Using A Pressure Washer On Vinyl

Not all vinyl siding manufacturers recommend pressure washing their products, so it’s best to check first to avoid voiding the warranty. Once you’re sure it’s OK, adjust the pressure to no more than 1,200 psi and fit the wand with a 40-degree nozzle. At that pressure, you may have trouble removing well-established patches, especially from high places that require you to work from a ladder. For this reason, it’s a good idea to scrub with a disinfecting cleaner and rinse with the pressure washer. Remember to keep the wand horizontal or tilted downward to avoid forcing water under the vinyl slats.

How To Make The Best Homemade Vinyl Cleaner

Vinyl siding usually cleans up easily with nothing more than a homemade vinyl siding cleaner of soap and water, and a yearly scrubbing will keep it looking new. For basic vinyl siding wash cleaning, use general-purpose vinyl siding cleaning solution mixed with warm water. To make your own vinyl cleaner you’ll need:

  • A general-purpose cleaner like Dawn Dish Soap or Soft Scrub
  • Bucket full of warm water
  • Large sponge

What Not To Do When Cleaning Vinyl Siding

  • Using undiluted and un-targeted products: Organic solvents or undiluted chlorine bleach, and furniture polishers can damage the surface so best be avoided.
  • Abrasive scrubbers: The likes of steel wool can scratch and cause damage when cleaning vinyl siding. Soft bristles + elbow grease is the answer.
  • Too strong pressure washing: As mentioned, opt for the garden hose instead but if you must use your pressure washer, keep it to a minimum strenth.
  • Not cleaning with care: Go carefully around windows, doors, any dryer vents and more openings so that water doesn’t go where it shouldn’t.

Mold and mildew on vinyl siding is a common problem that can be remedied with some effort and the right cleaning materials. Over time, mold can grow on a vinyl siding because it has not been cleaned for a while. Accumulated dirt, grime, grease and plant material can also provide the perfect breeding ground for mold. The methods described below will give you an idea about the vast number of cleaning methods you can use.

1 Rinse the Siding with Water

If the mold has just started accumulating on the siding and you discover it on time, you can do a quick cleaning with water. Use a garden hose for this purpose. Remember to always work from the bottom up. Whether you use a garden hose or a pressure washer, never direct the water upwards. This will cause the water to collect behind the siding and possibly contribute to rot and other problems.

2 Apply Cleaning Solution with a Long Handled Brush, Sponge or Soft Cloth

3 Use Windex for Small Spots

If you have mold or mildew in small areas or patches, try cleaning it with Windex or another similar household cleaning solution. Before applying any cleaner, test the solution on an inconspicuous piece of the siding.

4 Apply a Solution of Vinegar and Water

5 Use a Pressure Washer

Does Vinegar Kill Mold

White vinegar is a mildly acidic product that cleans, deodorizes, and disinfects. It can also kill 82% of mold species, including black mold, on porous and non-porous surfaces. You can use it safely on most surfaces, and its offensive odor goes away quickly. Pour undiluted white vinegar into a spray bottle.

Clean Wood Siding With A Garden Hose

If youre using a pressure washer, youll probably do a final rinse with a garden hose, which wont damage the siding and washes away all the chemicals. However, you can also buy an attachment with a chemical cleaner that is hooked up to the garden hose and used to distribute the solution on the siding. The pressure from the hose isnt strong enough to knock down all of the grime, which means youll have to use the scrub technique to remove the more stubborn areas of grime.

When using a garden hose, it is recommended to use a solution of water and cleaner, which is often a mild detergent, and scrub the siding with a sponge, cloth or a soft-bristled brush. Be careful not to push too hard with a brush as this can damage the siding. As a final step, use the garden hose to rinse off any remaining solution and debris.

Removing Mildew From Vinyl Siding

As rainwater and condensation accumulate on vinyl siding, it can develop black spots of mold and mildew. Standard household cleaners won’t necessarily remove mildew from siding, but a solution of bleach or vinegar should do the job. If you use bleach, protect the plants nearby from runoff by covering them with plastic dropcloths. A power washer is the most efficient tool for the job, but not all siding can handle the water pressure, so check with the manufacturer or test a small, inconspicuous area to determine whether you can use a power washer without damage.


Turn off the electricity to any outlets and lamps on the walls you plan to clean. Cover them with plastic sheeting, and secure the sheeting to the wall with duct tape.


Mix a solution of 3 parts distilled white vinegar to 7 parts water in a bucket. Alternatively, mix a solution of 1 part household bleach to 4 parts water.


Dip a long-handled, soft-bristle brush into the solution. Gently scrub any visible mildew spots.



Tip the remaining solution out of the sprayer and back into the bucket. Rinse the sprayer quickly and refill it with clean water. Spray the wet strip of vinyl with the water from the top of the house downward to rinse off the solution.


Repeat the process with the next 5 feet of siding. Continue in this fashion until you have cleaned the entire affected area.

    How To Remove Mold From Vinyl Siding

    Mold and mildew are basically two words for the same thing, and cleaning them from the side of a house is usually easy with a power washer. That technique is problematic when cleaning vinyl siding, though, because a pressure washer can force water under the siding.

    That doesn’t mean you can’t use a pressure washer, but you have to keep the pressure low, so you should scrub the siding with a solvent first.

    Products And Tools Youll Need To Clean Vinyl Siding:

    For the Love of Gardening: Dirt, Mold, Moss and Algae on Vinyl?
    • Soft-bristled brush or broom: You want the bristles to be fine enough to get debris from the siding without damaging its surface effectively. A brush is perfect for the lower sections of your siding, while a broom, or brush with a long handle, is effective at reaching those higher parts.
    • Soft cloth: We recommend using microfiber cloths, as these wont scratch or chip the surface of your vinyl siding. Ensure you have plenty on-hand depending on how dirty your vinyl siding is, you may go through a lot!
    • General-purpose cleaner, such as Dawn Dish Soap or Palmolive: A simple solution of dish soap and warm water can work wonders as a siding wash, plus it wont wear away at the vinyl sidings protective coating.
    • Commercial house siding cleaner, such as Wet & Forget Roof and Siding Cleaner or Simple Greens House and Siding Cleaner: For a heavy-duty clean, look to products specially formulated for cleaning vinyl siding. Avoid harsh products like straight chlorine bleach, paint thinner, acetone , furniture cleaner, and spot or paint remover.
    • Bucket: Youll need this to mix your house siding cleaner and to take with you as you move around the house.
    • Garden hose: Use a hose to rinse off each section as you clean to avoid residue and streaking. Make sure your garden hose is long enough for the water to reach the highest sections of your vinyl siding.

    Tips For Maintaining Your Homes Vinyl Siding

    Vinyl is an incredibly popular siding material because its resilient, long-lasting, and affordable. To keep your home looking great without hurting plants or damaging moisture barriers below the siding, here are routine maintenance tips to keep in mind.

    • Inspect your vinyl siding at least twice a year for any cracks, dents, or missing pieces.
    • Remove any spider webs, dirt, or debris from the surface of your siding with a broom or brush.
    • Replace any broken or damaged vinyl panels as soon as possible to prevent moisture and insect infiltration.
    • If you have plants below your siding, make sure to trim them back at least 12 inches from the houses edge.
    • Regularly clean your gutters so that water does not drain on top of your vinyl siding and cause it to peel or warp.
    • Use a natural vinyl siding cleaner first before resorting to commercial cleaning solutions. Consider environmentally friendly options if you must use something for tough dirt and mildew.
    • For thorough cleaning of your siding, avoid using household bleach. Experts caution against chlorine bleach and oxygen bleach as they can deteriorate the vinyl and harm your landscaping.
    • Be careful when using a pressure washer to remove stubborn stains. Use the proper technique to not damage any plants underneath the siding.

    Remove All Potential Source Of Moisture

    • Dark, moist places are ideal for mold growth, so trimming trees and shrubs and providing as much direct sunlight as possible on the siding helps prevent mold growth.
    • As climbers, vines, and moss cover siding, they prevent natural light from reaching the surface. This leads to mold developing rapidly without anyone noticing it.
    • When your gutters are clogged or improperly sloped, they can leak or overflow. This can lead to water damage to your siding, roof, and foundation.
    • Ensure sprinklers do not reach your siding as continuous dampness can cause mold spores to attach and grow. Always make sure that sprinklers are placed far enough away that the siding is not in the splash zone.
