The best pressure washer nozzle to clean a driveway is a surface cleaner with three wheels to ensure you get smooth, even coverage. The attachment allows you to deep clean a driveway’s large surface without much strain on your body, especially if you add two extender wands. Choose a pressure washer that offers 2500 to 3000 PSI and about 3 gallons of water per minute.

You should never use bleach in a pressure washer. While bleach is effective at killing mold and mildew, it is a potent chemical that can corrode the machine's seals and nozzles, destroying it from the inside out. Additionally, pressure washing with bleach sprays the chemical into the air, which is dangerous if inhaled and can kill nearby plants, flowers, or harm animals that ingest it. If you need to remove mold or mildew, it is best to hire a professional who will use a safe and effective cleaning agent.

Whether you need to winterize your pressure washer depends on where it will be stored. If it's kept in a location where temperatures could drop to freezing, any liquid left in the water pump can freeze, expand, and cause severe damage to the machine. To prevent this, you can add antifreeze to the pump. While emptying the machine with compressed air is an alternative, it can be a tedious process and may not remove all the liquid. If you can store the pressure washer in a relatively warm place with no risk of freezing, you won't need to add antifreeze. However, regardless of storage conditions, it is good practice to empty the gas chamber and refresh the oil before storing it for the winter.

Yes, you can pressure wash epoxy floors, but you must take precautions to avoid damaging the surface. While most epoxy floors can be cleaned with a mop, you might choose to pressure wash if the floor is stained, has ground-in dirt, or is covered with mold or mildew. To do so safely, first soak any stains or dirty areas with a gentle cleanser. Use a lower pressure setting with a gentle nozzle, such as a green, white, or black tip, or a 45-degree angled tip. Keep the spray nozzle at least 18 inches away from the floor to protect the surface. Using a surface cleaner attachment or a rotary scrubber can also help prevent overspray. Be cautious if using a power washer that heats the water, as the combination of heat and pressure may be too powerful and could damage the epoxy coating.
