To avoid this mistake, always consult your pressure washer’s manual to select the correct nozzle for each cleaning task.

What Is the Most Common Cause of a Pressure Washer Going Faulty?

Understanding the leading cause of pressure washer malfunctions is pivotal for the maintenance and optimal performance of your equipment during the cleaning process. The primary reason pressure washers may develop faults is typically rooted in improper maintenance practices and neglect.

Here are some common maintenance mistakes to avoid:

• Skipping regular maintenance.
  Pressure washers are not a set-and-forget tool; they require diligent and routine maintenance to remain in good working condition. Neglecting essential tasks such as changing the oil, cleaning or replacing filters, and inspecting hoses and nozzles can lead to eventual breakdowns and costly repairs.
• Allowing water to freeze inside the system.
  If you reside in an area with harsh, cold winters, it becomes imperative to winterize your pressure washer. Failing to do so can have dire consequences. Water left inside the system during freezing temperatures can transform into ice, causing it to expand and potentially inflict severe damage to internal components. This can result in costly repairs and downtime when you need the pressure washer the most.
• Overlooking fuel-related issues.
  For gas-powered pressure washers, issues related to fuel can frequently be a common source of problems. Whether it’s using stale or contaminated fuel, encountering clogged fuel filters, or grappling with carburetor issues, these fuel-related problems can lead to significant engine troubles. Neglecting fuel-related maintenance can leave you with a non-functional pressure washer when you need it most.
• Not addressing leaks promptly.
  Leaks in the pressure washer’s hoses, connections, or pump should never be ignored or underestimated. When you observe any leaks, it is absolutely crucial to address them promptly. Failing to do so can result in further damage to the equipment and a reduction in its overall performance. Leaks not only waste water but can also compromise the effectiveness of the pressure washer, leading to subpar cleaning results.
  

By avoiding these common maintenance pitfalls and proactively addressing issues as they arise, you can ensure that your pressure washer remains reliable, efficient, and ready for use whenever you need to tackle the cleaning tasks of your commercial building. Proper maintenance is the key to a long-lasting and effective pressure washer.

What Cannot Be Power Washed?

While power washing is undoubtedly a versatile and effective method for cleaning a wide range of surfaces, it’s important to recognize that not all materials and surfaces can withstand the force of high-pressure water. Here are some specific materials and surfaces that should never be subjected to power washing:

Electrical Fixtures And Outlets

Electrical fixtures, outlets, and components should never be directly exposed to a power washer’s spray. The combination of water and electricity is a hazardous one, and attempting to power wash near electrical sources can lead to electrical shocks, short circuits, and other dangerous situations. Always exercise extreme caution and avoid spraying water on or near any electrical components.

Delicate or Damaged Surfaces

Power washing can be overly aggressive for surfaces that are delicate or already in a state of disrepair. Delicate materials such as old wood, aging stucco, or surfaces with damaged paint are susceptible to further deterioration or peeling when subjected to high-pressure water. In such cases, it’s advisable to explore alternative cleaning methods that are gentler and less likely to cause additional damage.

Windows and Glass

High-pressure water can pose a significant risk to windows and glass surfaces. The force of the water can cause windows to crack or shatter, leading to costly replacements. When working near windows and glass, it’s crucial to exercise extreme caution. Consider using lower pressure settings or opting for handwashing methods to clean these delicate surfaces safely.

Loose or Damaged Siding

If your building’s siding is already loose or in a state of disrepair, power washing can exacerbate the situation. The force of the water can push its way behind loose siding, potentially leading to moisture issues and the development of mold or mildew. In such cases, it’s advisable to address the siding’s structural issues before considering power washing as a cleaning method.

What Should I Spray Before Pressure Washing?

To maximize the effectiveness of your pressure washing efforts and prevent further damage to surfaces, it’s essential to pre-treat certain areas before using the pressure washer. Here are some common pre-treatment steps:

1. Apply a cleaning solution: Use a commercial cleaning solution or a mixture of water and detergent to pretreat heavily soiled or stained areas. Allow the solution to sit for a few minutes before starting the pressure washer.
2. Remove loose debris: Before pressure washing, remove any loose debris, such as leaves, dirt, or cobwebs, from the building’s surfaces. This step prevents the pressure washer from pushing debris further into crevices.
3. Wet the surface: It’s a good practice to wet the surface you intend to clean before using the pressure washer. This helps loosen dirt and makes the cleaning process more efficient.

Streaks on the surfaces of commercial buildings can detract from their overall appearance and are often the result of improper pressure washing techniques. To achieve a streak-free clean and ensure that your commercial building looks its best, follow these essential tips:

Maintain a Consistent Distance

One of the fundamental aspects of avoiding streaks while pressure washing is to keep the pressure washer nozzle at a consistent distance from the surface being cleaned. Varying the nozzle’s distance can result in uneven streaks, as the force of the water will be inconsistent. Typically, maintaining a distance of 6 to 12 inches between the nozzle and the surface is recommended. This consistent distance ensures that the cleaning effect is uniform across the entire area.

Use a Detergent or Cleaning Solution

To enhance the effectiveness of your pressure washing and prevent streaking, consider applying a suitable cleaning solution or detergent before using the pressure washer. A cleaning solution can help break down and dissolve stubborn grime, making it easier to remove. It also aids in preventing streaks by promoting an even distribution of cleaning agents. However, remember to thoroughly rinse the surface after applying the solution to remove any residues.

Work in Small Sections

Dividing the exterior of the commercial building into manageable sections is a prudent strategy for preventing streaks. By cleaning one section at a time, you can ensure a thorough and methodical approach to the cleaning process. This not only prevents streaks from forming but also allows you to focus on specific areas that may require more attention. Additionally, cleaning in smaller sections prevents streaks from drying on the surface before you have a chance to rinse them away.

Rinse Thoroughly

After completing the pressure washing process, it’s crucial to rinse the surface thoroughly with clean water. Inadequate rinsing can leave behind detergent residues or debris, which can result in streaks as the surface dries. Be meticulous in your rinsing efforts, ensuring that all cleaning agents and contaminants are fully removed. A thorough rinse will leave the surface looking clean and streak-free.

Pressure washing is a valuable tool for maintaining the cleanliness and appearance of commercial buildings. However, it’s essential to use this powerful tool correctly to avoid common mistakes that can lead to damage or inefficiency. By understanding what not to do when pressure washing, addressing common maintenance issues, and following proper pre-treatment and cleaning techniques, you can achieve a clean and streak-free result while preserving the integrity of the building’s surfaces. Remember that safety should always be a priority when operating pressure washing equipment, and when in doubt, consult the manufacturer’s guidelines or seek professional assistance at First State Services to ensure a successful cleaning process.
