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 in 2024
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

Simple Green is an all-purpose, biodegradable, environmentally friendly siding cleaner. It was developed for multi-purpose contractor jobs, which explains its versatility. It can be used on many surfaces: Vinyl, wood, and metal. It removes grease and molds efficiently.
The biodegradable properties mean it’s entirely safe for outdoor and indoor use. No need to worry about your children or pets. The fragrance-free claim is a little misleading, however. The product smells clean and non-chemical, but it does have a noticeable cleaning product odor.
Worthy to note is that it’s a full product; 1 gallon of Simple Green for Vinyl Siding can produce about 64 mixed gallons. You should dilute it according to the type of surface you’re using it for and the type of stains.
Also, with its safer, more gentle approach to the cleaning solution, Simple Green does not attack mold and mildew like the more potent formulas above. This is a soft and more environmentally friendly approach to vinyl siding cleaning.

Tips on How To Clean Vinyl Siding:
Clean Vinyl Siding Without Scrubbing:
Many homeowners have been instructed that the only way to clean vinyl siding is with a pressure washer, which is no longer true.
Around twenty years ago, a few vinyl siding products that do not require scrubbing or a pressure washer came on the market.
The Three best “No Scrub/No Pressure Washer vinyl siding cleaners are RMR-86, Wet and Forget, and 30 Seconds Outdoor Cleaner. All of these are featured in our reviews (Above).
I have used all three siding cleaners in Michigan, Arizona, and Florida (Florida is the Worst by far for Mold), and they all work great!
I lean towards Wet and Forget, mixed with water, and applied with a garden sprayer to vinyl siding. Then, you sit back and watch mold and stains disappear over 30 days. No pressure washer and no dragging hoses to spray off the siding!
However, if you have a more immediate need to remove the vinyl siding mold and stains, RMR-86 removes stains almost immediately. You must take more precautions to protect your plant life, garden, or lawn – as RMR-86 is the most toxic to green life.
Is using a “Pressure Washer” to Clean Vinyl Siding Safe?
Whether or not it’s okay to use a pressure washer to clean vinyl siding depends on several factors:
- Low pressure is generally considered safe for vinyl siding. Aim for a pressure setting of around 1,500 psi or less.
- High pressure can damage the siding, causing cracks, warping, and even allowing water to seep behind the siding, potentially leading to mold and mildew growth.
- Use a wide fan nozzle to disperse the pressure and avoid concentrating it in one spot.
- Avoid using a turbo nozzle, which can be too powerful for vinyl siding.
- Hold the pressure washer nozzle at least 18 inches away from the siding. This will help prevent damage and ensure even cleaning.
- Use a cleaning solution specifically designed for vinyl siding. Avoid using harsh chemicals like bleach, which can damage the siding.
Condition of the siding:
- Newer vinyl siding is generally more resistant to damage from pressure washing. Older siding may be more brittle and susceptible to damage.
- If the siding is already cracked or damaged, it’s best to avoid using a pressure washer.
- Temperature: Avoid pressure washing in cold weather; the vinyl siding can become brittle and crack.
- Surroundings: Avoid damaging nearby plants or landscaping with the pressure washer.
Here are some general recommendations:
- A garden hose or a soft wash method may be sufficient for routine cleaning.
- Using a pressure washer, use the lowest pressure setting possible and keep the nozzle at least 18 inches from the siding.
- Always test the pressure washer in an inconspicuous area first to ensure it doesn’t damage the siding.
- If you are unsure about using a pressure washer, consulting with a professional is always best.

Ultimately, deciding whether to use a pressure washer to clean vinyl siding is up to you. However, by carefully considering the factors above and using the proper technique, you can help minimize the risk of damage to your siding.
How To Prevent Mold and Stains Returning to Vinyl Siding:
Preventing future mold growth:
- Improve drainage: Ensure water can drain away from the siding and not pool or stagnate. This can be done by grading the soil around the house so it slopes away from the foundation and regularly cleaning gutters and downspouts.
- Increase air circulation: Trim trees and bushes back so they do not shade the siding and prevent it from drying out. You can also install vents in the attic to improve air circulation.
- Regular cleaning: Clean the vinyl siding regularly with a garden hose and a mild cleaning solution. This will help to remove dirt and grime that can provide a food source for mold.
- Use a mold-resistant sealant: Once the siding is clean and dry, you can apply a mold-resistant sealant to help prevent future growth.
- Avoid harsh chemicals: Bleach and other harsh chemicals can damage vinyl siding and make it more susceptible to mold growth.
- Test any cleaning solutions or sealants in an inconspicuous area first.
- If you have a large area of mold or if you are unsure how to remove it, consult a professional.
Following these tips can help prevent mold from returning to your vinyl siding and keep your home looking its best.
Frequently Asked Questions (FAQ)
Q: What Is The Best House Siding Cleaner?
A: In our opinion and from our experience, the best house siding cleaner is the type of siding cleaner you 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 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 its product as “Safe for plants”; that product is a 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 five 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 is Wet and Forget, 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 each product’s coverage.
Q: Will Vinyl Siding Cleaner Damage Landscape?
A: If you have flowers or vegetation surrounding your house, thoroughly saturate it with water before you spray vinyl siding cleaner. Consider protecting them during the cleaning process by covering them.
Most chemical cleaners are potent products that can do damage to your plants.
Speaking of Natural Surroundings – Check out our How-To Guide – How to build an in-ground fire pit.
Q: Can Vinyl Siding Cleaner Damage The Siding?
A: Double-check that the vinyl cleaner you purchase is safe for 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 damaged the 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.
