Pro Tip: Make sure to pre-wet the surfaces you will be pressure washing before applying any cleaning solution. This will help the detergent penetrate the dirt and grime more efficiently.

Preparing the Exterior Surfaces

Before starting the pressure washing process, you must properly prepare the exterior surfaces of your house. Follow this pre-pressure wash checklist to ensure a successful cleaning:

  1. Remove any outdoor furniture, decorations, or items that may obstruct the cleaning process.

  2. Cover delicate areas such as plants, outdoor lights, and electrical outlets with plastic or tarp to protect them from damage.

  3. Close all doors, windows and vents to prevent water from entering the house or causing damage to the interior.

  4. Check for any damages or loose materials such as cracks, chips, or damaged paint. Repair or replace them before starting the pressure washing process.

  5. Sweep and remove any debris or loose dirt from the surfaces to prevent clogging the pressure washer or causing damages.

Now that you have completed the prepping stage, let's move on to the different surfaces you may encounter and how to properly prepare them for pressure washing.

Safety Precautions and Best Practices

Pressure washing is a fantastic way to clean and beautify your home's exterior, but it's essential to take the necessary safety precautions to prevent injuries and damages to your property. Here are some of the best practices for pressure washing:

Wear Protective Clothing

Before you start pressure washing, make sure you are wearing proper protective clothing, including goggles, gloves, and closed-toe shoes. These will protect you from debris, chemicals, and other hazards.

Avoid Electrical Hazards

When using an electric pressure washer, make sure it's plugged into a grounded outlet with a Ground Fault Circuit Interrupter (GFCI) to prevent electrical hazards. Do not use an extension cord, and keep the power cord away from water and other liquids.

Use Proper Techniques

Be sure to use proper techniques when pressure washing to prevent injuries and damages. Always point the spray gun away from yourself and others, and never spray water at an angle that could damage windows or other delicate surfaces.

Follow Manufacturer's Instructions

Read and follow the manufacturer's instructions for your pressure washer before use. This will ensure that you are using it correctly and safely.

Test Surface Before Pressure Washing

Before pressure washing, test a small area of the surface to make sure the pressure and spray pattern are appropriate. This will prevent damage to the surface being cleaned.

Don't Pressure Wash Hazardous Materials

Never pressure wash hazardous materials such as asbestos, lead paint, or mold. These require special handling and disposal.

Be Mindful of Surrounding Areas

When pressure washing, be mindful of surrounding areas, such as plants, cars, and outdoor furniture. Cover or move these items to prevent damage.

By following these pressure washing safety precautions and best practices, you can ensure a safe and efficient cleaning process for your home's exterior.
