What Is a Vinyl Siding Cleaner?
A vinyl siding cleaner is a liquid cleaning product designed to work on vinyl siding, as well as other materials. Different products require different techniques. Some are applicable via a power washer, while others can just be sprayed on.
A vinyl siding cleaner can remove dirt, debris, stains, mold, mildew and generally freshen up the appearance of your home.
How to Choose the Best Vinyl Siding Cleaner
To get the best vinyl siding cleaner for your home, here are some important details to note when shopping.
Ingredients
Don’t use products with organic solvents such as acetone, undiluted bleach, liquid grease remover or furniture cleaners. This can damage the vinyl (1).
Also, look out for assurance that the product won’t damage or kill grass or plants. If you have greenery around, you don’t want your vinyl siding cleaner to ruin them.
Environmental Impact
Look for products with the EPA Safer Choice label — this means it’s a safer choice for you and the environment (2). Noting that a product is biodegradable and labeled as non-toxic are also key qualities to look out for.
Formula
Vinyl siding cleaners are either formulated as ready-to-use or concentrated. Concentrated formulas are more economical since they go a longer way, but they need to be diluted. However, if using in a pressure washer, the machine will do it for you.
Ready-to-use formulas are convenient, but won’t last as long.
Application
You can use your cleaner in a pressure washer — but there are two other application options. Built-in and manual.
Built-in means the product has a spray head or hose end. So you can spray it all over your vinyl siding. Or you can connect it to your outside tap and use it that way, mess-free.
Manual means that you’ll need to pour the solution into a basin or bucket. Then apply it manually with a sponge, brush or cloth. If you have a cleaner that works with a pressure washer, you will likely also have the option of manual application.
Smell
Scent isn’t a huge priority for vinyl siding cleaners since you’re going to be applying it outside anyway. However, some products do have a fragrance so you can opt for those if you enjoy scented cleaners.
Type of Siding
While all of our recommendations work on vinyl siding, some are compatible with other siding types. If you have multiple materials on your house or are offering to help out a neighbor, check out these details. Many cleaners will work on a multitude of surfaces.
Cost
Vinyl siding cleaners come in a range of prices to fit most budgets. Many people opt for vinyl siding because the maintenance costs are low.
Purpose
Different siding cleaners have different purposes.
Some are formulated specifically for removing stains, while others attack mold and mildew. Others are meant to freshen and brighten, while some just do general cleaning. Depending on your needs, note the purpose of the best vinyl siding cleaners so you can find the right one for you.
The Best Vinyl Siding Cleaner of 2021
We’ve spent hours reading product reviews, expert advice as well as applying our own insight. With this information, we have a list of the seven best vinyl siding cleaners to get your house sparkling fresh!
1. Charlie's Soap Indoor & Outdoor Surface Cleaner
If you like to get all-in-one products to save a bit of money and space in the cupboards, you’re not alone!
Our recommendation for the best multipurpose vinyl siding cleaner is the Charlie’s Soap indoor and outdoor surface cleaner.
This product cleans pretty much everything. If you have something that needs to be freshened up or totally restored — choose this product.
Why We Love It
Multipurpose
The tag line on this product is that it “cleans everything from false teeth to diesel engines”. So when we say it’s multipurpose — it’s multipurpose. It can be used on any indoor or outdoor surfaces, including decks, cars, boards, bikes, driveways, siding, walls, engines, furniture, grills and more. Of course, this includes your vinyl siding.
Safe
Charlie’s Soap is an eco-friendly company and this product is no different. It’s non-toxic and biodegradable. It contains no abrasives, lye, phosphates, bleach, dyes, perfume, or fillers.
You don’t even need to wear gloves. It’s made with naturally derived ingredients, proven strong enough to clean your home, but gentle enough to treat the environment kindly.
Treats Grease and Grime
This product was originally intended to cut grease and grime. While it can do more than that now, it still wonderfully cuts through grease and grime. It gently releases these stains inside and outside the home, leaving you with clean results.
Keep In Mind
Requires Scrubbing and Rinsing
Charlie’s Soap indoor and outdoor cleaner isn’t the easiest to apply and remove. First, it requires scrubbing. Not a lot, but do keep this in mind. Secondly, it can be quite difficult to rinse it away thoroughly. Some customers note there is a residue left behind and it needs a few rinses.
Additional Specs
| Formula | Concentrated, but can also use at full strength |
| Application | Apply with a pressure washer, mop, cloth, or spray bottle |
| Type of Siding | Any |
| Purpose | Cleans, eliminates grease and grime |
| Size | One gallon |
2. Zep House and Siding Pressure Wash Cleaner
On a budget but still need to get that vinyl siding spick and span? Zep House and Siding Pressure Wash Cleaner offers two bottles for less than $30.
Plus, the formula is concentrated. So in total, it makes up to 20 gallons of siding cleaner which should last a seriously long time.
It is designed to be used in a pressure washer, but of course, you can also use it manually.
Why We Love It
For Multiple Surfaces
This cleaner can be used on vinyl, of course. But it’s also good for aluminum and wood siding. Finally, it can also be used for cleaning gutters, brick, cement and hard coat stucco. Do not use this on deteriorated surfaces.
Revives and Removes Stains
The Zep House cleaner revives your siding so that you can have a super clean exterior once again. It also removes stains of dirt and mildew. So your house can go from looking dull and dingy to looking bright and clean.
Safe for Plants
The Zep House cleaner will not cause damage to your plants. Of course, make sure to dilute it first if not using it in a pressure washer.
The only thing to note about this product is that it might cause eye irritation, so wear goggles for extra safety (3). Also — keep away from children and pets.
Keep In Mind
Timing Is Important
We recommend not using this product on a sunny day. If it dries before you’ve rinsed it, you can end up with streaky lines on your siding which are difficult to remove. The sun can flash dry the product.
Additional Specs
| Formula | Concentrated — up to 20 gallons |
| Application | Manual or pressure washer |
| Type of Siding | Vinyl, wood, aluminum, brick, hard coat stucco, cement |
| Purpose | Removes dirt and mildew, and brightens |

The Simple Green Pro HD is a professional grade product, so you can use it at home or at your residential building, too.

Keep In Mind

Contains Bleach
Note that this product contains bleach. So if you want something more eco-friendly, choose a different option. Because it contains bleach, wear protective gloves, eyewear and old clothes.

FAQs
Is It Okay to Power Wash Vinyl Siding?
Yes, but be careful. Vinyl siding isn’t as durable as other materials such as metal and brick. Test in a small area of your vinyl siding on a low pressure first to check if the siding responds well.
Is Bleach Bad for Vinyl Siding?
If you use the bleach properly, diluted and rinse it away, it shouldn’t damage your vinyl siding (5). The Mold Armor FG503 E-Z House Wash we recommend contains bleach. But because it is diluted, it’s not going to damage your siding.
How Do You Clean Vinyl Siding Without Scrubbing?
First, you can use the pressure washer. The pressure of the liquid acts as a scrubber to remove dirt from the siding.
But if you choose a good quality formula and let it soak on the vinyl for a decent length of time, you shouldn’t need to do much scrubbing. Simply rinsing it off afterward with a hose or cloth should easily lift and remove the dirt.
How Often Should You Clean Vinyl Siding?
Roughly once a year. However, if you live in a humid or dusty place, it might need to be more often to keep mildew and dirt under control.
Definitely check the vinyl siding every four months to see if it could benefit from a light clean. Prepare for a deeper clean once a year, but if the vinyl looks pretty neat — wait until next year!
Can I Make My Own Vinyl Siding Cleaner Solution?
You definitely can. If you’d like to be eco-friendly and save money, then this is a great option.
One recipe we recommend is this:
- Mix 3.5 cups of distilled white vinegar and ½ gallon of water in a bucket.
- Use a long-handled scrub brush to apply the solution to the siding. Start at the top and work your way down.
- Work in small sections, rinsing the vinegar solution off before its dry.
- Repeat.
How to Use Vinyl Siding Cleaners Safely
- Work from the top down: There are narrow gaps between each piece of vinyl siding. If you go from the bottom up, you risk getting water in those gaps which can cause dampness underneath the siding. Also, the dirty water drips down, so if you clean the bottom first, the dirt from the top will trickle down at the end.
- Shut off the power: Before you start cleaning, shut off the power to the exterior of your home. Water and electricity do not mix!
- Cover lighting and outlets: Use a plastic bag or protective cover to shield outside lights and outlets so that they don’t get wet.
- Use low pressure: If using a pressure washer, use low pressure so that you don’t damage the vinyl.
- Wear gloves and glasses: This is an important tip especially if you’re using a pressure washer since the cleaning solution can spray back at you. It’s best to keep your skin and eyes covered since lots of solutions can irritate your skin and eyes.
