Known for its incredible durability and striking natural beauty, IPE wood is one of the most sought-after materials for premium outdoor decks. But despite its resilience, IPE is not maintenance-free. Even the finest hardwood needs the right care to keep it looking its best year after year. Unfortunately, many homeowners unknowingly make critical errors when it comes to cleaning their IPE decks—mistakes that can damage the wood, shorten its lifespan, or mar its appearance.
If you want to protect your investment and enjoy your deck’s natural elegance for decades, understanding what not to do is just as important as knowing the right techniques. In this guide, we’ll explore common IPE deck cleaning mistakes and share expert tips to help you avoid them.
Whether you’re taking the DIY route or hiring professionals for IPE deck wood cleaning, these insights will set you up for success.
Using Harsh Chemical Cleaners
One of the biggest missteps homeowners make is using strong chemical cleaners designed for other types of decking or general-purpose cleaning. IPE is dense and oily, and the wrong product can strip away its natural oils, discolour the surface, or cause long-term damage.
Avoid chlorine bleach, harsh acids, or cleaners not specifically formulated for hardwood decks. Instead, choose a pH-balanced cleaner that is safe for IPE, or opt for oxygenated wood cleaners designed to gently lift dirt without harming the wood’s structure or finish.

Skipping Routine Cleaning
Another common mistake is only cleaning the deck when it starts to look dirty. While IPE is highly rot- and insect-resistant, it can still accumulate grime, pollen, mould, and mildew, especially in shaded or damp environments.
Experts recommend a light cleaning at least once or twice a year—typically in the spring and again in the fall—to prevent buildup. This keeps your deck safe to walk on, looking its best, and helps to extend the life of the finish.
Overusing High-Pressure Washers
Many people turn to pressure washers as a quick solution to clean their decks, but with IPE, using too much pressure can do more harm than good. High-pressure water can gouge the surface, raise the grain, and even strip out natural oils.
If you do use a pressure washer, always:
- Use a wide-fan tip
- Keep pressure under 1,200 PSI
- Maintain a safe distance (at least 12–16 inches from the surface)
For safer results, many pros recommend soft washing with gentle cleaners instead.
Neglecting to Pre-Wet the Deck
Cleaning solutions—even mild ones—can soak into dry wood unevenly, which can cause blotchy staining or dark spots on IPE. A simple but often overlooked step is to pre-wet the entire deck with clean water before applying the cleaner.
This saturates the wood’s surface just enough to ensure even absorption and helps prevent staining or discolouration.
Cleaning in Full Sunlight
Timing matters when cleaning an IPE deck. Applying cleaning products in full sun, on a hot day, can cause the solution to dry too quickly—before it has time to work effectively. This can leave streaks or cause uneven results.
It’s best to clean your deck on an overcast day or during the early morning or late afternoon when the sun is less intense. Work in small sections to maintain control.
Failing to Rinse Thoroughly
One of the simplest but most common mistakes is not rinsing the deck thoroughly after cleaning. Residual soap or cleaner can leave a sticky film that attracts dirt, interfere with sealants or oils, or cause streaking.
Use plenty of clean water and rinse until runoff is completely clear. Pay extra attention to any grooves or joints between boards.
Skipping Regular Maintenance Oil
While cleaning removes dirt and contaminants, IPE also benefits from the occasional application of high-quality deck oil. This helps replenish the wood’s natural oils, maintains its rich colour, and protects against UV rays and moisture.
Failing to oil your deck (especially after a deep cleaning) can lead to faster fading, weathering, and cracking. Depending on sun exposure, most experts suggest oiling IPE once every 12–18 months.

Using the Wrong Tools
Lastly, using the wrong brushes or tools can damage the surface. Avoid stiff wire brushes, steel wool, or abrasive pads. These can scratch and scar the wood’s smooth finish.
Instead, use soft-bristled brushes or synthetic deck scrubbers designed for hardwoods. A simple garden hose with a spray nozzle is often sufficient for light cleaning between deep cleans.
Keeping an IPE deck looking beautiful requires a mindful approach. By avoiding these common mistakes and following expert tips, you’ll preserve your deck’s natural beauty, enhance its durability, and continue to enjoy it season after season.
