Why Your Deck Needs Regular Cleaning in Vancouver, BC

Vancouver’s climate brings a lot of rain and mild temperatures.

1. This weather is perfect for mold, mildew, and algae to grow on outdoor surfaces. Think of it as a constant spa day for unwanted green stuff!

Over time, this growth, along with dirt and pollen, can make your deck look dull, discolored, and even slippery. A slippery deck isn’t just ugly; it can be dangerous too. Taking care of your deck regularly isn’t just about making it look nice. It’s about keeping your deck strong and making it last longer.

2. If you don’t clean away the moisture and growth, your deck can start to rot. This means expensive repairs later on. A good wood deck wash is key to stopping these problems.

3. It also keeps your outdoor space safe and welcoming for everyone.

What’s Your Deck Made Of: Wood or Composite?

Before you pick a deck washing solution, it’s super important to know what your deck is made from. What works great for a wood deck is often different from what works best for a composite one.

• Wood Decking: Traditional wood decks, like those made of cedar or treated pine, need careful cleaning so they don’t get damaged. Wood can soak up water easily. This leads to mold, mildew, and graying from the sun.
• Composite Decking: Composite decks, made from wood fibers and plastic, are known for being easy to care for. But they can still get dirty and moldy, especially in the textured parts that look like wood. Strong chemicals can sometimes change the color or harm composite surfaces. So, picking the right deck cleaner is very important

The Best Deck Washing Solutions for BC Decks

When it comes to good deck cleaners, especially in Vancouver, BC’s wet conditions, some solutions work better and are safer.

Sodium Percarbonate

For most deck cleaning jobs, like removing dirt, grime, mold, and mildew, sodium percarbonate is usually the top choice. This cleaner uses oxygen and comes as a powder. When you mix it with warm water, it creates hydrogen peroxide and sodium carbonate.

• Good points: It’s great at removing organic stains, mold, and mildew. It won’t hurt your wood or composite deck. Unlike chlorine bleach, it doesn’t strip the natural color from wood. It’s also safer for plants and the environment. Plus, it works as an excellent wood brightener, making old, weathered wood look fresh and new.
• Things to consider: For very deep stains, you might need to scrub a bit more than with stronger cleaners. You often need to use a wood brightener afterward to bring back the wood’s full color.

Why You Should Skip Chlorine Bleach for Deck Washing

You might think chlorine bleach is a quick fix for tough stains, but we generally don’t suggest it for cleaning decks, especially wood ones.

• Good points: It does kill mold and mildew well.
• Things to consider: Chlorine bleach can permanently damage wood fibers. This can make the wood feel rough or splintery. It can also strip the natural color from wood, making it lighter in uneven spots. It can even make the wood more likely to get damaged later. For composite decks, bleach can cause discoloration, stains, or even weaken the material over time. It’s also bad for nearby plants and can harm animals in water if it runs into drains.

What a Wood Brightener Does

After cleaning a wood deck, especially with sodium percarbonate, using a wood brightener is a crucial next step. These products usually have oxalic acid or phosphoric acid in them.

• What it does: A brightener balances the wood’s pH after cleaning. More importantly, it brings back the wood’s natural color, undoing the graying caused by the sun and the slight darkening from oxygen cleaners. It also helps remove dark spots from leaves or rust and gets the deck ready for sealing or staining.

How to Clean Your Deck: Step-by-Step

No matter which cleaner you choose, using it the right way is key to getting the best results and protecting your deck.

1. Get Ready: Take all furniture, planters, and clutter off your deck. Sweep it well to get rid of loose dirt and leaves. Cover nearby plants with tarps if you need to.
2. Wet the Deck: Lightly wet the whole deck surface with a hose. This helps the cleaner spread evenly and stops it from drying too fast.
3. Put on the Cleaner:-
   1. For Sodium Percarbonate: Mix it as directed on the package, usually with warm water. Apply it with a sprayer, roller, or stiff brush.
   2. For Composite Deck Cleaners: Follow the instructions on the product.
4. Let it Sit: Let the cleaning solution stay on the deck for the time suggested (usually 10-20 minutes). Don’t let it dry. If it starts to dry, mist it lightly with water.
5. Scrub (Gently!): Use a stiff brush (not a wire brush, which can damage wood or composite) to scrub the deck surface. Work with the grain of the wood or composite boards. Pay extra attention to very dirty or stained areas. For a powerful wood deck wash, you can use a pressure washer, but be super careful. Use a wide tip (40-degree or wider) and keep it at least 8-12 inches away from the surface. This helps avoid making marks or damaging the material. Lower pressure is always better, especially on older wood or softer composites.
6. Rinse Thoroughly: Rinse the entire deck very well with a garden hose or a low-pressure setting on your pressure washer. Make sure all the cleaner is washed away.
7. Apply Wood Brightener (for wood decks): If you cleaned a wood deck, put on a wood brightener right after rinsing the cleaner. Follow the product’s directions. Let it sit, then rinse well. This step is crucial for making the wood look vibrant again and getting it ready for sealing.
8. Let it Dry: Let your deck dry completely. This usually takes 24-48 hours. Then you can put on any sealer or stain.

Fixing Specific Stains in BC

• Mold and Mildew: These are common in Vancouver and are best cleaned with sodium percarbonate cleaners.
• Rust Stains: Wood brighteners with oxalic acid are great at removing rust stains from wood.
• Grease and Oil: For tough grease or oil spots, you might need a degreaser or a stronger, special deck cleaner. Always rinse well afterward. And always test in a hidden spot first!
