Soft Washing Your Deck: The Best Way to Clean for Summer

Revive your deck with Keenwick's safe and effective soft washing.

Summer’s here, and with it comes the pull to spend more time outside. The deck often becomes your favorite spot for weekend BBQs, quiet reading sessions, or late-evening chats. But if it’s covered in grime, mold, or old stains, it might feel more like a chore than a retreat. Hiring a trusted soft washing company can make all the difference. Many homeowners are still stuck on pressure washing, not realizing the damage it can cause. Soft washing offers a smarter alternative that gets your deck clean without tearing it apart.

What Exactly Is Soft Washing? 

Let’s keep it simple. Soft washing is a technique that uses low water pressure combined with specialized solutions. It targets dirt, algae, mold, and mildew deep down, not just at the surface. This method relies more on safe chemical reactions than brute force.

Key traits of soft washing: 

  • Gentle water pressure under 500 PSI
  • Uses biodegradable, plant-safe detergents
  • It kills microbes instead of spreading them
  • Ideal for wood, composite, vinyl, and painted surfaces

The goal isn’t to blast things off. The goal is to clean with precision. Soft washing gives your deck a deep clean without weakening the wood or stripping protective finishes.

Pressure Washing vs Soft Washing: The Deck Showdown 

Pressure washing, on the face of it, appears to be doing more. It feels satisfying to watch the blast clean up dirt in seconds. But that blast comes at a cost. On wood decks, high pressure can gouge surfaces, raise the grain, or leave visible marks. It might even force water deep into the wood, leading to rot.

Here’s what pressure washing can do to your deck: 

  • Damage softwood or old composite planks
  • Remove paint or sealants prematurely
  • Create uneven discoloration
  • Push mold spores deeper, causing regrowth

Soft washing, by contrast, treats the problem at its source. Instead of rough handling, it uses the right mix of chemistry and care, leaving your deck cleaner and lasting longer.

The Soft Washing Process: Step-by-Step Breakdown 

Wondering how soft washing works? Here’s a straightforward look at what the process involves.

1. Evaluation and Setup 

Professionals start by checking the deck’s condition. They note loose boards, exposed nails, and signs of rot. Furniture is moved aside, and delicate plants are covered for protection.

2. Solution Application 

The cleaning solution, often a mix of mild bleach and biodegradable surfactants, is applied using a low-pressure sprayer. This solution clings to surfaces and begins breaking down contaminants.

3. Let It Sit 

Patience matters. The solution needs time to sink in. During this dwell period, the magic happens as the solution dissolves dirt, mold, algae, and other buildup.

4. Gentle Rinse 

Finally, the surface is rinsed with clean water at low pressure. There’s no forceful stripping involved. The result is a visibly brighter, safer deck ready to enjoy.

Top Reasons to Choose Soft Washing for Your Deck 

This isn’t just about aesthetics. While your deck will look fresher, soft washing improves its longevity and keeps it healthier.

Helps Wood and Materials Last Longer

There’s no aggressive pressure involved, and hence your deck stays intact. The surface doesn’t get rough, splintered, or prematurely worn out.

Gets Rid of Deep-Seated Mold and Algae 

The soft washing solution doesn’t just wipe the surface. It attacks mold and bacteria at the root, preventing rapid regrowth and keeping the area cleaner for longer.

Safe for Families, Pets, and Plants 

Most soft washing solutions used by professionals are eco-conscious. They’re biodegradable and designed to be safe around kids, animals, and landscaping.

Less Maintenance, Fewer Repairs 

Since soft washing avoids surface damage, you’ll spend less time and money sanding, staining, or replacing boards down the road.

When Should You Get Your Deck Soft Washed? 

You don’t have to wait until your deck is covered in moss to take action. Timing matters, especially if you want the results to last through the season.

Best times to schedule soft washing: 

  • Spring or early summer before outdoor use increases
  • After a rainy season, when algae thrive
  • Before applying a fresh coat of sealant or stain
  • When black or green patches start appearing

Working with a professional soft washing company ensures the timing is right and the job is done thoroughly.

What are the Warning Signs That Your Deck Needs Soft Washing? 

Some signs are obvious. Others sneak up slowly. Keep an eye out for these:

  • Green or black streaks on the surface
  • Musty smell lingering after rain
  • Slippery areas due to algae or moss
  • Faded or uneven color patches
  • A general dingy or dull appearance

The sooner you spot these signs, the better. Waiting too long can lead to surface deterioration, insect problems, or worse. One solid soft washing session can turn it all around.

DIY vs Professional Soft Washing: Is It Worth Doing Yourself? 

The short answer? Not really. Soft washing is all about getting the balance right. Too weak, and it won’t clean. Too strong, and it could bleach or damage your deck.

Why going pro is the better option: 

  • Professionals use the right nozzle and dilution ratios
  • They know how long to let solutions dwell
  • The risk of harm to plants, paint, or pets is minimized
  • They spot issues like rot or water pooling before cleaning

Hiring a pro saves time, helps you avoid risks, and gets better results. DIY kits lack precision, and online recipes can be hit or miss. It’s not worth gambling on your outdoor space.

Choosing a Reliable Soft Washing Company 

Not every cleaning service is equipped for soft washing. Choosing the right provider can make or break the outcome.

Look for these signs of a good soft washing company: 

  • Experience with deck cleaning, specifically
  • Transparent explanation of their process
  • Use of eco-friendly, non-corrosive solutions
  • Insurance coverage and customer reviews
  • Before-and-after photo samples of past work

Don’t be shy about asking questions. A reliable company will walk you through the process and address any concerns upfront.

Aftercare: Keep Your Deck Clean for Longer 

Once your deck is cleaned, maintenance helps extend the results. It doesn’t have to be time-consuming, just consistent.

Simple tips for post-soft-washing care: 

  • Sweep off leaves and debris regularly
  • Avoid placing rugs or planters that trap moisture
  • Keep the surrounding bushes trimmed to reduce shade
  • Re-seal or stain the wood when needed
  • Address spills and bird droppings quickly

With minimal upkeep, your deck looks fresh and feels safer.

Conclusion: A Cleaner Deck Makes a Better Summer 

There’s nothing like stepping out onto a clean, welcoming deck at the start of summer. It sets the tone for everything, from family dinners to quiet moments under the stars. Soft washing is a smart, effective way to bring your deck back to life without risking damage. It’s gentle, deep-cleaning, and gives results that last.

Trust the job of a skilled soft washing company that understands how to care for your specific material and space. When the dirt’s gone, and the wood shines, you’ll be glad you skipped the pressure and went with a method that respects your home.
