Cleaning IPE Wood Deck

Ipe Decking – cleaning and maintain that beautiful look

Ipe, also known as Brazilian Walnut or Ironwood, is a popular choice for decking due to its exceptional durability and natural beauty. Ipe is renowned for its hardness, density, and resistance to rot, decay, insects, and moisture. Its rich, dark brown color with hints of olive and reddish-brown hues adds elegance and sophistication to any outdoor space.  However, Ipe like any outdoor product needs periodic maintenance to look its best.

Natural Aging Process of Ipe

Ipe that has naturally grayed and needs cleaningLeft untreated, Ipe decking will naturally weather and turn a silvery-gray color over time when exposed to sunlight and the elements. This natural weathering is a popular choice in the islands, along the coast, on boardwalks, and frequently in commercial applications. This gray patina is a result of the wood’s natural oils rising to the surface and UV exposure. While this weathering process doesn’t compromise the structural integrity of the wood, some homeowners prefer to maintain the original color of their Ipe decking.

Maintaining the Ipe Colors  

First step is cleaning. Regular cleaning ipe wood is essential to keep your Ipe decking looking its best. Begin by removing debris such as leaves, dirt, and dust using a broom or leaf blower.

Next use oxalic acid deck cleaner (or commercial deck cleaner) to clean ipe wood which is an effective way to remove stains, discoloration, and other surface imperfections. Oxalic acid is a natural compound and is commonly used as a wood bleach and cleaning agent. You may have used it in your home as it is also known as “Barkeeper Friend.” Here’s a step-by-step guide on how to use oxalic acid deck cleaner (or commercial deck cleaner) to clean Ipe decking safely and effectively:

1. Timing:

Start in the evening or morning, avoid the full sun as it will dry out your cleaner greatly extending your time and efforts.

2. Prepare the Area:

Before beginning the cleaning process, remove any furniture, plants, or other objects from the cleaning ipe wood area. This will ensure that the entire surface is accessible and prevent any potential damage to surrounding items.

3. Protect Yourself:

Oxalic acid can be hazardous if not handled properly, so it’s essential to take proper safety precautions. Wear protective clothing, including gloves, goggles, and a mask, to avoid direct contact with the acid and fumes.  If you deck is outdoors you probably do not have to worry too much about fumes.

4. Dilute the Oxalic Acid:

Mix the oxalic acid crystals or powder with warm water according to the manufacturer’s instructions. Typically, you’ll use about 1/4 to 1/2 cup of oxalic acid concentrate per gallon of water, but be sure to follow the specific recommendations on the product label.

5. Apply the Solution:

Cleaner on the right side of the IpeUsing a pump sprayer apply the diluted oxalic acid solution evenly to the surface of the Ipe decking. We use a backpack pump sprayer. Work in small sections to ensure thorough coverage and avoid streaking or uneven application. You want to keep the surface wet. The cleaner does not work if the sun dries it out.

6. Scrub the Surface:

If necessary, after applying the oxalic acid solution, use a stiff-bristled brush to agitate the surface of the decking. This will help to loosen dirt, stains, and discoloration and allow the acid to penetrate more effectively.

7. Allow Time for the cleaner to work:

Let the oxalic acid solution sit on the decking surface for 10-15 minutes to allow it to work its magic. During this time, the acid will break down and dissolve stubborn stains and discoloration, making them easier to remove.  The cleaner needs to remain wet!  Keep a hose with a mister head to make sure your cleaner stays wet.

8. Rinse Thoroughly:

Once the dwell time has elapsed, thoroughly rinse the decking surface with clean water. Use a garden hose to remove any remaining oxalic acid solution and loosened debris. Be sure to rinse the decking thoroughly to prevent any residue from lingering on the surface.

9. Allow to Dry:

Finally, allow the Ipe decking to dry completely before applying any finisher or sealer. Depending on the weather conditions, this may take several hours to a full day. Once the decking is dry, you can proceed with sealing or finishing to protect and enhance its appearance.

10. Dispose of Waste Safely:

Dispose of any leftover oxalic acid solution and cleaning materials according to local regulations.

11. Questions:

If you’re unsure about using oxalic acid, deck cleaning in general, or dealing with particularly stubborn stains, consider calling ABSWood for assistance.

Applying Finisher to Ipe

Applying an Ipe oil finisher to Ipe decking is a crucial step in preserving its natural beauty and enhancing its longevity. Ipe oil finishers penetrate deep into the wood fibers, nourishing and protecting the decking from UV rays, moisture, and other environmental factors. Here are the steps for properly applying an Ipe oil finisher to Ipe decking:

1. Prepare the Surface:

Ensure that the decking is clean and free of any debris, dirt, or previous finishes. Sweep or blow away any loose particles, and thoroughly clean the surface with a mild detergent and water solution if necessary. Allow the decking to dry completely before proceeding.

2. Check the Weather:

When cleaning Ipe wood deck, choose a day with mild temperatures and low humidity for optimal results. Avoid applying the finisher in direct sunlight or on rainy or windy days, as this can affect the drying time and finish quality.  Look for 72 hours of clear weather!

3. Stir the Finisher:

Before opening the container, gently stir the Ipe oil finisher to ensure that any settled pigments or additives are evenly distributed throughout the product.

4. Apply the Finisher:

Using a high-quality synthetic brush apply the Ipe oil finisher evenly to the surface of the decking. (You want a large brush on a broomstick.  Check big box store in the broom aisle if you do not see it in the paint area.  You want to stand to apply.)  Work in small sections, applying finisher along the length of each board, following the direction of the grain.  There should be NO PUDDELING.  If you have puddling of the finisher use your brush to spread it to other boards.

5. Allow Penetration:

Allow the finisher to penetrate the wood for approximately 15-30 minutes, depending on the temperature and humidity levels. During this time, the finisher will soak into the wood fibers, nourishing and protecting the decking from within.

6. Wipe Off Excess:

If applied correctly, the finisher will soak in and there will be nothing left.  If you applied too much, use a clean, lint-free cloth or applicator pad to wipe off any excess finisher from the surface of the decking. This will help to prevent drips, streaks, and uneven application, ensuring a smooth and consistent finish.

7. Enjoy Your Newly Finished Decking:

Maintenance of Ipe Decking

Regular maintenance is key to prolonging the lifespan of your Ipe decking and avoiding Ipe wood problems. Inspect the deck annually for any signs of damage, such as cracks, splits, or loose boards, and make repairs as needed to prevent further deterioration. Keep the deck clear of debris and vegetation to allow for proper airflow and drainage. Depending on the climate and level of exposure, you may need to reapply a finisher every 1-3 years to maintain optimal protection and appearance.

1. Regular Cleaning Ipe wood deck:

1. • Sweep or blow away debris, leaves, and dirt from the surface of the decking regularly to prevent buildup.
   • Use a mild detergent and water solution to clean the decking surface periodically, especially in areas prone to stains or dirt buildup. Gently scrub with a soft-bristled brush or mop.
   • Avoid using harsh chemicals, abrasive cleaners, or pressure washers, as these can damage the wood fibers and finish.

2. Inspect for Damage:

1. • Conduct regular inspections of the decking to check for signs of damage, such as cracks, splits, or loose boards. Address any issues promptly to prevent further deterioration.
   • Pay attention to areas where water may pool or accumulate, as this can lead to mold over time. Ensure proper drainage and airflow to prevent moisture buildup.

3. Refinish as Needed:

1. • Monitor the appearance of the decking to determine when it needs to be refinished. Signs that refinishing may be necessary include fading, graying, or loss of water repellency.
   • If it looks good after the rain, but not on a sunny day, consider reapplying the finisher.

4. Protect from Furniture and Planters:

1. • Use furniture pads or feet protectors to prevent scratches, indentations, and other damage caused by heavy furniture or planters.  Light chairs and tables do not need these as Ipe is very hard.
   • Avoid dragging or sliding furniture across the decking surface, as this can cause scratches and abrasions.

5. Clear Vegetation and Debris:

1. • Keep the area around the decking clear of vegetation, leaves, and debris to prevent mold, mildew, and moisture buildup.
   • Trim overhanging branches or plants to allow for proper airflow and sunlight exposure.

6. Avoid Standing Water:

1. • Ensure that the decking surface is sloped slightly away from the house or structure to promote proper drainage and prevent standing water.
   • Address any areas where water may pool or accumulate, as this can lead to mold over time.

7. Annual Maintenance Routine:

1. • Establish an annual maintenance routine for your Ipe decking to ensure consistent care and preservation.
   • Schedule regular cleaning, inspection, and refinishing as needed to keep your decking looking its best year-round.

By following these steps and implementing a regular maintenance routine, you can effectively preserve the beauty, durability, and longevity of your Ipe decking for years to come. Proper maintenance will not only enhance the appearance of your decking but also protect your investment and ensure its continued enjoyment for outdoor living and entertaining.

Ipe decking offers unparalleled durability and beauty, making it an excellent choice for outdoor spaces. With proper care and maintenance, Ipe decking can provide decades of enjoyment for homeowners while retaining its natural charm and elegance.
