A wood deck in New Orleans rarely gets a long dry spell. Shade from nearby trees and frequent summer storms keep the boards damp, so mildew and algae turn a deck gray-green and slick well before the wood itself looks worn out.
Pressure washing clears that growth in a fraction of the time hand scrubbing takes, but wood is easy to damage. Too much pressure raises the grain and leaves fuzzy, splintered boards. Here’s a guide from Big Easy Pressure Washing on cleaning a deck safely, step by step, with notes on what our climate changes.
Safety Precautions and Equipment
Cleaning your deck with a pressure washer can be a quick and effective way to remove dirt, grime, and stains. However, it is important to take safety precautions and use the right equipment to avoid damaging your deck or injuring yourself. Before starting, make sure to wear protective gear such as eye and ear protection, gloves, and non-slip shoes. Also, check the pressure washer’s manual to make sure you are using the correct nozzle and pressure setting for your deck material.
Preparing the Deck
Before cleaning your deck with a pressure washer, it is important to prepare the deck properly. First, remove any furniture or objects from the deck to avoid damaging them or getting them dirty. Next, sweep the deck thoroughly to remove any loose dirt or debris. If there are any tough stains or mildew, consider using a deck cleaner or a mixture of water and bleach to pre-treat the area before pressure washing. It is also important to protect any nearby plants or landscaping by covering them with plastic sheeting or watering them thoroughly before cleaning.
Setting Up the Pressure Washer
When it comes to cleaning your deck with a pressure washer, the first step is to set up the pressure washer correctly. Start by making sure the power supply is connected properly and that there are no leaks in the hoses. Next, attach the appropriate nozzle for the job. For deck cleaning, a 25-degree nozzle is recommended. Adjust the pressure accordingly, starting with a low setting and gradually increasing it until you find the right pressure for your deck.
Testing the Pressure Washer
Cleaning your deck with a pressure washer is a great way to get rid of built-up dirt and grime. However, before you start, it is important to test the pressure washer on a small, inconspicuous area of your deck to make sure it does not damage the wood. Begin by sweeping any loose debris off your deck and then pre-soak it with a deck cleaning solution. Allow the solution to sit for a few minutes before using the pressure washer to rinse it off.
Cleaning Techniques
Cleaning your deck with a pressure washer requires a few key techniques to achieve the best results. First, it is important to choose the right pressure washer for the job, with a high enough pressure and flow rate to effectively remove dirt and grime. Next, you should start by sweeping or blowing off any loose debris from the deck surface. Then, apply a deck cleaning solution or detergent to the surface and let it sit for a few minutes to loosen any stubborn dirt or stains.
Removing Stubborn Stains
Cleaning a deck with a pressure washer is an effective way to remove stubborn stains. First, prepare the deck by removing any furniture or debris and sweeping it clean. Next, choose a pressure washer with the appropriate pressure and nozzle for your deck material. Start with a low pressure setting and gradually raise it as necessary. Begin at one end of the deck and work your way across, being careful not to damage the wood.
Rinsing and Drying
Cleaning your deck with a pressure washer is a great way to get rid of dirt, grime, and other debris that can accumulate over time. The first step in this process is to thoroughly rinse the deck with water to remove any loose debris. Once the deck is rinsed, it is important to dry it thoroughly to prevent any moisture from causing damage or rotting the wood. This can be done by using a leaf blower or allowing the deck to air dry.
What Changes When You Wash a Deck in New Orleans Humidity?
The steps above work anywhere, but a few things matter more here. The growth you’re removing is usually mildew and algae, not just dirt. A deck cleaner with enough dwell time does most of that work, so you can keep the pressure low and let the rinse carry the growth away.
Drying also takes longer. Wood has to be thoroughly dry before stain or sealer goes on, and after a wash in muggy weather that can mean waiting through several dry days, not one afternoon. Check the forecast and plan the wash for the start of a dry stretch.
Shaded boards under live oaks or along the north side of the house grow back fastest. Those sections may need a light cleaning every season, while a deck in full sun can go much longer between washes.
If your deck is composite, the rules change again, and our guide to cleaning composite decking covers it. For decks in Mandeville, Madisonville, and across the metro, a low-pressure soft wash with a wood-safe cleaner is often the safer choice for the wood.
Post-Cleaning Maintenance
Cleaning your deck with a pressure washer is a great way to keep it looking new and fresh. After you have finished the cleaning process, it is important to take some post-cleaning maintenance steps to keep your deck in good condition. First, allow the deck to dry completely before applying any sealant or stain. This will prevent any moisture from being trapped in the wood and causing rot or mold.
