What is Power Washing?

Power washing refers to using high-pressure water to clean stubborn dirt, mold, grime, and other residues from surfaces. While pressure washers can seem like an easy solution to most cleaning jobs, they are recommended only for outdoor surfaces due to their power.

These machines are specifically designed to tackle the elements exposed to outdoor surfaces, such as sun-baked patios or mildew-infested sidings, and can restore these areas efficiently. 

Their power requires careful handling to prevent damage. So, when considering using a pressure washer, it is best suited for cleaning your siding, driveway, deck, and other hardy outdoor locations that can handle aggressive cleaning.

Can You Use a Pressure Washer Inside?

Using a pressure washer to clean the exterior of your home is a great idea, but it’s not safe to use it inside. The force of the water can damage your personal belongings and interior surfaces. Here are the major risks:

Water Damage and Mold Expansion

Power washing with high-pressure water indoors can cause significant water damage, even in hidden, hard-to-reach areas, such as beneath the flooring. This can create a perfect breeding ground for mold and mildew, especially in areas with wooden structures or drywall. The consequences can be aesthetic damage, the weakening of the building’s structure, and increased health hazards due to mold spores in the air. This is especially dangerous for homes that are prone to moisture issues. 

Increased Electrical Hazards 

The combination of water and electricity inside a home is a heightened risk when using power washing. This method can force water into electrical outlets, wiring, and appliances, increasing the risk of short circuits. This can lead to serious electrical fires or electrocution. 

Furniture Damage

High-pressure water can easily damage household furnishings. Surfaces not designed to withstand such pressure, including delicate wood finishes, paint, and other materials, can suffer from erosion, water ingress, and functional failure. 

Health Risks from Contaminants

Indoor power washing can cause mold spores and other contaminants, such as lead-based paints or asbestos, to become airborne, especially in older homes. These hazardous materials can become airborne when disturbed by the force of water, posing significant health risks to inhabitants through inhalation or direct contact.

Pressure Washing Can Do Wonders for Your House’s Exterior

Pressure washing can work wonders for the exterior of your house. It efficiently removes tough stains, mold, and mildew build-up, a significant problem in humid climates. Regular pressure washing can also prevent long-term damage to your home’s structure and aesthetics. 

From your siding, deck, or driveway, a power washer can breathe new life into every corner, enhancing your home’s curb appeal and potentially increasing its value. Using a pressure washer can also help protect your family’s health by keeping harmful mildew and pollutants at bay. 

The numerous benefits of power washing make it an indispensable aspect of external home care.

How a Pressure Washer Works

Pressure washers are highly effective at cleaning tough substances from surfaces that ordinary methods can’t reach. They work by amplifying a normal water supply into a high-pressure stream.

This is achieved through a hefty pump, a high-pressure hose, and a sturdy cleaning attachment. When connected to a water source, the machine propels water at pressures up to several thousand pounds per square inch, which is a lot more powerful than the gentle flow from a typical garden hose. 

This immense cleaning capability makes pressure washing particularly useful for cleaning the exterior of your house.

Proper Gear and Techniques for Power Washing

Protective gear and proper techniques are paramount when handling a pressure washer to avoid potential injury or damage to your property.

Basic Safety Gear for DIY Power Washing

Safety should be your top priority. Always wear protective gear, including goggles, gloves, long-sleeved shirts and pants, and close-toed, sturdy shoes to protect your skin from debris and prevent injury​​.

Equipment Selection

Choose a pressure washer that matches the material of the surface you are cleaning. Consider factors such as water pressure, flow rate, and nozzle types. Different surfaces may require different pressure settings and nozzles to avoid damage while ensuring a thorough cleaning​​.

Techniques for Effective Power Washing

Prepare the Area 

Clear the area of furniture, decorations, and any other items that the water pressure could damage. Cover delicate plants and electrical outlets to protect them during the cleaning process​​.

Using the Right Pressure and Nozzle

Start with the lowest pressure setting and gradually increase it as needed. Maintain a consistent distance from the surface, typically around 6-12 inches, to avoid damaging it. Use sweeping strokes and adjust the pressure according to the type of surface you’re cleaning​​​​.

Cleaning Solutions

Depending on the dirt type and surface, you may need specific cleaning solutions or detergents compatible with your pressure washer. Be sure to use only the recommended cleaning agents to avoid damaging the surface or the machine​​.


Practice with your pressure washer on a small, inconspicuous area before tackling the entire surface. Keep the nozzle safe from the surface and use sweeping motions to ensure even cleaning without damaging the material​​. By understanding and respecting the machine’s power, and donning appropriate safety gear, you protect your home’s exterior and well-being while undertaking any washing jobs.
