How to Clean Vinyl Siding with a Pressure Washer?

Best Vinyl Siding Cleaner For Pressure WasherPressure washing vinyl siding can be easily done by preparing the area, connecting the pressure washer to a water supply and to a power source, rinsing the area with plain water, applying pressure washer vinyl detergent, letting the detergent soak in, and rinsing it off at the end. The steps needed to clean vinyl siding with a pressure washer are discussed in detail below.

Step 1. Prepare the area.

Before pressure washing vinyl siding, carefully inspect the surfaces that need to be cleaned. Make sure to repair any flawed parts before starting the job to avoid further damage. Remove any tough to clean dirt using a brush before beginning the pressure washing procedure.

Remove all objects in close proximity to avoid hose entanglement. Make sure pets and children are kept away during the power washing procedure.

Step 2. Connect the pressure washer to a water source.

Attach a garden hose to a water supply and run water through it for less than a minute to remove debris and air. Turn off the water supply, and connect the hose to the water inlet fitting situated on the pressure washer.

Step 3. Connect the pressure washer to a power source or check the fuel.

If the unit used is an electric pressure washer, inspect the power cord and make sure that it is not damaged. Test the GFCI system as instructed by the pressure washer’s manufacturer in the user manual. Plug the power cord into a compatible electrical outlet.

If the machine used is a gas-powered pressure washer, check the engine fuel and oil levels, and inspect the oil levels of the power washer pump. In case these levels are low, add the necessary lubricant and refill the fuel tank with clean gas.

Step 4. Rinse the vinyl siding with lain water.

Vinyl siding is a strong material but it is prone to bending and scratching. The pressure washing procedure of this material needs to be done correctly. Attach a green or white pressure washer nozzle to the wand. Turn on the pressure washer and keep a distance of 8 to 24 feet away from the surface. Set the pressure rate to about 2000-2800PSI. Starting from the bottom, or the top makes no difference at this point. Turn off the pressure washer.

Step 5. Add pressure washer detergent to the soap tank.

While the pressure washer is turned off, remove the cap of the detergent tank. Fill the soap tank with a power washer cleaning solution specially designed for vinyl cleaning. Screw the cap back onto the tank and make sure that it is secure.

Step 6. Attach a soap nozzle to the pressure washer wand.

Detach the existing nozzle and replace it with a black nozzle, also known as a soap nozzle. Avoid attaching the nozzle while the pressure washer is on because this might cause severe injure, as the pressure of the water can cut the operator. After quick-connecting the nozzle, make sure that it is secure.

Step 7. Apply the cleaning solution to the vinyl siding.

Turn on the pressure washer and start spraying the vinyl siding starting from the bottom, going all the way to the top. Split the surface into smaller cleaning sections to avoid skipping any small parts. This direction of cleaning reduces the chances for stripes.

Step 8. Let the detergent soak in.

As every cleaning solution acts differently, make sure t read the label. Each manufacturer mentions a specific time that the solution needs to provide deep cleaning. Avoid leaving it to soak in for more than indicated, as this could cause the vinyl siding to deteriorate. Reapply another detergent layer if the detergent seems to dry to avoid deteriorating the vinyl.

Step 9. Rinse.

Turn off the pressure washer and connect a white nozzle to rinse the detergent off. Start from the top and finish at the bottom to avoid stripes.try taking overlapping stokes to make sure that all the detergent residue is removed.

Step 10. Pressure wash the nearby area.

After finishing the cleaning process, make sure to pressure wash the building’s nearby area with plain water to remove the dirt and detergent that came off the vinyl siding. Direct the residue to a sewer to get rid of it.

What Are Vinyl Siding Cleaners and Do You Need One?

Vinyl Siding Cleaner ReviewsVinyl siding cleaners are liquid cleaning agents used for cleaning dirt, mold, mildew, and debris off the vinyl and other surfaces – aluminum, concrete, stone, wood, and other house-building materials. Some vinyl siding cleaners can be applied only via pressure washers while some vinyl siding cleaners can be sprayed or applied manually on the surface.

Vinyl siding cleaners might be needed for the following reasons:

  • All-purpose cleaners are too weak and inefficient with cleaning mold, lichen, sap, bug and bird waste, mud, rain marks, and other outdoor calamities that build up on vinyl siding.
  • Some multi-purpose cleaners can be too strong or contain wrong ingredients that can make vinyl siding change color or damage it long-term.
  • Not all cleaning products can be used with pressure washers because they can’t create suds when blasted at 1,500 PSI or they will damage some parts of the pressure washer.

Vinyl Siding Cleaner Buying Guide

Factors such as ingredient list, formula, packaging type, garden and eco-friendliness, smell, and application should be considered when buying vinyl siding cleaners.

1. Ingredient List

Best vinyl siding cleaners are based on inorganic solvents like water and hydrogen peroxide or soaps with surfactants like alkyl sulfates that are unlikely to damage the vinyl material. Vinyl siding cleaners based on organic solvents and petroleum ethers – benzene, acetone, and THF should be avoided because they can be harmful to vinyl siding and can cause discoloration, haziness, or make the vinyl lose vitality and flexibility.

Bleach

Vinyl siding cleaners that contain ammonium chloride, chlorine bleach, and oxygenated bleach are efficient at removing fungi and mildew off vinyl surfaces. However, bleach-based vinyl siding cleaners can damage the pressure washer pump seals, which results in pressure washer pump placement. Bleach-based vinyl siding cleaners should be used with spray bottles rather than pressure washer cleaners.

2. Concentrated or Pre-diluted Formula

Vinyl siding cleaners are formulated as either concentrated or ready to use. Concentrated vinyl siding cleaners have to be diluted in water before being used, while the dilution ratio depends on the severity of dirt that needs to be cleaned. Between 3 and 10 gallons of diluted product is obtained for one gallon of concentrated vinyl siding cleaners, which makes them very economical. When using concentrated vinyl siding cleaners with pressure washers, the machine will dilute the cleaner automatically using another hose that connects it to the tap.

Pre-diluted vinyl siding cleaners are sold in smaller spray bottles or half a gallon bottles with built-in spraying mechanisms. As the water flows through the hose-end dispenser, it dilutes the vinyl siding cleaner and sprays it across the surface. Pre-diluted vinyl siding cleaners are pricier and less economical than concentrated siding vinyl cleaners.

3. Packaging Type

Vinyl siding cleaners’ packaging depends on the formula of the product. The best vinyl siding cleaners are specifically designed for pressure washer cleaning and come in small, 22fl oz spray bottles to 2.5-gallon jugs. Concentrated vinyl siding cleaners are sold in large bottles, ranging from 0.5 to 5-gallon containers, and come with a bottle cap that measures 1fl oz or another amount that helps with determining the right dilution ratio. Pre-diluted vinyl siding cleaners come in spray bottles or with a spraying adapter for garden or pressure washer hoses and are ready for application off-the-shelf.

4. Garden and Eco-Friendliness

Vinyl siding cleaners that contain benzene and other inorganic solvents can pollute waterways and impact aquatic life. Vinyl siding cleaners marked with “non-toxic”, “biodegradable”, or “EPA Safer Choice” labels minimize the impact they have on nature and are safe for the environment, humans, pets, and plants because they don’t contain carcinogens. Non-eco vinyl siding cleaners produce fumes when being sprayed and can be dangerous for the user and the environment.

5. Smell

Vinyl siding cleaners have different smells – more chemical or scented, while the choice of smell depends on personal preference.

Vinyl Siding Cleaner Application Methods

Vinyl Siding Cleaner Application Methods

Vinyl siding cleaners can be applied through a built-in applicator, using a bucket and a medium soft-bristled brush, or by spraying it on the surface using a pressure washer.

1. Built-in Applicator

Vinyl siding cleaners with built-in applicators – hose ends or spray heads can be connected to the tap, standard garden hose, or a pressure washer wand. Vinyl siding cleaners with built-in applicators are suitable for cleaning smaller problem areas on vinyl and not for removing sap, grease, or mildew off the whole siding. If vinyl siding cleaners are not designed to withstand the pressure of a pressure washer, the product can burst and cause burns.

2. Manual Application

Manual application of vinyl siding cleaners involves pouring the product into a bucket and applying it to the surface using a long-handled, medium-soft bristled brush. Cleaning the vinyl siding manually should never be done using scouring powder and other abrasive cleaners or using wire brushes that can damage the surface. Vinyl siding cleaners can be applied using foam nozzle tips or foam cannons as well.

3. Pressure Washing

Using vinyl siding cleaners with pressure washers is the quickest and most efficient method of removing tough stains and buildup off the siding. Only specifically labeled vinyl siding cleaners can create enough suds and should be used with pressure washers. Bleach-based vinyl siding cleaners can damage the inner parts of the pressure washers and should be avoided.

Using a pressure washer extension wand is recommended for reaching and cleaning higher stories of the house. Pressure washer brushes that combine the power of scrubbing bristles and pressurized water can be used for removing tough spots off the vinyl siding.

How to Clean Vinyl Siding with a Pressure Washer

Washing home exterior or vinyl siding with a pressure washer involves gathering the right equipment, preparing the surface, setting up the pressure washer, soaping and rinsing the surface. Surface cleaners and soap and detergents can be used with pressure washers for washing vinyl, cars, floors, and other surfaces.

1. Equipment Needed

Equipment needed for cleaning vinyl siding using a pressure washer is listed below:

  • Pressure washer
  • Pressure washer nozzle tips: a green 25-degree, a white 40-degree, and a black foaming tip
  • Vinyl siding detergent

Optional tools for cleaning vinyl siding using a pressure washer are listed down below:

  • Manual brush for applying soap can be used
  • Pressure washer extension wand to reach high spots
  • Pressure washer brush to scrub tough spots

More information about pressure washers and their accessories can be found on this link.

2. Before Starting

Before applying the vinyl siding cleaner to the surface, the gutters should be cleaned, the siding itself should be prepared, as well as the lawn, and safety precautions should be taken.

2.1. Cleaning gutters

Clogged gutters should be cleaned before washing siding, otherwise, dirt from gutters can overflow and make the siding dirty again.

2.2 Preparing the house

Washing home exterior using a vinyl siding cleaner and a pressure washer should be done on a mild day with low wind, during the spring or early summer. If the sun is too strong, the soap will dry before it is rinsed, which will reduce the efficiency of the vinyl siding cleaner. Strong wind can change the direction of the water stream and suds.

Any open outlets on the outside of the hose should be covered with plastic wrap as using a pressure washer around power lines can cause an explosion.

2.3 Preparing the lawn

Plants and bushes around the home should be watered before cleaning the siding with a pressure washer and vinyl siding cleaners. Watering the plans ensures the soap doesn’t stick and protects them from mildew.

2.4 Personal safety

Water-resistant clothes and boots, eye protection, and a breathing mask should be worn while cleaning house siding using a pressure washer and a vinyl siding cleaner to prevent breathing in soap chemicals or getting burned. Using a telescoping extension wand is recommended for cleaning two-story houses.

3. Setting Up

The water intake hose should be plugged into the electric pressure washer while gas-powered pressure washers should be filled with fuel. The vinyl siding cleaner should be poured through the siphon tube or in the pressure washer’s detergent tank. Pressure washers should be set to the lowest setting when cleaning vinyl siding.

4. Applying Soap

Applying SoapThe black nozzle tip with a lower pressure setting should be used for applying soap, a pressure washer brush, or a standard medium soft-bristled brush. The soap should be applied from the bottom of the house up and the whole wall should be soaped at once. Once the soap is applied, it shouldn’t be rinsed before the next 5 to 10 minutes.

5. Rinsing

For rinsing the soap, a green 25-degree nozzle tip that delivers more pressure and a smaller jet of water or a white 40-degree nozzle tip that delivers less pressure but a more focused jet of water should be used. The pressure washer’s nozzle should be 1 foot away from the siding when rinsing it and the water should be sprayed directly onto the surface, panel by panel, from the top down. Once rinsed, the siding should be left to dry naturally.
