Cleaning IPE Wood Deck

However, even a hardwood as tough as Ipe needs proper maintenance. Exposure to the elements—sun, rain, and dirt—means your deck will eventually show signs of wear. That’s why cleaning Ipe wood and protecting it with the right finish is key to preserving its colour and structural integrity.

Natural Weathering of Ipe

Over time, if left untreated, Ipe will naturally weather to a silvery-grey patina. This weathered look is popular in many commercial settings and coastal locations, but not every homeowner wants that. The good news is that weathering doesn’t weaken the wood—it only affects the surface appearance.

If you’d prefer to keep that rich brown hue, cleaning Ipe wood deck surfaces regularly and applying the right oil finish will help retain its natural charm.

Step-by-Step: Cleaning Ipe Wood Deck the Right Way

The first step to maintaining your deck is cleaning Ipe wood deck areas thoroughly. Debris like leaves and dirt trap moisture and can lead to surface issues over time. Here’s how to clean your deck properly using oxalic acid or a commercial deck cleaner.

1. Choose the Right Time

Avoid cleaning in direct sunlight. Early morning or evening is best so the cleaner doesn’t dry out too quickly.

2. Clear the Deck

Move all furniture and pots so you can access every board.

3. Safety First

Oxalic acid (also sold as Bar Keepers Friend) is very effective but should be handled carefully. Wear gloves, eye protection, and a mask.

4. Mix Your Cleaner

Follow the instructions on the package. Typically, ¼ to ½ cup of oxalic acid per gallon of warm water is sufficient.

5. Apply the Solution

Use a backpack sprayer or pump sprayer to apply the cleaner. Work in sections and keep the wood wet—drying reduces the effectiveness of the product.

6. Light Scrubbing (If Needed)

Use a stiff brush to scrub the deck lightly if dirt or stains are persistent.

7. Let it Soak

Leave the cleaner on the deck for about 10–15 minutes. Mist with a hose if it starts to dry out.

8. Rinse Well

Use a garden hose to rinse thoroughly. Make sure there’s no cleaner left behind.

9. Drying Time

Let the deck air dry completely before applying any finisher. This could take a few hours to a full day.

NOTE: After cleaning, your deck may appear lighter or bleached. Don’t worry—this is normal. Once you apply a finisher, the original colour will return.

10. Dispose of Waste Responsibly

Follow local guidelines for disposing of acid-based solutions.

Applying a Finisher: Protect and Enhance

After cleaning Ipe wood, applying a proper oil finish helps seal the surface, protect it from UV rays, and enrich its natural colour. At ABS Wood, we always recommend using a high-quality Ipe oil.

How to Apply Ipe Oil Finisher:

1. Prep the Surface – Ensure the deck is completely dry and clean.
2. Pick the Right Day – Choose clear, dry weather for at least 72 hours.
3. Stir, Don’t Shake – Mix the oil thoroughly before use.
4. Apply Evenly – Use a large synthetic brush with a broom handle to apply along the grain of each board.
5. Let It Soak – Allow 15–30 minutes for the oil to penetrate the wood.
6. Wipe Excess – If any oil pools, spread it or wipe it off. No puddling should be left.
7. Admire Your Deck – Once dry, your Ipe deck will have a rejuvenated, rich finish.

Ongoing Maintenance Tips for Ipe Decking

Maintaining your deck is about more than just seasonal cleaning. A regular routine will extend the lifespan and visual appeal of your investment.

1. Routine Cleaning

Regularly cleaning Ipe wood deck areas helps prevent mould and surface build-up. Sweep off leaves and use a mild detergent and water to clean up spills or grime. Avoid harsh chemicals or power washing, which can damage the fibres.

2. Annual Inspection

Check your decking once a year for any cracks, loose boards, or other signs of wear. Prompt repairs prevent larger problems down the line.

3. Reapply Oil Finisher

Depending on your environment, you may need to reapply your oil finish every 1 to 3 years. If the deck looks faded or dry, it’s time for a refresh.

4. Protect with Pads

Use furniture pads under heavy items to prevent scratching. While Ipe is incredibly tough, protective pads can prevent unnecessary surface wear.

5. Clear Surroundings

Keep plants trimmed back and remove debris from underneath the deck to allow airflow and prevent moisture build-up.

6. Watch for Standing Water

Make sure your deck is graded correctly so water doesn’t pool. If necessary, adjust landscaping or add drainage solutions.

7. Stick to a Maintenance Calendar

Mark your calendar for a yearly cleaning and finishing. This consistent care will keep your Ipe deck looking like new.
