Best Cleaner for Vinyl Siding – Buying Guide

There are many diverse reasons why people choose siding for their homes. Some want to improve their home’s aesthetics while others get them because of their low maintenance. No matter what the reason, there will come a time when you need to clean your siding which can collect lichen, mildew, mold, algae, grime, dirt, and dust over time.

Those that have already tried to clean siding know how hard these stains are to remove so finding the right vinyl siding cleaner is key to having the best curb appeal in the neighborhood.

The Importance of Getting a Great Vinyl Siding Cleaner

Vinyl Siding Cleaner

Even though vinyl siding is very low maintenance, it does require cleaning once a year. When washing your siding, you shouldn’t just any type of siding cleaner as you want to make sure your cleaner is able to get the grim and dirt off of your home. This is especially important if you siding hasn’t been cleaned well or at all over the years.

Then you will have to deal with a larger grim and dirt problem that can be very hard to clean off, plus you run the risk of health issues if you are breathing in the mold.

Having mold on or in your home can also attract bugs, particularly gnats which can give you a lot of trouble if they become infested in your home. They lay tons of eggs at once breeding very quickly and overwhelming your home before you know it.

You can avoid these issues by finding the right vinyl siding cleaner that is quick and strong while also being delicate enough so as not to cause damage to your landscaping or home.

Considerations When Choosing a Vinyl Siding Cleaner

Even though it may seem like a basic task to pick out vinyl siding cleaner, there are a few considerations to make before you decide on a cleaner.

Size of Your Home

Since there are many different size homes out there that have different width and length sidings, it is important to buy the right amount of vinyl siding cleaner for your project. This will keep you from making more trips to the store to get more or you will have to store it for next year’s cleaning./p>

Type of Siding

Depending on your taste, sidings can be made from plastic, wood, cement, metal, aluminum, or vinyl so you need to make sure the cleaner you are buying will work with the type of siding you have. You can also use many cleaners on patio furniture, garage doors, shutters, the roof, and interior areas like shower doors and tile.

Some siding cleaners are meant just for siding though and can be dangerous if used indoors, so make sure you are using your cleaner in the appropriate setting for your safety and to protect the surface you are cleaning.

At most, your vinyl siding cleaner should work on all the exterior surfaces of your home. Depending on the cleaner, you may be able to spray it and then just rinse while others may require you the use of a brush to loosen the mold and mildew. Try to find a cleaner that will clean the type of siding you have as efficiently as possible.

House Surroundings

You also need to consider everything that is surrounding your home like slabs, pavements, and brick as well as plants, grass, bushes, and flowers. The cleaner you choose will come in contact with the bushes, flowers, and grass, and it may cause them to wilt or die, especially if the cleaner is really concentrated.

Cleaners that are highly concentrated are good for getting rid of tougher stains but if your stains are not that bad you may want to choose a non-corrosive and eco-friendly cleaner that is gentler for the plants that surround your home. Usually, they consist of acid, lye, bleach, heavy metals and are phosphate free.

Types of Stains and Dirt

Depending on your geographical location, the stains on your siding may be different from someone else’s.

For those that live in a dry and sunny place, you may have more problems with dust and need a siding cleaner that works well on dust.

Others may live in an area that is very humid or rainy and has siding that is covered with dirt, lichen, mold, algae, and grim. Cleaners that work well on dust won’t be much help to you, so you will want to look for a cleaner that responds well to mold and algae. The best vinyl siding cleaners will be able to clean every possible stain off of your siding and may be your best choice.

Cost

Finding an affordable cleaner is one of the most important considerations in today’s economy. Make sure the cleaner you are choosing has the features you need instead of basing your choice on what is the cheapest so you don’t end up having to buy even more cleaner to finish the job.

Also, keep in mind the size of the container and make sure it will cover the square footage you have. Again, you don’t want to buy the cheapest cleaner only to find you don’t have enough.

How to Clean Siding

One of the most attractive and durable parts of your home, vinyl siding does need occasional maintenance so that it stays looking like new. Any exterior will stain over time with mildew, mold, and dirt causing your house’s exterior to look worn out and grimy. Just a little effort and time can give your home a brand-new look.
Before you begin to clean your vinyl siding, follow these steps to avoid large messes and possible health hazards.
Easy Way to Clean Your Siding

Safety First

Make sure to wear safety goggles, rubber gloves, comfortable clothing, and closed-toe shoes to protect your skin and eyes. A face mask is also a good idea so that you won’t breathe in fumes from the chemicals used in the cleaner. Also, remove any objects that might get in your way like toys and outdoor furniture.

You will also want to close all windows and doors to stop any water from getting inside the house. Also cover your landscaping, pot, and plants with tarps to keep them from being damaged by the cleaning products. It is also a good idea to cover, unplug, or turn off lights and electrical units.

No Direct Sunlight

It’s also important to choose the right day where there isn’t direct sunlight. A cloudy day will stop the sun from drying spots too fast and unevenly.

Cleaning Your Siding

Your first step is checking the condition of your windows and siding. Take a quick tour of your home’s exterior to make sure all of your siding is intact and you do not have any loose piece of vinyl. Also look for cracks in the siding where water can get it and find out on the long walls how the lengths overlap. Close all your windows and see if the glazing and caulking on the windows are in good condition so water doesn’t get in as you are working.

Also, water your garden beds that surround the edges of your home making sure to soak the soil well. This will help to dilute any chemicals in the cleaner that will reach these beds so that the plants don’t absorb them as easily.
Add the cleaner into your pressure washer following the directions on the container. Position the soap to the end of the wand on your pressure washing wand adjusting the pressure and angle so that it covers a wide area of the vinyl siding. Apply the soap to your siding while avoiding direct spray on the areas where vinyl lengths overlap which can force its way behind these vinyl panels and get into your insulation.

If the water does become trapped behind siding, it will not dry easily and can lead to water damage. This can also happen when spraying in corners so be aware of how water is affecting crevices where the siding meets.

It is also a good idea to wipe any of these areas clean with a dry towel to reduce the moisture in these areas.

Keeping the wand of the sprayer at a 45-degree angle will help to remove and lift dirt from beneath which is more effective than just blasting it straight on. Make sure to keep your eye on the soap level so you can refill it periodically as you run out.

When you are done with the siding cleaner, switch the tip of your sprayer to general use to get a stronger stream of water to remove the soap and the dirt loosened by the soap effectively from the surface of the siding.

Never blast the stream of water up or into corners as that can do more damage.

And, make sure to dry and clean corners to get rid of the extra moisture that may accumulate in these sensitive areas that tend to be more susceptible to water damage.
As you consider the type of vinyl siding cleaner that is best for your home, make sure to consider what features you need and what chemicals will be the best for everything that surrounds your home.

Once you know what type of cleaner you need, you should have no problem finding the right vinyl siding cleaner that will make your home look new again.

    I really need an inexpensive way to clean the oxidation off the siding of my house and you say the Krud Kutter could do that. I just don’t want to waste my money on something that doesn’t work because you also said it wasn’t very good compared to others.
