If you’ve recently purchased a house and want to make it look as best as possible, we can help. Vinyl siding is one of the best products for exterior home décor because it’s durable, easy to install, and comes in a vast range of colors.

Unlike other types of siding, it doesn’t need repainting; it doesn’t rot, crack or chip either! The best part about vinyl siding is that it gets dirty or moldy/mildewy – all you have to do is clean it with your pressure washer!

What Is a Vinyl Siding Cleaner?

Vinyl siding cleaners are products that help you safely remove dirt, mold, and mildew from your vinyl siding. They’re best used in conjunction with a pressure washer because they loosen up the grime so it can be rinsed away more efficiently by high-pressure water.

How to Choose the Best Vinyl Siding Cleaner

Ingredients – Look for a vinyl siding cleaner that’s as natural as possible. It should only contain all-natural materials and no harsh chemicals or toxins.

Environmental Impact – Vinyl sider cleaners can sometimes harm the environment. So look out for products with minimal environmental impact – especially if you’ve got an eco-conscious buyer on your hands.

Formula – It should be non-foaming and work best with a pressure washer.

Application – You can apply most vinyl siding cleaners via spray or brush. Some are even designed to foam up, so they cling to the surface better for easier rinsing.

Type of Siding – Make sure the cleaner is suitable for your siding. Some cleaners can damage certain types of vinyl, so best to check with the brand before you buy!

Cost – You can find vinyl siding cleaners for as little as $15 or upwards of hundreds. Still, it depends on what ingredients and how much is included in the formula. It’s best to look for a cleaner that best suits your budget.

Purpose – Some cleaners are explicitly designed to remove mold and mildew. Others can be used as general-purpose cleaners, too – so read the label carefully before you buy!

Smell-Vinyl siding cleaners aren’t too concerned with the scent of their products since they’ll be applying it outside anyhow. On the other hand, some products have a fragrance, so you may choose one if you like fragrant cleaners.

After Using Your Pressure Washer Checklist & Storage Tips for Vinyl Siding Cleaners

Once you’re done, make sure to wipe down the cleaner from your siding and store it properly until next time! If there are any stains left behind, best to use a simple household solution of vinegar and water.

What Is the Best Way to Clean Vinyl Siding Safely?

Turn off the electricity: Turn off the power to your home’s exterior before you begin. Electricity and water don’t go together!

Start from the top down: There are tiny gaps between each piece of vinyl siding. If you work your way from the bottom up, you risk water getting inside those gaps, resulting in dampness beneath the siding. Another disadvantage is that the dirty water trickles down, so the dirt from the top will flow down if you clean the bottom first.

Protect lighting and outlets: If you’re using lights or outlets outside, cover them with a plastic bag or a protective lid to prevent them from getting wet.

Wear safety glasses and gloves: This is a crucial hint, especially if you’re using a pressure washer, since the cleaning solution may shoot back at you. Also, it’s best to keep your skin and eyes covered because many chemicals can irritate your skin and eyes.

Use a low-pressure setting: If you’re using a pressure washer, use a low setting to minimize the risk of vinyl damage.

Read Instructions: Always read your product’s manufacturer’s instructions for further information.

Why Is It Necessary to Clean Your Vinyl Siding?

Vinyl siding is a popular choice for homeowners who want to give their house a cosmetic upgrade without investing in significant construction work. Because it’s accessible to clean and low-maintenance, vinyl siding can significantly improve the look of your house.

It’s essential to keep your home’s exterior looking its best. Because it helps your house look great and dirty siding can wear away the finish over time. 

Below are some of the main reasons you should make cleaning your vinyl siding an essential part of your spring or fall maintenance routine.

Warranty Protection: Cleaning Your Siding protects Its Warranty Washing dirt, grime, pollen, and other debris from vinyl siding helps prevent damage that can void the warranty.

Shiny Look: Removing Stains Helps Your Unsightly Siding dirt, grime, and stains can make your house look run down. But removing them helps restore the original beauty of your siding. 

Increase Resale Value: Removing Spots Makes Your Home More Resale-able, Even if you aren’t planning on selling your house anytime soon. Cleaning spots off of your vinyl siding can help make it more marketable in the future if you decide to put it up for sale. Stains, mold, or dirt can make your home seem less appealing to potential buyers.

Tax Credit: Today’s vinyl siding is better than ever before because it comes with features that protect the house from water damage and help it retain heat in cooler months. You may even be able to get a tax credit for having vinyl siding installed on your home. 

However, you can take these perks away if you don’t maintain them properly. With just a little effort and regular cleaning, however, you can keep your siding looking new for years to come.

Increase Durability: Keeping grass and shrubs away from your siding is vital because overgrown plants can trap moisture between the vinyl and the house, causing damage. 

Use a broom or a hand-held outdoor vacuum cleaner with a soft brush attachment to suck up any fallen leaves or other debris from the surface of the siding. If you get regular spring cleanings of your exterior, all the debris will already be gone, making your job easier.

How do I best store my vinyl siding cleaners?

Make sure that they’re stored out of the reach of children and pets. If they’re stored in a metal container, best to keep them away from direct sunlight, too. It can oxidize the chemicals inside over time, making them less effective!

What Pressure Washer Should I Use?

You can use any pressure washer for best results, but it’s best to look out for one that has a high PSI (pounds per square inch) rating. You should aim for at least 2000-3000 PSI. Otherwise, you might not see desired results.

Do Vinyl Siding Cleaners Expire?

Nope! Vinyl siding cleaners are best stored at room temperature and won’t expire either.

Is it Safe to Use Bleach on My Siding?

Yes, bleach is safe for vinyl siding but best used in small quantities mixed with dish soap (or another suitable cleaning agent). Mix the solution in a bucket and scrub your siding with a medium bristled brush.

How often should I wash my vinyl siding?

It depends on how dirty it gets from the elements. If your house is exposed to a lot of dirt and grime, it’s best to clean it every year or so, especially if you notice some mold building up between the grooves.

Should I use a high or low-pressure washer to clean my vinyl siding?

Vinyl siding is resilient and durable, but it isn’t indestructible. With a powerful force like water from your pressure washer, you can damage the surface of vinyl panels, causing delamination or cracking in some cases. 

In addition, it will lead to leaks around seams where rainwater gets into microscopic gaps between pieces due to tension caused by wind loading them down against each other and distortion. 

To avoid damaging anything on my property, I always ensure that 1800 PSI (or higher) isn’t used. 

What is the best way to clean vinyl siding without scrubbing?

The first option is to use a pressure washer—the force of the liquid acts as a cleaner on the siding, removing dirt from it.

If you use a high-quality formula and soak the vinyl for a reasonable amount of time, you should not need to do much scrubbing. After that, clean it off with a hose or cloth.
