Clean Gutters with a Pressure Washer

Soffits and gutters can be some of the most difficult areas of a home to keep clean. However, using a pressure washer makes it easy to maintain these hard-to-reach places. The following sections cover which accessories can help and discuss tips for safe and effective pressure washing to get soffits and gutters looking like new. 

Step 1. Wet Soffits and Surrounding Foliage 

Tough stains require detergent for a thorough clean; however, before applying soap, the entire area should be soaked with clean water. This prevents damage to surrounding foliage while rinsing away large debris or dirt from the soffits, allowing the detergent to work more effectively. 

A low-pressure nozzle should be used for the initial rinse to avoid damaging plants or propelling debris into the soffits. During this step, the outsides of the gutters should also be rinsed clean. 

Step 2. Apply Detergent 

The detergent tank or pail should be filled with a detergent solution. If using a concentrated formula, it must be diluted according to the instructions on the container. With the detergent tank switched to "On" and the soap spray tip attached, the detergent can be applied to the soffits and the outside of the gutters. 

The user should not face the soffits directly; instead, aim ahead and slightly to the side. This technique ensures that any blown detergent water moves away from the operator. Spraying directly upward at the soffits should be avoided to prevent excessive water from being propelled into the structure. Minimizing the amount of water inside soffits is crucial, as moisture buildup can lead to mold or mildew growth. Once the surfaces are covered, the detergent should be allowed to work the dirt loose while the spray nozzles are switched. 

Step 3. Spray Dirt & Detergent Away 

While the detergent works on the stains, the nozzle should be switched to a high-pressure spray pattern. The detergent tank must be turned "Off," and the nozzle should be aimed at a walkway while the trigger is squeezed to flush out any remaining soap from the line. 

Rinsing should begin at the same spot where the detergent was first applied, working in the same direction. The user should spray evenly along the soffits and gutters to remove all detergent, dirt, and stains. Stubborn spots may require additional time to ensure an even clean. Once finished, the user should switch back to a low-pressure nozzle to spray clean water over the surrounding foliage, rinsing any remaining residue. 

Step 4. Clean Inside the Gutters 

While it may be tempting to climb a ladder to clean the inside of a gutter, it is much safer to use a method that keeps both feet on the ground. Using a pressure washer from a ladder should be avoided whenever possible. 

Instead, a power washer gutter cleaner attachment can be used. These curved tools allow the wand to be held up to spray directly into the gutters from the ground. The process should start near a downspout, spraying away from it. By angling the wand so the stream points away from the downspout and progressing down the length of the gutter, the force of the water will propel debris out.  

To avoid clogs, care should be taken not to force too much debris into the downspouts; if gutters are heavily filled, manual cleaning of the largest debris may be necessary first. 

Telescoping Wand 

This is a must-have tool for houses that are two stories or taller. The high-pressure hose connects directly to the telescoping wand, which can be extended by 12, 18, or 24 feet. A 12-foot fiberglass wand is generally ideal for residential use. 

Gutter Cleaning Wand 

This U-shaped gutter cleaner wand connects to the end of the telescoping wand. By placing it inside the gutters at an angle, the high-pressure spray can blast away leaves in seconds. Additionally, the wastewater helps clear the downspouts. 

The primary downside is that the operator will likely get dirty and wet, as both rain and pressure washer spray fall downward. Before starting, put on protective eyewear and a hat. 

Sweep Washing the Fallen Mess 

Once leaves and other debris are cleared from the gutters, they will likely litter the walkways and patios where they landed. The best way to clean up the resulting mess is with a water broom. These accessories sweep away debris while giving walkways, decking, and patios a fresh, clean look. It is important to choose a water broom that is compatible with the specific pressure washer being used. 

If a pressure washer produces at least 2.3 GPM and 2,700 PSI, it can be equipped with a TriKleener Deluxe professional water broom, which features three nozzles for cleaning a wider area. 

However, if a pressure washer produces less than 2.3 GPM and 2,700 PSI, a BiKleener water broom with two nozzles is a better option. The lower PSI will clean more effectively when distributed through two nozzles instead of three. While the cleaning width is 10" to 12" rather than 14", it is more effective for units with lower GPM and PSI. A minimum of 1.2 GPM and 1,500 PSI is still required, but most pressure washers meet these specifications.
