Understanding What Driftwood Is and Why Cleaning Matters

Driftwood is wood that has been carried by rivers, lakes, or ocean currents and deposited on shores. It comes from trees that have fallen into water, been cut down near waterways, or washed away during storms and floods. The wood becomes smooth and weathered as it tumbles through water and sand over months or years. When you find driftwood on a beach or riverbank, it may look clean on the surface, but it often contains hidden materials that need removal before you bring it indoors.

Salt, sand, mud, algae, and small organisms can live on or inside driftwood. If you plan to use driftwood for decoration, crafts, or furniture, these materials can cause problems. Salt can damage finishes and attract moisture. Sand particles can scratch surfaces or fall onto floors. Algae and bacteria may continue to grow if conditions remain damp. Additionally, driftwood can harbor insects, small crustaceans, or other creatures that may have nested inside crevices during its time in water.

Cleaning driftwood protects your home and makes the wood safer for handling, especially if children or pets will be near it. The cleaning process also helps you inspect the wood for damage, rot, or structural weakness. A properly cleaned piece of driftwood will last longer as a decorative item and will look more polished in your home.

Practical takeaway: Before bringing any driftwood indoors, plan to spend a few hours cleaning it. The effort prevents salt damage, removes pests, and prepares the wood for whatever purpose you have in mind.

Gathering Supplies and Preparing Your Workspace

You do not need expensive equipment to clean driftwood at home. Most supplies are common household items or inexpensive tools available at hardware stores. Start by gathering a stiff-bristled brush, which works well for scrubbing away dried salt, algae, and surface debris. A wire brush or old toothbrush can reach into small crevices. You will also need water—either from a garden hose or large bucket—and mild dish soap. Avoid harsh chemicals unless the wood has deep staining or stubborn algae growth.

Additional items that prove useful include old towels or rags for drying, a scraper or old putty knife for removing thick buildup, and sandpaper in various grits (80, 120, and 220 grit work well for most jobs). If you plan to use water treatments, white vinegar and baking soda are natural options that work without toxic fumes. For larger pieces or heavily soiled wood, you might consider renting a pressure washer, though caution is needed because high pressure can damage delicate wood or force water into cracks.

Your workspace should be outdoors or in a garage with good drainage. Cleaning driftwood produces dirty water, sand spray, and debris. A concrete driveway, patio, or gravel area works well. Lay down old towels or cardboard to catch sand and contain the mess. If working in a garage, place wood on a tarp to protect the floor. Wear old clothes you do not mind getting wet and dirty, and consider wearing gloves to protect your hands and reduce exposure to bacteria or irritants that may be on the wood.

Practical takeaway: Set up your workspace before you start, gather all supplies nearby, and wear protective clothing. This planning prevents interruptions and keeps your home clean during the project.

Step-by-Step Cleaning Process for Driftwood

Begin by doing a dry inspection of the driftwood. Look for loose bark, visible cracks, embedded shells, or other attached objects. Use your stiff brush to remove any loose debris, sand, and dry algae. Pay special attention to crevices, joints, and hollowed sections where sand and small creatures may hide. A dry brushing session removes perhaps 30 to 50 percent of surface material without using water, making the wet-cleaning stage faster and more effective.

Next, rinse the driftwood thoroughly with water. Use a garden hose on low to medium pressure, or submerge smaller pieces in a bucket of clean water. Work the water over the entire surface, and use your brush to scrub as you rinse. For salt-heavy wood (especially ocean driftwood), consider soaking small to medium pieces in fresh water for 30 minutes to several hours. This allows the wood fibers to release salt deposits. If soaking, change the water once or twice during the process, as the water will become cloudy with salt and minerals.

After rinsing, scrub the wood with a brush and mild soap solution. Mix one or two teaspoons of dish soap in a bucket of water. Apply this solution with your brush, working in circular motions to lift stubborn residue. For algae growth or dark staining, make a paste of baking soda and water and scrub problem areas. White vinegar can also be sprayed on heavily stained sections and left for 10 to 15 minutes before scrubbing. Rinse thoroughly with clean water after each treatment to remove soap, vinegar, or baking soda residue.

Allow the driftwood to dry completely before moving or storing it. In warm, sunny weather, driftwood typically dries within 24 to 48 hours. Lean larger pieces against a fence or lay them on a clean surface where air can circulate around all sides. Smaller pieces can be placed upright in a bucket with drainage holes. Once dry, you may notice remaining discoloration or feel rough spots. This is normal and can be addressed with light sanding if desired.

Practical takeaway: Follow the sequence of dry brushing, water rinsing, soap scrubbing, and complete drying. This approach removes most salt, sand, and surface organisms effectively without damaging the wood.

Addressing Stubborn Stains and Deep Cleaning Challenges

Some driftwood pieces have deep staining, thick algae crusts, or mineral deposits that resist basic cleaning. These require additional treatment but can still be managed with household materials. For dark stains or algae that persists after soap scrubbing, oxygen-based bleach (such as OxiClean) offers an option that is less harsh than chlorine bleach. Mix oxygen-based bleach according to package directions and apply it to stained areas. Let it sit for 15 to 30 minutes, then scrub and rinse thoroughly. This method works without the strong smell and safety concerns of chlorine bleach.

Barnacles, shells, and other marine growth attached to ocean driftwood can be removed by gently chipping them away with a flat scraper or old knife. Work carefully to avoid gouging or splitting the underlying wood. Some barnacles may come off easily after soaking, while others require patient scraping. If you prefer to leave some shells or barnacles as part of the driftwood's character, simply clean around them with a brush.

For wood with soft spots, rot, or areas that feel spongy, assess whether the damage is surface-level or structural. Light surface rot can sometimes be lightly sanded away. Deep rot or hollow sections weaken the wood and may mean that piece is better suited for small decorative purposes rather than functional items. Press your fingernail or a small tool into suspicious soft areas; if it penetrates more than a quarter inch easily, the rot may be too extensive for indoor use.

If white mineral deposits or salt crystals return after drying, this indicates residual salt in the wood. A second soaking cycle, extended drying, and possibly a light brushing or sanding can help. Some driftwood pieces, especially those from saltwater environments, may always have a slight salty smell or slight whitish haze. This usually fades over time as the wood continues to dry and salt crystals diminish.

Practical takeaway: Oxygen-based bleach, patient scraping, and extended soaking address most stubborn problems. Know when to accept the wood's natural character rather than pursuing perfect appearance, and discard pieces with extensive rot.

Sanding and Finishing Your Cleaned Driftwood

After cleaning and drying, you may want to smooth the driftwood's surface. Light sanding creates a finished look, reduces splinters, and removes remaining discoloration. Start with 80-grit sandpaper for rough surfaces or heavy staining, progressing to 120-grit for general smooth
