Keeping your deck in pristine condition isn’t just about aesthetics. It’s about protecting your home and investment. Whether you’re preparing for summer BBQs or just want to boost curb appeal, deck cleaning is a task no homeowner should ignore. Over time, decks accumulate dirt, mold, algae, and stains that can cause long-term damage if left untreated.
In this guide, we’ll share practical and effective deck cleaning tips that every homeowner should know. From routine maintenance to when to call in professional help, these insights will help you preserve your deck’s beauty and safety.
Why Deck Cleaning Matters
Your deck is exposed to harsh elements year-round including rain, UV rays, foot traffic, and organic buildup. Without regular care, these factors can cause wood rot, warping, or discoloration. Routine deck cleaning prevents this damage, extending the life of your deck and keeping it safe for your family.
Clean decks also improve your property’s overall appearance. Whether you’re hosting guests or planning to sell your home, a fresh-looking deck can make a huge difference.

Choose the Right Cleaning Products
Not all decks are created equal. Wood decks, composite decks, and vinyl decks each require different cleaning approaches. Using the wrong cleaner can strip the finish or cause staining.
For wood decks:
- Use a wood-safe cleaner.
- Avoid bleach, which can damage wood fibers.
- Opt for oxygenated cleaners that remove stains and mildew gently.
For composite decks:
- Use non-abrasive cleaners.
- Avoid harsh chemicals like chlorine bleach or acetone.
Pro Tip:
Always test the cleaner on a small hidden area before applying it to the entire deck.
-
Sweep and Rinse Regularly
This may seem simple, but regular sweeping is one of the easiest ways to prevent buildup. Fallen leaves, dirt, and debris can trap moisture, encouraging mold growth. Use a broom to sweep off debris weekly, especially after storms or heavy winds.
Before any deep cleaning, rinse your deck with a garden hose or low-pressure washer to loosen grime and remove surface-level dirt.
-
Pressure Washing: Use with Caution
Pressure washing can be very effective for deck cleaning, but it must be done correctly. Too much pressure can damage the wood or cause splintering.
Tips for safe pressure washing:
- Use a fan-tip nozzle.
- Keep the pressure under 1500 PSI for wood decks.
- Maintain a safe distance (12–18 inches) from the surface.
If you’re unsure or uncomfortable handling a pressure washer, consider hiring a professional. Many homeowners in Louisiana rely on deck cleaning services in Jefferson Parish, LA for safe, effective results.
-
Schedule a Deep Clean Seasonally
While light cleaning can be done anytime, deep deck cleaning should be performed at least twice a year. Ideally in spring and fall. This seasonal approach helps remove buildup and prepare your deck for temperature changes.
Deep cleaning involves:
- Scrubbing with a soft-bristle brush
- Using a biodegradable deck cleaner
- Rinsing thoroughly to avoid residue
-
Inspect for Mold, Mildew, and Damage
Decks are vulnerable to mold and mildew, especially in humid areas like Jefferson Parish, LA. Check for dark spots, greenish patches, or a musty smell. These are signs that your deck needs a deeper clean or possible repair.
If mold returns quickly after cleaning, your deck may have drainage or sealing issues. In that case, it’s wise to call in professionals for a full inspection.
-
Seal and Protect Your Deck
Cleaning your deck is only half the battle. Sealing protects the wood from moisture, UV rays, and wear. After your deck is clean and dry, apply a high-quality deck sealer or stain.
Sealing Tips:
- Only apply sealer on a completely dry deck.
- Use a roller or sprayer for even application.
- Reapply every 1–2 years, depending on weather exposure.
When to Call Professional Deck Cleaners
While DIY deck cleaning works for many homeowners, some situations call for expert help. If your deck has:
- Deep-set stains
- Mold or algae you can’t remove
- Loose boards or nails
- A large surface area
… then hiring deck cleaning services in Jefferson Parish, LA can save you time, effort, and long-term repair costs.
Professional companies like Blizzard Pressure Washing LLC use specialized tools and eco-friendly cleaners that safely restore your deck without damage.
FAQs
- How often should I clean my deck?
It’s recommended to clean your deck at least twice a year. Once in spring and once in fall. However, regular sweeping and rinsing should be done weekly to prevent buildup.
- Can I use a pressure washer on my wood deck?
Yes, but use low pressure (under 1500 PSI) and a fan-tip nozzle. Too much pressure can damage wood fibers and cause splintering.
- What’s the best cleaner for mold on decks?
Oxygenated cleaners are best for mold and mildew. Avoid bleach-based products, especially on wood, as they can damage the surface and surrounding plants.

Wait 24–48 hours for the deck to fully dry before applying any sealer. Moisture trapped under the sealant can lead to peeling or mildew.
