Pressure treated wood decks are a popular choice for homeowners due to their durability and resistance to rot and decay. However, over time, these decks can accumulate dirt, grime, and mildew, making them look dull and unattractive. To keep your pressure treated wood deck looking its best, regular washing is essential.

Before you begin, it’s important to gather the necessary materials. You will need a pressure washer, a scrub brush, deck cleaner or a mixture of water and mild detergent, safety goggles, gloves, and protective clothing. Safety should always be a priority when working with a pressure washer, so make sure you follow all manufacturer instructions and guidelines.

Start by removing any furniture or plants from the deck and sweeping away any loose dirt or debris. Then, use a hose to wet the entire deck surface. This will help loosen any embedded dirt and make the cleaning process more effective.

Next, apply a deck cleaner or a mixture of water and mild detergent to the deck surface. Allow the cleaner to sit for a few minutes to penetrate the dirt and grime. Then, using a scrub brush or a pressure washer with a low-pressure tip, scrub the deck surface in the direction of the wood grain. Be careful not to apply too much pressure, as this can damage the wood.

Clear the deck

Begin by clearing the deck of all furniture, plants, and any other objects that may obstruct the cleaning process. This will allow you to have uninterrupted access to the entire surface of the deck.

Sweep or blow off loose debris

Using a broom or a leaf blower, remove any loose debris such as leaves, dirt, or sticks from the deck surface. This will help prevent these materials from interfering with the cleaning solution and ensure that the deck is ready for a thorough cleaning.

Protect plants and surrounding areas

If you have plants or other sensitive areas near your deck, it is crucial to take measures to protect them during the cleaning process. Cover the plants with plastic sheets or tarps to prevent them from coming into direct contact with the cleaning solution. Additionally, wet down any nearby surfaces that could be affected by the cleaning solution to dilute its impact.

Gather necessary materials

Before starting the cleaning process, gather all the necessary materials. This may include a pressure washer with appropriate nozzles, a garden hose, a scrub brush, protective eyewear, gloves, and a deck cleaning solution. Consult the manufacturer’s instructions for your specific pressure washer and deck cleaning solution to ensure you have the correct materials.

Removing Furniture and Plants

Before you begin washing your pressure treated wood deck, it’s important to remove all furniture and potted plants from the area. This will give you a clear surface to work with and prevent any potential damage to your belongings.

First, carefully move any outdoor furniture or accessories off the deck. This includes chairs, tables, umbrellas, and any other items that are not anchored to the deck. Be sure to lift rather than drag the furniture to avoid scratching or damaging the wood surface.

Next, remove any potted plants or planters from the deck. These can be placed on the ground or on a lawn nearby. Water the plants as needed and keep them in a shaded area to prevent stress from direct sunlight.

Finally, check for any other items that may need to be removed, such as toys, grills, or decorations. Keep in mind that washing your deck may involve the use of water and cleaning solutions, so it’s important to keep these items away from the work area for safety reasons.

By removing furniture and plants before washing your pressure treated wood deck, you’ll ensure a more efficient and effective cleaning process, while also protecting your belongings from potential damage.

Gently Sweeping the Surface

Before proceeding with washing the pressure treated wood deck, it is important to start by gently sweeping the surface to remove any loose dirt, debris, and leaves. This step will help prevent scratching or damaging the wood during the cleaning process.

Use a broom with stiff bristles or a deck brush to sweep in the direction of the wood grain. Start at one end of the deck and work your way towards the other end, ensuring that you cover all areas.

Make sure to pay extra attention to areas where dirt and debris tend to accumulate, such as corners, gaps between boards, and underneath furniture. Use a hand brush or a putty knife to remove any stubborn dirt or debris that may be lodged in these areas.

Avoid using a wire brush or abrasive scrubbing pads, as they can leave scratches on the surface of the wood. The goal is to gently remove surface dirt without causing any damage.

By thoroughly sweeping the deck before washing, you will ensure that the cleaning process is more effective and that the pressure treated wood is properly prepared for the next steps.
