Can You Pressure Wash a Stained Deck?

Maintaining your deck elevates your entire outdoor space and extends its life span. However, cleaning your deck can be a challenge, especially if you’re trying to preserve its stain or prepare it for a fresh application.

Perhaps you’re wondering if pressure washing will remove deck stains. Or you may be looking to learn how to clean a deck without a power washer. If so, you’ve come to the right place. In this article, we walk you through the benefits, risks, and best practices when power washing your deck and provide alternatives to safeguard your investment. Read on to get our expert insights.

What Is the Best Way To Clean a Stained Deck?

Learning how to clean a deck without a pressure washer can prevent potential damage to the stain. Thankfully, several effective and gentle cleaning techniques can restore your deck’s shine without compromising its protective coating. Here are some ways you can clean a deck without a pressure washer:

• Dish soap solution: A simple mixture of liquid dish soap and water is one of the safest ways to clean your deck. Combine one gallon of water with a quarter cup of dish soap, then scrub the surface with a soft-bristled brush. Rinse thoroughly to remove any residue.
• Vinegar solution: Mix equal parts white vinegar and water for an eco-friendly option. This solution is excellent for removing grease, dirt, and mildew while being gentle on the stain. Use a brush to scrub and rinse thoroughly.
• Oxygen bleach: For tougher stains, oxygen bleach is a natural alternative to chlorine bleach. Follow the package’s instructions to mix with water, scrub with a soft brush, and rinse away dirt and mildew.
• Baking soda paste: A paste of baking soda and water effectively removes stubborn grime and odors. Apply it to trouble spots, scrub gently, and rinse.

Can You Pressure Wash Stained Wood?

Will a pressure washer remove deck stain? The answer is yes, if the pressure isn’t carefully managed. Pressure washing is a popular method for cleaning decks. However, when it comes to stained wood, there are a few important factors to consider. While it’s possible to pressure wash stained wood, improper use of a pressure washer can cause damage to the wood and the stain, leaving you with more repairs than you bargained for. When not done correctly, pressure washing can lead to several issues, including:

• Wood splintering: High-pressure streams can cause the wood fibers to lift, leaving the surface rough and damaged.
• Stain removal: If the pressure is too strong, it can strip away the protective stain, leaving your deck vulnerable to the elements.
• Tiger stripping: Inconsistent pressure or improper techniques can create unsightly lines on the deck surface, which are difficult or impossible to sand out.
• Denting and fading: Softwoods are particularly prone to dents, while discoloration can occur if natural oils are stripped from the wood.

So, you can pressure wash a wood deck, but it’s not always necessary. Light cleaning methods can often suffice without the risks associated with pressure washing. If you do choose to pressure wash, it’s important to prepare properly and use a low-pressure setting designed for wood surfaces.

Preparing Your Deck for Pressure Washing

Before you begin pressure washing your deck, there are a few simple steps that can protect your investment.

Step 1: Inspect and Clear the Area

Inspect your deck for loose boards, protruding nails, or splintered wood. Repair these issues to prevent further damage during washing. Clear the deck of furniture, planters, and grills. This provides unrestricted access and prevents debris from being blown onto the deck. Use tarps or plastic sheeting to protect surrounding vegetation and any surfaces you don’t want exposed to water spray.

Step 2: Choose the Right Equipment

Opt for a power washer with adjustable pressure settings. For softwoods, such as cedar or pine, use 500-600 psi. For hardwoods, such as ipe or garapa, a psi of up to 1200 is suitable. Use a fan tip with a 40-to-60-degree spread to distribute water pressure evenly and minimize the risk of damage.

Step 3: Perform a Prewash Cleaning

Use a broom or leaf blower to remove dirt, leaves, and other loose debris. Apply a gentle deck cleaner to areas with grease, mold, or mildew. Let it sit for a few minutes to loosen grime before washing.

Step 4: Use Safety Precautions

Use safety goggles, gloves, and non-slip footwear to protect yourself during the process. Before starting, test the pressure washer on an inconspicuous area of the deck to make sure it won’t damage the surface.

By following these preparatory steps, you’ll be ready to pressure wash and refresh your deck without risking unnecessary damage.
