Pressure washers are powerful tools designed to remove dirt, grime, and stains from various surfaces with a high-pressure stream of water. They are commonly used for tasks like cleaning driveways, patios, and vehicles. However, when it comes to cleaning delicate items like furniture, especially indoor or outdoor furniture, many people wonder if a pressure washer is an appropriate choice. This article will explore whether or not using a pressure washer for cleaning furniture is a good idea, what types of furniture can be safely cleaned with it, and the best techniques for using a pressure washer on furniture.
Understanding Pressure Washers
A pressure washer works by forcing water through a nozzle under high pressure. This stream of water is effective in removing dirt, stains, and debris from surfaces that are tough enough to withstand the pressure. Pressure washers are usually powered by either electricity or gas, and they can range from light-duty models to heavy-duty machines.
When it comes to cleaning furniture, the main concern is whether the pressure from the washer is too strong for delicate materials. Furniture, especially upholstered items or those made of wood, requires more careful attention compared to outdoor surfaces like concrete or brick.
Types of Pressure Washers
Before diving into the specifics of using a pressure washer on furniture, it’s important to consider the type of pressure washer being used. Electric pressure washers are typically lighter and offer lower pressure compared to gas-powered machines, which are more powerful and suited for large, tough cleaning jobs.
For cleaning furniture, especially delicate materials like wood or fabric, an electric pressure washer with adjustable settings is often the better option. Lower pressure settings will help prevent damage to the furniture, ensuring a thorough cleaning without compromising its integrity.
Types of Furniture That Can Be Cleaned With a Pressure Washer
Not all furniture is suitable for cleaning with a pressure washer. Some materials are too delicate or porous, while others are built to withstand the force of water pressure. Below, we explore which types of furniture can generally be cleaned with a pressure washer.
Outdoor Furniture
Outdoor furniture, especially items made from plastic, metal, or certain types of wood, can generally withstand pressure washing. These materials are more durable and less prone to damage from water. Here are some common types of outdoor furniture that can be cleaned with a pressure washer:
Plastic Furniture
Plastic furniture is one of the easiest to clean with a pressure washer. The high pressure will effectively remove dirt, stains, and grime from plastic surfaces without causing damage. For best results, use a low-pressure setting and a wide spray nozzle to ensure an even cleaning.
Metal Furniture
Metal furniture, especially aluminum and wrought iron, is also suitable for pressure washing. The pressure washer can clean rust, dirt, and any buildup from the surface. However, it’s essential to ensure the metal is properly dried afterward to prevent rust formation. For painted metal furniture, be cautious of using too high of a pressure setting, as it could chip the paint.
Wooden Furniture (Treated or Sealed)
Wooden outdoor furniture, if treated or sealed properly, can be cleaned with a pressure washer. Sealed wood is more resistant to water damage, making it safer for pressure washing. However, untreated or weathered wood may absorb too much water, which could cause swelling, warping, or even mold growth. If you choose to pressure wash wooden furniture, always use a lower pressure setting to avoid splintering the wood.
Upholstered Furniture
Upholstered furniture, including couches, chairs, and cushions, should generally not be cleaned with a pressure washer. The high-pressure water can damage the fabric or cause the stuffing to become waterlogged, leading to mold and mildew growth. If you’re dealing with outdoor cushions, it’s best to follow the manufacturer’s cleaning instructions, which usually recommend using a gentle detergent and a garden hose.
However, if the upholstery is made of a material like Sunbrella fabric, which is designed to withstand outdoor conditions, you might be able to use a pressure washer on a low setting. Always perform a spot test on an inconspicuous area before proceeding with pressure washing any upholstered furniture.
Fabric and Cushions
For cushions and fabric-based furniture, using a pressure washer is typically not recommended. The force of the water can penetrate the fabric and cause it to lose its shape or texture. It could also lead to mold growth if the cushion doesn’t dry quickly enough. Instead, clean fabric cushions with a gentle brush and mild detergent.
Techniques for Using a Pressure Washer on Furniture
If you’ve determined that your furniture is suitable for pressure washing, the next step is to know how to use the machine correctly. Here are some techniques to ensure you clean your furniture efficiently and safely.
1. Set the Right Pressure
The most crucial step in using a pressure washer on furniture is to adjust the pressure. Always use a low-pressure setting, especially for delicate materials like wood and metal. A high-pressure stream can damage the surface or cause splintering, chipping, or rusting.
Many pressure washers come with adjustable nozzles, so you can choose the appropriate spray pattern. Use a wide, gentle spray for large surfaces and a narrower spray for concentrated areas with stubborn stains. Always start at a distance and gradually move closer to test how the surface reacts to the pressure.
2. Use the Right Nozzle
The nozzle you use plays an important role in how the water is distributed. For cleaning furniture, it’s best to use a 25-degree or 40-degree nozzle. These nozzles offer a wider spray pattern, which distributes the pressure over a larger area, minimizing the risk of damage. Narrower nozzles should only be used for tougher areas where more focused cleaning is needed.
3. Keep the Right Distance
When using a pressure washer on furniture, always keep the nozzle at least 12 to 18 inches away from the surface you’re cleaning. Holding the nozzle too close can cause damage, especially to painted or treated wood surfaces. Maintaining the right distance ensures that the water pressure is spread evenly and reduces the chances of scarring or chipping the surface.
4. Move in a Steady Motion
To avoid concentrating water on one spot for too long, which could cause damage, always move the nozzle in a steady, sweeping motion. Work your way around the furniture, covering the surface thoroughly but quickly. This technique prevents water from being forced into cracks or crevices, which could lead to moisture buildup or wood swelling.
5. Dry the Furniture Properly
After pressure washing, make sure the furniture is properly dried. If you’re cleaning wooden furniture, wipe it down with a dry towel to remove excess water. For metal furniture, ensure the surfaces are fully dry to prevent rusting. Allow cushions and fabric to air dry in a well-ventilated area. Leaving furniture damp for extended periods can lead to mold, mildew, and other damage.
When to Avoid Using a Pressure Washer on Furniture
While pressure washers can be a powerful cleaning tool, they aren’t suitable for all types of furniture. In the following cases, it’s best to avoid using a pressure washer:
- Delicate wood furniture that has not been sealed or treated
- Upholstered furniture, especially indoor pieces
- Furniture with intricate details that might be damaged by the force of the water
- Furniture made of composite or fragile materials, which may not hold up to high pressure
Conclusion
Using a pressure washer to clean furniture can be an effective and efficient way to maintain your outdoor items, especially those made from durable materials like plastic, metal, and treated wood. However, caution is needed when dealing with more delicate materials like fabric and untreated wood. Always adjust the pressure settings, use the right nozzle, and keep the nozzle at an appropriate distance to avoid damaging the furniture.
When in doubt, it’s always a good idea to refer to the manufacturer’s cleaning instructions to ensure that you’re using the best method for your specific furniture type. With the right technique and the proper pressure settings, you can keep your furniture looking clean and fresh, extending its lifespan while maintaining its appearance.
