Maintaining the beauty and longevity of your Trex deck is crucial. Regular cleaning, especially pressure washing, is key to keeping it looking its best and preventing damage. However, improperly pressure washing Trex can lead to scratches and other issues. This comprehensive guide will walk you through the process safely and effectively.
Understanding Trex and Pressure Washing
Trex decking is a composite material, known for its durability and low-maintenance requirements. While relatively tough, it's still susceptible to damage from high-pressure water streams. The key is to use the right pressure and technique to clean effectively without causing harm.
Why Pressure Wash Your Trex Deck?
- Removes Dirt and Grime: Pressure washing effectively removes ingrained dirt, mildew, mold, and other debris that accumulate over time.
- Restores Appearance: A clean Trex deck looks significantly better, enhancing your home's curb appeal.
- Prevents Damage: Removing dirt and mildew prevents these substances from damaging the decking material over time.
- Maintains Warranty: Many Trex warranties require regular cleaning to remain valid.
Preparing for the Pressure Washing of Your Trex Deck
Before you even think about turning on the pressure washer, preparation is key. This step will ensure a smooth and efficient cleaning process.
Gathering Your Supplies:
- Pressure Washer: Choose a pressure washer with adjustable pressure settings. Avoid using a pressure washer with over 1500 PSI.
- Cleaning Solution: A Trex-approved cleaner is recommended. Avoid harsh chemicals that could damage the decking.
- Garden Hose: For rinsing and pre-cleaning.
- Cleaning Brushes (optional): For stubborn stains or mildew.
- Safety Gear: Eye protection and work gloves are essential.
- Extension wand (recommended): Allows you to reach higher areas with less strain.
Pre-Cleaning Your Trex Deck:
- Sweep or blow away loose debris: Remove leaves, twigs, and other loose material before pressure washing.
- Rinse the deck with a garden hose: This helps to remove surface dirt and loosen up embedded grime.
Pressure Washing Your Trex Deck: Step-by-Step Guide
Now for the main event! Remember, gentle is key. Too much pressure can damage your Trex deck.
- Set the pressure: Use the lowest pressure setting on your pressure washer. Start with a test area in an inconspicuous spot to ensure the pressure isn't too high.
- Apply cleaning solution: Follow the instructions on your chosen Trex cleaner. Apply the solution evenly across the deck surface.
- Pressure wash in sections: Work in small sections, overlapping slightly to ensure complete coverage. Use a sweeping motion, keeping the nozzle a few inches from the surface. Avoid holding the nozzle in one spot for too long.
- Rinse thoroughly: After washing each section, rinse thoroughly with a garden hose to remove all traces of the cleaning solution.
- Allow to dry: Let the deck dry completely before using it.
Post-Cleaning and Maintenance
Once your Trex deck is clean and dry, you're not quite finished. Here are some tips to keep it looking great:
- Regular cleaning: Pressure wash your Trex deck at least once a year, more often if necessary.
- Spot cleaning: Address spills and stains immediately to prevent them from setting.
- Protect from harsh elements: Use a Trex approved sealant for added protection.
Choosing the Right Pressure Washer for Trex
The pressure washer you use is critical. As mentioned, avoid high-pressure washers (over 1500 PSI). Look for a pressure washer with adjustable pressure settings and a variety of nozzles to give you the control you need. A lower PSI option with a wider fan nozzle will be much gentler on the Trex surface.
By following these steps and using the appropriate pressure washing techniques, you can keep your Trex deck looking beautiful for years to come. Remember, prevention is better than cure, so regular cleaning will save you a lot of effort in the long run!
