Your deck should be a place to relax—not a surface covered in algae, mildew, dirt, and weathered wood. Riverside Pressure & Softwash provides professional deck cleaning services that safely restore the appearance of wood and composite decking without causing unnecessary damage.


We carefully match the cleaning method to your deck's material, helping remove years of buildup while preparing the surface for continued enjoyment or future staining and sealing.

Cleaning Wood Requires Experience

Why Deck Cleaning Is Different Than Pressure Washing

A deck is one of the most delicate exterior surfaces around your home.

Unlike concrete or brick, wood is made up of natural fibers that can be permanently damaged by excessive pressure or improper cleaning products.


Unfortunately, many people assume the quickest solution is to spray the deck with bleach or blast it with high-pressure water.


Neither approach delivers the best long-term results.

At Riverside Pressure & Softwash, we use professional wood cleaning methods designed to remove dirt, algae, mildew, weathering, and old contaminants while protecting the integrity of the wood itself.

Know the Warning Signs

Signs Your Deck Needs Professional Cleaning

Missouri weather can take a toll on your deck throughout the year. Moisture, sunlight, pollen, leaves, and foot traffic gradually wear down the surface and allow organic growth to develop.

Your deck may benefit from professional cleaning if you notice:

  • Green algae or mildew
  • Slippery walking surfaces
  • Gray or weathered wood
  • Black staining
  • Dirt embedded in the grain
  • Pollen buildup
  • Leaves trapped between deck boards
  • Uneven coloring
  • A deck that looks older than it really is
  • Preparing for staining or sealing


Routine cleaning not only improves appearance but also helps create a safer, more enjoyable outdoor space.

Professional Cleaning Makes the Difference

Why We Don't Use Bleach or Excessive Pressure on Wood Decks

One of the biggest misconceptions in deck cleaning is that bleach is the best way to remove algae, mildew, and discoloration.


While bleach may make a deck appear cleaner for a short time, it can also dry out the wood, damage natural wood fibers, create an uneven appearance, and reduce the wood's ability to absorb stain evenly.


High-pressure washing can be just as harmful. Too much pressure can gouge the wood, create permanent wand marks, raise the grain, and splinter the surface, leaving your deck rough and more susceptible to future weathering.


At Riverside Pressure & Softwash, we believe cleaning should improve the condition of your deck—not contribute to its deterioration.


That's why we use professional wood cleaning products and carefully controlled pressure to safely restore your deck while protecting the integrity of the wood.

The Right Chemistry Matters

Professional Wood Cleaning Products for Better Results

Different contaminants require different cleaning solutions.

Rather than relying on household bleach, we use professional products selected specifically for wood restoration.

Sodium Metasilicate

Sodium metasilicate is an effective wood cleaner that helps loosen dirt, algae, mildew, old finishes, and organic buildup without causing the damage commonly associated with bleach. It prepares the wood for restoration while preserving its natural structure.

Oxalic Acid

After cleaning, oxalic acid helps neutralize the cleaning process while brightening the wood and restoring its natural appearance. It also helps reduce tannin stains and other discoloration that can develop over time.

Using these professional products allows us to clean more effectively while producing a more consistent, natural-looking finish.

FAQs

  • Is pressure washing safe for wood decks?

    Not by itself. Excessive pressure can damage wood fibers, leave permanent marks, and shorten the life of your deck. We use controlled pressure and professional wood cleaning products designed specifically for deck restoration.

  • Why shouldn't bleach be used on decks?

    Bleach can dry out wood fibers, create uneven coloring, and make it more difficult for stain to absorb evenly. Professional wood cleaners provide better long-term results while helping protect the wood.

  • Do you clean composite decking?

    Yes. Composite decks require a different cleaning approach than natural wood, and we adjust our process accordingly.
