that Wet and Forget is a more gradual cleaning agent, and while you should see results within a week, Wet & Forget requires 1-3 months to remove visible mold and stains entirely.
Wet & Forget is still considered one of the best vinyl siding cleaners on the market, especially if you have time to allow the product to do its job and want the simplest application method.
One precaution to keep in mind is the weather conditions. If the product hasn’t thoroughly dried, rain would rinse it before it activates. Also, windblown debris may lead to an unsightly outcome. Just pick a clear day, and you’re good to go.
- Garden/Pump Sprayer – For Wet and Forget – Mix five parts water to 1 part Cleaning solution and apply to vinyl siding.
- 2,000 Sq. Feet per 5 Gallon Mixed Product

Frequently Asked Questions (FAQ) Vinyl Siding Cleaner:
Q: What Is The Best House Siding Cleaner?
A: In our opinion and from our own experience, the best house siding cleaner is the type of siding cleaner that you simply spray on and walk away.
Products such as Wet & Forget house and siding cleaner are among the best examples; a concentrate ready to mix with water, apply with a pressure sprayer, and avoid using a pressure washer entirely.
For plain dirty siding (without mold or mildew attached), a good DIY Siding Cleaner can be made by mixing 30% vinegar with 70% water or Dawn Dishwashing liquid with Hot water.
However, in our experience, both DIY methods work well for general cleaning but not mold or mildew removal.
Q: Which Siding Cleaner is Safe For Plants?
A: From our research, only One Vinyl siding cleaner describes their product as “Safe for Plants”, that product is Simple Green “biodegradable” cleaning solution (see review above).
However, as mentioned in our article, Simple Green is considered a multi-purpose cleaner – not specifically made as the ultimate vinyl siding cleaner. It isn’t, but it is, however, considered to be an environmentally safe product.
In the end, using a vinyl siding cleaner to be safe around plants or other vegetation, hose down the plants with a wide-angle nozzle from a garden hose, saturating it just before applying the house cleaner.
When finished applying the siding cleaner, spray the vegetation again – rinsing thoroughly, and you should be all set. This has been my approach for over 5 years, and I have had no damage to plants due to vinyl siding cleaner applications.
Q: Which Vinyl Siding Cleaner Brand Should I Buy?
A: Our favorite Vinyl Siding cleaner to buy, is Wet and Forget, which is formulated to spray on the vinyl siding and walk away, with 1 – 3 months to achieve full results. (this is the one I use most often -because it works amazing – and the mold doesn’t return).
Other products we’ve reviewed, such as “30-Seconds Cleaner” require hosing the siding off with water about 10-15 minutes after applying the vinyl siding cleaner.
Some products like RMR-86 cost more due to the full-strength application and more limited coverage of your house. However, they are more powerful stain and mold removers, (vs. pressure washers) and work instantly (within 15 seconds).
Whichever type of siding cleaner you choose, these specially formulated mold and mildew removers do fantastic work, and in a short time, your Vinyl Siding should look as good as new.
Q: How Much Vinyl Siding Cleaner Do I Need?
A: Each Brand’s Formula determines How Much Siding Cleaner You Need:
The size of your home determines the “amount” of vinyl siding cleaner you will purchase, and to determine how much vinyl siding cleaner you need, You need to estimate your square footage correctly.
Step 1: From the ground, eyeball the width and height of each side of your house.
Step 2: Next, multiply width x height, and add all four sides to your total square footage needed to determine the amount of vinyl siding you have. Example: 30’ wide x 20’ ft. high = 600 sq. ft. x 4 sides = 2,400 sq. ft. total coverage required.
Step 3: compare the recommended coverage for the above vinyl cleaning products, and get the best vinyl siding cleaner based on your needs. Some are concentrates; some are pre-mixed; please refer to our reviews for the coverage of each product.

Q: Can Vinyl Siding Cleaner Damage The Siding?
A: Double-check that the vinyl cleaner you purchase is safe for use on Vinyl products and will not bleach or damage your siding.
According to the manufacturers in our Reviews, None of the vinyl siding cleaners in our review damage vinyl siding.
Q: How Can I Keep Mold & Mildew Off Vinyl Siding?
A: The best way to keep mold and mildew from returning to vinyl siding, is to attack the mold before it gets out of control. The best time is late spring-early summer when you see the mold starting to grow.
Your house’s location determines the dirt you’ll likely encounter. Very Damp areas and North facing elevations are more likely to accumulate mold and algae on vinyl siding, while dry or windy climates may produce a more significant dirt buildup.
One of the most common reasons for vinyl siding stains is the result of tree branches or large bushes located within a few feet or even touching the vinyl siding. Another issue is allowing grass to grow against the foundation of your house without using landscape beds.
To avoid that problem, trim back any natural vegetation at least 4-5 feet away from your siding – to prevent future staining.
