Pressure washing can be a game-changer when it comes to maintaining your home’s curb appeal. It’s an effective way to remove dirt, grime, mold, and algae from surfaces like driveways, decks, sidewalks, and siding. However, as simple as it may seem, pressure washing requires proper technique and equipment to avoid costly mistakes.
According to home maintenance experts, improperly used pressure washers can cause damages costing homeowners up to $2,000 in repairs. Additionally, the CDC reports that home improvement projects, including pressure washing, contribute to approximately 2 million injuries annually.
Here’s a guide to DIY pressure washing, the most common errors people make, and how AAA Pressure Washing can help you achieve professional results.
Most Common Mistakes in DIY Pressure Washing
Using the Wrong Pressure Setting
Pressure washers typically range from 1,300 to 4,000 PSI (pounds per square inch). Choosing the wrong pressure can lead to surface damage. For instance, using high pressure on wood can strip paint or gouge the material, while low pressure may not effectively clean concrete.
What to Do Instead: Use the appropriate pressure setting for each surface. Soft surfaces like wood and siding require lower PSI, while harder surfaces like driveways can handle higher pressure. Refer to your machine’s manual for guidance, and always test on a small, inconspicuous area first.
Skipping Pre-Treatment
Many people begin pressure washing without applying a cleaning solution. This oversight can leave stains and organic growth like mold and mildew partially intact. For example, trying to clean a moldy deck with just water can result in uneven cleaning and recurring growth.
What to Do Instead: Apply a detergent or cleaning solution suitable for the surface you’re washing. Let it sit for a few minutes to break down grime before rinsing with the pressure washer. Use biodegradable detergents for an eco-friendly approach. Professional pressure washing companies often use pre-treatment solutions like detergents for dirt and grime, mold removers for organic growth, degreasers for oil stains, and rust removers for unsightly discoloration.
Incorrect Nozzle Selection
Pressure washer nozzles come in different angles, ranging from 0° to 40°. A narrow-angle nozzle delivers concentrated power, which can damage surfaces, while a wider-angle nozzle provides a gentler spray. Imagine using a 0° nozzle on a painted wooden fence—the result could be peeling paint or deep scratches.
What to Do Instead: Use the correct nozzle for the task. For example, a 25° or 40° nozzle is ideal for general cleaning, while a 0° nozzle should be reserved for tough stains on hard surfaces. Keep the nozzle moving and maintain an appropriate distance to prevent damage.
Washing in the Wrong Direction
Cleaning in random patterns can leave streaks and uneven results. This often happens when tackling large areas like driveways or siding without a clear plan.
What to Do Instead: Work in smooth, overlapping passes from top to bottom or left to right. This ensures consistent cleaning and prevents streaking. For vertical surfaces, always start from the top and work your way down to avoid dirt running over already-cleaned areas.
Ignoring Safety Precautions
Pressure washers are powerful tools that can cause injuries. The high-pressure spray can cut through skin, and improper use can lead to slips, falls, or property damage. For instance, attempting to clean a high roof without proper footing can result in a dangerous fall.
What to Do Instead: Wear protective gear such as safety goggles, gloves, and closed-toe shoes. Avoid pointing the spray at yourself, others, or delicate surfaces. If cleaning elevated areas, use a stable ladder or consider hiring professionals for safety.
Underestimating Equipment Complexity
Many DIYers rent pressure washers without fully understanding how to operate them. Misuse can lead to damaged surfaces or even broken equipment. For instance, failing to release built-up pressure before disconnecting the hose can result in sudden bursts of water.
What to Do Instead: Familiarize yourself with the equipment by reading the manual or watching instructional videos. Take the time to learn how to adjust pressure settings, use nozzles, and safely operate the machine.
