Frequently Asked Questions About Pressure Washing

What are the different types of pressure washer nozzles?

Pressure washer nozzles come in various spray patterns and angles, each designed for specific cleaning tasks:

• 0-degree Nozzle: Produces a highly concentrated, powerful jet of water for removing stubborn stains or stripping paint. Use with caution as it can damage surfaces easily.
• 15-degree Nozzle: A versatile nozzle for cleaning concrete, brick, and other hard surfaces. Provides a good balance of pressure and coverage.
• 25-degree Nozzle: A wider spray pattern for cleaning delicate surfaces like siding or fences.
• 40-degree Nozzle: A very wide spray pattern, ideal for rinsing or applying cleaning solutions.
• Soap Nozzle: A low-pressure nozzle designed specifically for applying cleaning solutions.
• Rotary Nozzle: Also known as a turbo nozzle, it produces a rotating, high-impact spray for tackling tough stains and grime.

Choose the appropriate nozzle based on the cleaning task and the type of surface being cleaned. Consult the pressure washer manual or a professional pressure washer for guidance.

What is the best time of year for pressure washing?

The best time of year for pressure washing depends on the weather conditions in your area:

• Spring and Fall: Spring and fall are often ideal for pressure washing as the temperatures are moderate and the weather is typically dry.
• Summer: Pressure washing can be done in the summer, but avoid doing so during the hottest part of the day to prevent the cleaning solutions from drying too quickly and leaving streaks.
• Winter: Pressure washing is possible in the winter, but be mindful of freezing temperatures that can affect cleaning solutions and cause slippery surfaces.

Choose a day with mild temperatures and dry weather for optimal pressure washing results. Avoid pressure washing in extreme heat, freezing temperatures, or rainy conditions.

Can pressure washing damage my deck?

Pressure washing can damage wood decks if done improperly. High pressure can etch or splinter the wood, leading to a rough and uneven surface.

• Soft Washing: Soft washing is generally recommended for wood decks as it uses lower pressure and specialized cleaning solutions to safely remove dirt, mildew, and algae without causing damage.
• Lower Pressure Setting: If using a pressure washer on a wood deck, use a lower pressure setting (around 1500 PSI) and a wide-angle nozzle (25-40 degrees).
• Maintain Distance: Hold the nozzle at least 12 inches away from the deck surface to prevent etching or splintering.
• Professional Pressure Washing: If you're unsure about pressure washing your deck safely, hire a professional pressure washing company with experience in cleaning wood surfaces.

By using the right cleaning method and precautions, you can effectively clean your wood deck without causing damage and prolong its lifespan.

How often should I pressure wash my house?

The recommended frequency for pressure washing your house depends on factors like your location, surrounding environment, and the type of siding. As a general guideline:

• Annually: Pressure washing your house at least once a year helps remove accumulated dirt, grime, and other contaminants, keeping it looking its best.
• Every 2-3 Years: If you live in an area with high humidity, heavy tree cover, or frequent exposure to pollutants, more frequent pressure washing may be necessary.
• When Visible Dirt and Grime Appear: Address visible dirt, stains, or mold growth promptly to prevent them from becoming more challenging to remove.

Regular pressure washing can maintain your home's exterior, extend the lifespan of your siding, and enhance its curb appeal.
