How to Clean Vinyl Siding in 3 Easy Steps

Over time, the once vibrant and pristine vinyl siding on your home can start to look a little worse for wear. That bright white or bold blue hue you fell in love with can become dull and faded, overtaken by dirt, grime, and even mildew. But don’t worry - with just a little effort, you can have your siding looking brand new again. 

Discover why vinyl siding maintenance matters and when to call professionals. We'll then explore simple steps to clean your siding, from removing dust and pollen to tackling mildew streaks. Learn the tips and tricks to restore your home's exterior to its like-new appearance and keep it shining year-round.

Why Vinyl Siding Needs Regular Cleaning

Vinyl siding is an incredibly popular choice for homeowners thanks to its durability, low maintenance, and wide variety of style options. Unlike wood or stucco, vinyl siding won't rot, warp, or crack over time. And a simple rinse with the garden hose is usually all it takes to keep it looking fresh.


However, that doesn't mean vinyl siding is completely immune to the elements. Over time, your home's siding can accumulate all sorts of dirt, debris, and organic growth that can dull its appearance. Here are some of the main culprits:


  • General Grime and Dirt Buildup: Wind, rain, and even passing traffic can blow dust, pollen, and other airborne particles onto your siding, creating an overall dull, faded look.
  • Stubborn Stains: Things like grease, oil, bird droppings, and other stubborn stains can mar the surface of your siding if left untreated.
  • Algae and Mildew Growth: Damp, shaded areas of your home's exterior are prime breeding grounds for unsightly green algae and black mildew growth.


While vinyl siding is designed to be low-maintenance, regular cleaning is still important to keep it looking its absolute best. Neglecting your siding for too long can lead to deeper stains and tougher-to-remove buildup that requires more elbow grease (or even professional intervention) to address.

When to Call in a Professional Siding 

In most cases, homeowners can handle the task of cleaning vinyl siding on their own using some simple methods that we are going to discuss. But there are a few scenarios where it may be best to call in a professional siding contractor for assistance:


  • Severe Staining or Mildew
  • Damaged or Warped Siding
  • Hard-to-Reach Areas
  • Unsure About Proper Cleaning Methods

Gather Your Supplies for Siding Cleaning

If you've assessed that you can handle the cleaning yourself, the next step is to gather your supplies. Luckily, the items needed to clean vinyl siding are inexpensive and easy to find. Here's what you'll want to round up:


  • Bucket: You'll need a large bucket to mix your cleaning solution.
  • Soft-Bristle Brush: A brush with gentle, soft bristles is essential for scrubbing the siding without causing any damage.
  • Garden Hose: A garden hose with an adjustable nozzle will allow you to rinse the siding thoroughly.
  • Mild Detergent: Stick to a mild dish soap or laundry detergent - no harsh chemicals needed.
  • Trisodium Phosphate (TSP): This cleaning agent helps cut through tough grime and stains.
  • Bleach: A small amount of household bleach can be added to the cleaning solution to address mildew growth.


With these basic supplies on hand, you'll be ready to tackle even the dirtiest vinyl siding. And the good news is, you likely already have most (if not all) of these items in your home already.

Step-by-Step Siding Cleaning Instructions

Now that you've gathered your supplies, it's time to get to work. Cleaning vinyl siding is a pretty straightforward process, but it's important to follow the right steps to ensure you don't accidentally damage the material. Here's a detailed walkthrough:

Mix the Cleaning Solution

In your large bucket, combine the following ingredients:


  • 1/3 Cup Mild Detergent
  • 2/3 Cup Trisodium Phosphate (TSP)
  • 1 Quart of Household Bleach
  • 3 Quarts of Water


This solution is specifically formulated to tackle the most common types of siding stains and buildup, from general grime to stubborn mildew. Just be sure to mix it up thoroughly before you begin.

Scrub the Siding

Dip your soft-bristle brush into the cleaning solution, making sure to saturate the bristles. Then, start scrubbing the siding in small, gentle circular motions, working from the bottom up.


It's important to avoid applying too much pressure, as this could potentially damage the vinyl material. Take your time and focus on one section at a time, making sure to cover the entire surface evenly.

Rinse Thoroughly

Once you've scrubbed the entire siding, it's time to rinse everything off. Attach your garden hose to the siding and spray from top to bottom, making sure to thoroughly rinse away all of the cleaning solution.


Be especially careful in areas where the siding meets trim, windows, or other adjoining surfaces  you want to prevent any soapy runoff from leaving streaks or water spots.

Allow to Dry Completely

After the final rinse, let the siding air dry completely before moving on. This will help prevent any unsightly water stains from forming as the surface dries.


And with that, your vinyl siding should be looking good as new! The combination of the mild detergent, TSP, and bleach in the cleaning solution works wonders to lift away even the toughest grime, mildew, and stains.
