In Pressure Cleaning

This guide is designed to help you learn about 20 pressure-washing mistakes that homeowners should steer clear of, ensuring that your house stays in pristine condition for years to come.

20 High-Pressure Cleaning Mistakes to Avoid for Your Home

1. Washing in the Wrong Sequence

Pressure washing is a systematic process that requires a well-thought-out plan. Commencing the cleaning process without considering the sequence of tasks can lead to water and grime trickling onto surfaces that have already been cleaned. This can render your efforts futile and necessitate redoing certain areas. To circumvent this, begin by tackling the highest surfaces first, such as the roof, and work your way downwards. This ensures that dirt and water flow naturally away from surfaces that have already been cleaned.

2. Lack of Knowledge

While high-pressure cleaning might appear straightforward, it’s more nuanced than it seems. Insufficient knowledge about the appropriate pressure settings, nozzle types, and cleaning agents can have unintended consequences. This includes surface damage, poor cleaning results, or even personal injury. Before embarking on a pressure washing project, take the time to educate yourself about the specific requirements for different surfaces and stains. This knowledge will empower you to use your pressure washer effectively and safely.

3. Excessive Pressure

The allure of a quick and forceful cleaning might prompt you to crank up the pressure, but this can prove detrimental to your home’s surfaces. Excessive pressure can strip away paint, gouge wood, and even force water underneath siding or shingles. Always begin with the lowest pressure setting and gradually increase it as needed. This cautious approach guarantees that you achieve effective cleaning without causing damage.

4. Breaking Windows

One of the most common and potentially costly mistakes in high-pressure cleaning is directing pressure water towards windows. The intense force can lead to shattered glass and result in additional expenses for window replacements. When cleaning window glasses, opt for lower pressure settings and wider fan nozzles. Alternatively, consider using a squeegee or a specialised window cleaning tool to avoid the risk altogether.

5. Hiring the Wrong Company

For those who are unsure about handling a pressure washer themselves, hiring a professional high-pressure cleaning service in Hobart is a prudent choice. However, the quality of workmanship varies among service providers. Entrusting your home to an inexperienced or unreliable company can lead to subpar results, potential damage, and unwarranted expenses. Research and select a reputable company with a track record of delivering exceptional pressure washing services.

6. Using Only Water

While water is the fundamental component of pressure washing, it might not suffice to tackle all types of stains. Grease, oil, mould, and mildew often require specialised cleaning solutions to achieve optimal results. Utilise appropriate cleaning agents for various surfaces and stains, enhancing the efficiency of the washing efforts and preventing future growth.

7. Not Protecting Landscaping

The potent force of a pressure washer can unintentionally dislodge mulch, damage plants, and erode soil. It’s imperative to safeguard your landscape by covering delicate plants and shrubs with plastic sheeting before initiating the cleaning process. This simple precautionary step prevents inadvertent harm to your outdoor greenery.

8. Power-Washing Painted Surfaces

Using excessive pressure on painted surfaces is a recipe for disaster. The force can strip away the paint, leaving your surfaces vulnerable to the elements. To safeguard painted areas while effectively removing dirt, adjust the pressure settings and employ wider fan nozzles. This approach ensures that you clean painted surfaces without compromising their integrity.

9. Power-Washing Mould-Prone Surfaces

While high-pressure cleaning is effective at removing mould, directly blasting mould-prone surfaces can scatter the spores into the air, potentially exacerbating the problem. To mitigate this, use specialised mould cleaners in conjunction with a gentler pressure wash. This combination not only eliminates existing mould but also reduces the likelihood of spore dispersion.

10. Using Hot Water

Hot water can be an asset when tackling greasy or oily surfaces. However, exercise caution when applying it. Delicate materials like vinyl siding can warp under high temperatures, leading to unsightly deformations. Consider the material and type of surface you’re cleaning before deciding to use hot water.

11. Not Being Familiar with Your Equipment

Before embarking on any pressure washing endeavour, familiarise yourself with the equipment. Read the user manual thoroughly, acquaint yourself with the different nozzle options, and practice in an inconspicuous area to understand the power of the machine. This knowledge empowers you to utilise your pressure washer effectively and confidently.

12. Storing a Pressure Washer with Water in It

Leaving water in your high-pressure cleaning machine between uses can lead to internal corrosion or even freezing during cold weather. To prolong the life of your machine, always empty the water and store it properly in a dry and cool location.

13. Forgetting to Angle the Spray

A common oversight is holding the washer wand perpendicular to the surface being cleaned. This can force water into cracks, seams, or beneath surfaces. To prevent this, angle the spray slightly downward, allowing water to run off harmlessly without infiltrating vulnerable areas.

14. Not Using Safety Equipment

Pressure washing involves high-pressure water that can cause injuries if it comes into contact with your skin or eyes. Prioritise safety by wearing protective goggles, suitable footwear, and gloves. These precautions shield you from potential harm and enhance your overall safety while working with the equipment.

15. Using the Wrong Nozzle

High-pressure cleaning equipment comes with various nozzle options, each producing distinct spray patterns and pressures. Choosing the wrong nozzle for a specific task can result in damage to surfaces or inefficient cleaning. Thus, it is wise to hire professionals to achieve a smooth and flawless job.

16. Spraying Upward Against Siding

Directing the pressure washer spray upward against the siding, shingles, or other surfaces can force water behind them, leading to moisture-related problems and mould growth. To avoid such complications, always direct the spray downward, following the natural flow of water.

17. Using a Gas-Powered Pressure Washer Indoors

Gas-powered pressure washers emit harmful fumes, rendering them unsuitable for indoor use. Opt for electric pressure washers when cleaning indoor spaces to ensure air quality and personal safety.

18. Not Protecting the Surrounding Area

High-pressure cleaning can generate a considerable mess. Before you commence cleaning, take measures to safeguard your outdoor furniture, cover electrical outlets, and shield items that may be vulnerable to water or cleaning agents.

19. Not Allowing Surfaces to Dry Completely

After pressure washing, it’s crucial to allow surfaces to dry thoroughly before applying any coatings like paint, stain, or sealant. Painting over damp surfaces can lead to poor adhesion and premature peeling, undermining the durability of your efforts.

20. Not Having a Plan

Randomly attacking your cleaning tasks without a clear strategy can result in an incomplete job and missed spots. To ensure thorough and consistent results, divide your cleaning projects into manageable sections and follow a systematic approach.

FAQs About High-Pressure Cleaning Your Home
