Cleaning an Ipe Deck is Easier Than You Think

Ipe (pronounced “EE-pay”) is a beautiful and incredibly durable tropical hardwood, prized for its natural resistance to rot, decay, and pests. Often called Brazilian walnut, its rich, dark brown color with reddish-gold hues makes it a stunning choice for any outdoor space.

While it’s one of the toughest woods in the world, a properly maintained ipe deck still needs attention to retain its beauty and longevity. This guide will walk you through

Understanding Ipe Wood

Before you begin cleaning ipe wood, it’s helpful to understand what makes it unique. Ipe is exceptionally dense and naturally contains oils that provide a built-in defense against moisture and insects.

Left untreated, ipe will weather to an elegant silver-gray patina over time. Many homeowners prefer this aged look, but if you want to preserve the wood’s original rich color, a regular regimen of cleaning and oiling is essential.

With proper care, an ipe deck can last for 25 to 50 years or more. When you’re considering materials and how long a deck should last, it’s clear that ipe is a top-tier choice.

Regular Maintenance for your Ipe Deck

Routine care is your best defense against dirt buildup and weathering. Regular sweeping to remove leaves and debris prevents trapped moisture that can lead to mold and mildew. A simple hose-down can also go a long way in keeping your deck looking good between deep cleans.

For seasonal maintenance, a proactive approach can make your annual cleaning much easier. In the fall, ensure all leaves and debris are cleared to prevent moisture from sitting on the surface over the winter. In the spring, give the deck a thorough inspection for any signs of wear and tear, and prepare for a deep clean.

A key part of this process is avoiding common maintenance mistakes:

• Do not use harsh household bleach, as it can strip the wood of its natural oils and damage the fibers.
• Avoid cleaners with sodium hydroxide unless you’re confident in your ability to neutralize the wood afterward.

Deep Cleaning Your Ipe Wood Deck

This is the most critical step to revitalize your deck. The goal is to remove dirt, grime, and any graying caused by UV exposure without damaging the wood.

1. Preparing Your Deck for a Deep Clean

Start by clearing the deck of all furniture, planters, and other items. Sweep the entire surface with a broom to remove loose debris, paying close attention to the gaps between boards where dirt often accumulates.

If you notice any stubborn spots or stains, these may require specific treatment. Inspect the wood for any loose screws or splintered boards and address them before cleaning.

2. Choosing the Right Cleaning Products

Selecting the right product is key for a successful ipe wood deck cleaning.

Oxygenated cleaners, like those containing sodium percarbonate (the active ingredient in products like OxiClean), are highly recommended. These products lift dirt and grime to the surface and are effective at addressing mold and mildew.

Another popular choice is a deck cleaner and brightener system. The cleaner lifts dirt, and the brightener, which often contains oxalic acid, restores the wood’s natural color and neutralizes the cleaner.

For more stubborn stains like oil or grease, a powerful degreaser like Trisodium Phosphate (TSP) can be used, though it’s important to use it with caution and ensure a thorough rinse. SamaN TSP Eco is your best bet.

3. Safe Cleaning Techniques

Begin by applying your chosen cleaning solution to a small, inconspicuous area to ensure it doesn’t negatively affect the wood. When you’re ready to proceed, apply the cleaner evenly across the deck using a natural bristle brush, a soft mop, or a garden sprayer. Scrub in the direction of the wood grain to avoid scratching the surface.

Let the solution sit for the recommended time (usually 10-15 minutes), ensuring it does not dry on the surface. Afterward, rinse the deck thoroughly with a garden hose until all residue is gone.

4. Pressure Washing: How to Do It Right and Common Pitfalls

While many professionals use pressure washers, they can easily damage the wood if used incorrectly. The best way to clean an ipe deck with a pressure washer is to use a low-pressure setting, no more than 1200 psi.

Always use a fan-tip nozzle and keep it at a consistent, safe distance (at least 12-18 inches) from the deck surface.

A pressure washer can be an effective tool, but we do not recommend it for a novice, as it can splinter the wood and ruin the finish. A gentler approach with a soft-bristle brush and a garden hose is a safer alternative.

5. Protecting and Sealing Your Ipe Deck

After you clean the ipe deck, you have two options: let it naturally gray or protect it with an oil-based finish. If you want to preserve the rich, beautiful color of your deck, applying an oil as a sealant is essential.

6. When and Why to Seal Your Deck

Once your deck is completely dry, which can take 24 to 48 hours depending on the climate, it’s time for the ipe wood treatment. The purpose of this step is to protect the wood from UV rays and moisture.

A high-quality oil-based finish formulated for hardwoods with a UV inhibitor will provide the best protection and enhance the wood’s color. A good example is DeckWise’s Ipe Oil.

7. Applying the Finish

Using a brush, roller, or sprayer, apply a thin, even coat of the oil to the deck surface. It’s better to apply too little than too much, as ipe’s density means it won’t absorb a lot of product.

Let the oil penetrate the wood for about 15-30 minutes, then use a clean cloth to wipe off any excess. This is a critical step; leaving excess oil on the surface can result in a sticky, “gunky” deck.

8. Restoring an Aged or Weathered Ipe Deck

If your deck has already turned gray or has heavy stains, a more intensive refinishing ipe deck process may be needed.

9. Sanding Your Ipe Deck: Techniques and Purpose

After a deep cleaning and brightening, the best way to sand a deck is with a power sander and 60- to 80-grit sandpaper. Sanding will remove the top layer of weathered wood and any remaining surface imperfections, revealing the beautiful, rich wood underneath.

Always sand with the grain of the wood to avoid unsightly marks and scratches. Afterward, rinse away all dust and allow the deck to dry completely before applying a new coat of oil.

Conclusion

Proper ipe deck maintenance is a simple process that pays off with a lifetime of beauty and enjoyment. By following these steps for cleaning ipe decking, you can protect your investment and ensure your outdoor space remains a stunning focal point for decades to come. Whether you prefer the natural gray patina or the rich brown of a freshly oiled deck, a regular regimen of ipe wood care will help you get the most out of this remarkable material.
