How to Clean WPC Decking? Can You Use a High-Pressure Water Gun?

Maintaining the appearance of WPC (Wood-Plastic Composite) flooring is key to keeping it beautiful and durable in the long term. Regular cleaning is especially important when these floors are exposed to outdoor environments. Many homeowners may ask, "How to clean WPC decking? Can I use a pressure washer?" This is a very natural question, as pressure washers are widely used to clean various outdoor surfaces. Below, we will explore the pros and cons of using a pressure washer to clean WPC decking flooring and other safer cleaning methods.

Risks of Cleaning WPC Decking Flooring

Using a pressure washer to clean WPC decking flooring can indeed lead to some issues. While a pressure washer can quickly remove dirt and stains, improper use may cause permanent damage to the flooring. Here are some problems that might arise with using a pressure washer to clean WPC decking flooring:

Deck Appearance Damage

If the pressure washer's settings are too high or the nozzle is too close to the floor surface, it may cause "etching" effects. This phenomenon can permanently damage the floor's appearance, stripping it of its original sheen.

Finish Damage

WPC decking flooring typically has a protective finish to guard against moisture and other environmental factors. If this finish is damaged, moisture can penetrate the flooring, leading to mold growth. This not only affects the floor's appearance but may also shorten its lifespan, increasing maintenance and replacement costs.

Higher Maintenance Costs

Due to potential damage from the pressure washer, repair work will become more complex and expensive, including dealing with mold and patching up damaged flooring.

Use the Lowest Pressure Setting

Always set the pressure washer to the lowest pressure. Follow the manufacturer's pressure recommendations, if available, to avoid unnecessary harm to the floor.

Adjust the Nozzle Angle

Ensure the nozzle is adjusted to the widest spray pattern to reduce direct impact on the floor.

Maintain Appropriate Distance

Keep a distance of at least 12 inches between the nozzle and the floor surface to avoid excessive impact and damage to the floor surface.

Perform a Test

Before thorough cleaning, do a small test in an inconspicuous area of the floor. Even during testing, follow the safety guidelines mentioned above to prevent floor damage.
