Pressure Washer Maintenance Tips: How to Extend the Life of Your Equipment
A pressure washer is one of the most valuable tools for any exterior cleaning business or homeowner looking to maintain their property. But like any piece of equipment, regular maintenance is key to keeping it running efficiently and extending its lifespan. Neglecting simple upkeep can lead to costly repairs or even the need for premature replacement.
In this post, we’ll break down essential maintenance tips to keep your pressure washer in top shape, whether you’re a professional using it daily or a homeowner who pulls it out seasonally.
1. Regularly Check and Change the Oil
Just like a car engine, pressure washers with gas engines require regular oil changes to keep them running smoothly.
How to Do It:
Check the oil level before each use. Look for signs of contamination, such as a milky appearance, which indicates water is mixing with the oil.
Change the oil after the first 5 hours of use (for new equipment) and then every 50 hours of operation or at least once per season.
Use SAE 10W-30 for most gas-powered pressure washers, but always check your user manual for specific recommendations.
Pro Tip: Always change the oil after the engine has cooled down to prevent burns and ensure proper drainage.
3. Flush the Detergent System After Every Use
If you use your pressure washer with detergents or soft washing solutions, it’s important to flush the system with clean water after each use to prevent buildup.
How to Do It:
• Run clean water through the detergent tank and hose for a few minutes after using soap.
• This prevents clogs and corrosion in the detergent injection system, keeping your pressure washer running smoothly.
4. Protect the Pump with Proper Care
The pump is the heart of your pressure washer. Without proper maintenance, it can overheat or suffer from cavitation (air bubbles forming inside), leading to expensive repairs.
How to Do It:
Always make sure water is flowing before starting the pressure washer to avoid running the pump dry.
Use pump protector or antifreeze when storing the pressure washer for extended periods, especially during the off-season.
Never leave the washer running for more than 2 minutes without pulling the trigger -this can cause the pump to overheat.
5. Inspect and Replace Hoses and Nozzles
Pressure Washer Maintenance Tips
.
Damaged hoses and nozzles not only reduce performance but can also be dangerous. A cracked hose can burst under pressure, and worn-out nozzles can cause uneven spray patterns or reduce cleaning power.
How to Do It:
Inspect hoses for cracks, leaks, or bulges before every use. Replace damaged hoses immediately.
Check nozzles for clogs or wear. If the spray pattern is uneven, it’s time to clean or replace the nozzle.
Use a nozzle cleaning tool to remove debris and mineral deposits from the nozzle tips.
6. Use the Right Nozzles and Settings
Using the wrong nozzle can damage both your equipment and the surfaces you’re cleaning.
Color-Coded Nozzle Guide:
Red - (0*), Most powerful, direct spray. Best for tough stains on concrete but can damage softer surfaces.
Yellow (15*), Good for heavy-duty cleaning like paint stripping or mildew removal.
Green (25*), Ideal for general-purpose cleaning- siding, driveways, decks.
White (40*). Best for delicate surfaces like windows or cars.
Black (65*): Low-pressure nozzle for applying detergents and soft washing solutions.
7. Store Your Pressure Washer Properly
When the cleaning season is over, proper storage ensures your pressure washer is ready to go when you need it.
How to Do It:
Drain the fuel or add a fuel stabilizer to prevent the gas from going bad.
Disconnect and drain all hoses and accessories to prevent freezing and cracking.
Store the pressure washer in a cool, dry place away from direct sunlight and moisture.

4. Test the spray pattern of nozzles for consistency.

6. Store equipment properly to prevent corrosion and freezing.
