Things to Look Out for When Buying Vinyl Siding Cleaners

Now harmed with a review of 15 vinyl siding cleaners, the next important thing to go through is my list of crucial things to note while choosing one of these products.

Ingredients

Before you purchase any product, you should carefully check the ingredients list as the chemicals decide how the cleaner performs on your vinyl siding. You can look for the one made of water, hydrogen or alkyl sulfates, and more.

They are water-soluble and inorganic ingredients and don’t cause a bad reaction on the vinyl surface, as well as they can also eliminate some kinds of stains.

Besides must-have ingredients in a cleaner, you had better avoid using items produced from petroleum ethers such as acetone, benzene, THF, and organic solvents since they can discolor your vinyl material and reduce its flexibility and vitality.

Suppose you have challenges when making an effort to remove mold and mildew on the vinyl surface. In that case, you can use some products containing oxygenated bleach, ammonium chloride, and chlorine bleach to deal with them.

Keep in mind bleach can damage your plants around cleaning areas and your pressure washer; therefore, you can choose a bleach-based cleaner packaged in a spray bottle to reduce the cleaner that can be exposed to other things.

Type of Cleaner

There are 2 types of vinyl siding cleaners for you to choose from: concentrated and ready-to-use cleaners.

The concentrated cleaner requires you to dilute it with water according to a reasonable rate. Normally, each gallon of original cleaner will create 3-10 diluted liquid to serve your demands. This type is cost-efficiency for you; however, you need to prepare separate bottles to dilute it. It often comes in the large can.

Another choice is a ready-to-use cleaner or a pre-diluted one. You can buy the product packaged in a small spray bottle to serve you immediately when needed. It doesn’t take you any minutes to dilute it, but you have to spend more money getting one compared to the above type.

Packaging Type

Each type of cleaner will come in different packaging. The concentrated liquid usually is sold in large cans ranging from 0.5-5-gallon bottles, but you can buy the smaller ones to meet your needs. You can use the cap to measure 1 fluid oz or other amounts to help you dilute the right rate.
The ready-to-use cleaner is contained in a spray bottle or comes with a spraying adapter to install a pressure washer hose. These products are easy to find, but they have less and cost more than the others.

Eco-Friendly

When you clean outside, you need to pay extra attention to the environment around cleaning areas since it is a place that the liquid ends up. If you want to protect pets and plants from harsh cleaners, you can choose a vinyl siding cleaner with some words such as non-toxic, EPA safer choice, and biodegradable on its packaging.

All labels will ensure the cleaner doesn’t ruin the environment. This product is also safe for you, your family members, your pets, and your neighbors since the fumes from eco-friendly are gentle and safe.

Smell

The smell is a crucial factor you should care about when finding a vinyl siding cleaner. You had better choose non-smell or gentle smell products to use, especially the cleaner works with pressure washing hose since it can create fumes.

How To Apply A Vinyl Siding Cleaner

Depending on which type of vinyl siding cleaner you select, you can choose different ways to apply your product. The popular methods use an integrated applicator or spraying the cleaner on vinyl with the pressure washer with a bucket and a soft-bristled brush to rub it when needed. Here are the ways to apply the cleanser on the vinyl surface.

An important note for you is that you have to rinse your vinyl siding with clean water to eliminate residue on it despite using any method.

Pressure Washing

Pressure washing is the quickest and easiest to apply cleaner. However, keep in mind choosing the suitable cleaner can work productively with a pressure washer since not all cleaners can make suds when it is blasted at high pressure, and the bleach-based cleaners will damage the hose.

Remember not to climb on the ladder when using a pressure washer since you can fall when facing strong pressure. You should use the extension want to help you reach the high places.

Built-in Applicator

You can opt for the cleaner designed with a bottle with a hose-end and spraying head if you want to apply the cleanser with an integrated applicator. To use this way, you have to connect the spraying head to your existing hose, and the other connects to a spigot in your garden and starts running.

The cleaner will release the water to create diluted liquid for the cleaning task, and this method doesn’t require you to load any fluid into an added device.

Manual Application

When you apply cleaner according to this, you should choose a vinyl siding cleaner that comes in a screw-in bottle to help you store it easily after use. You can pour the liquid into a bucket, then dip the brush and rub your vinyl siding.

Don’t forget most cleaners are designed for a pressure washer that can be manually applied; therefore, you don’t need to feel confused when reading their labels.

FAQs

Here are a few popular questions that arise when it comes to the subject of finding the most suitable vinyl siding cleaner based on each person’s tastes and needs for it.

My Top Pick

Almost expectedly, I chose all-rounder RMR-86 Instant Mold Stain & Mildew Stain Remover is my top pick. There is no going wrong with this product.

It is safe for the environment, poses no harm to human health, and thoroughly cleans fungal growths from vinyl siding and a wide range of surfaces. Buy the RMR-86, and you will not regret it!
