How to Pressure Wash a Driveway: A Step-by-Step Guide

Your driveway can be way more than just a place to park your car - it can actually increase your curb appeal! That is, unless the driveway in question has accumulated dirt, grime, oil stains, and organic growth like mildew. This not only diminishes your driveway’s appearance, it can also potentially cause damage.

This is where the power of pressure washing or power washing comes in. Regularly pressure washing your concrete driveway, brick driveway, or even pavers not only restores it to cleanliness but also prolongs its lifespan. It might not be the first thing you think of when trying to make your property look great, but driveway cleaning is an essential part of home maintenance for all homeowners!

Why You Should Pressure Wash Your Driveway

When you fail to clean your driveway’s surface, it can lead to a buildup of substances that are not attractive, but also potentially damaging. Moss, algae, and mildew can grow in damp, shaded areas, leading to slippery surfaces and potential cracks. Oil and grease stains from vehicles can actually penetrate the surface - causing stubborn stains and weakening the material.

All you have to do to prevent those scenarios is remember to regularly pressure wash your driveway! High-pressure water from a pressure washer effectively removes these stains and other grime, preventing long-term damage and maintaining the structural integrity of your driveway.

What You Need to Pressure Wash Your Driveway

To achieve a spotless driveway, you'll need the right tools, cleaning solution, and a systematic approach. Let’s go over the tools and equipment needed to do this job correctly.

Essential Tools and Equipment

• Pressure Washer: There are two choices as far as types of pressure washers - gas pressure washers and electric pressure washers. Each has their own pros and cons that we will explain here:
  
  • Gas pressure washers offer higher pressure (PSI) and flow rates (GPM), making them ideal for large driveways and stubborn stains.
  • Electric pressure washers are quieter, more environmentally friendly, and suitable for smaller driveways and lighter cleaning tasks.
• Surface Cleaner Attachment: By attaching this to your pressure washer, it will provide a wide, even spray pattern. This will significantly reduce the length of the cleaning process and will also prevent streaking.
• Extension Wand/Spray Wand: An extension wand is crucial for reaching hard-to-access areas and keeps you from having to assume awkward positions and straining your back!
• Safety Gear: As always, safety first! Always wear safety gear, including safety goggles and closed-toe shoes, to protect yourself from any debris flying around as well as potential slips.
• Garden Hose: In order to make all of this work, you will need a functioning garden hose! That is what you will connect to your pressure washer for water supply.

Cleaning Solutions and Detergents

For concrete surface, use a heavy-duty alkaline degreaser designed to remove oil, grease stains, and grime. For asphalt, opt for a milder detergent to avoid damaging the surface. Always check the manufacturer's recommendations for specific surface types.

There are also some environmentally friendly options! Look for biodegradable and phosphate-free detergents to minimize environmental impact. Some people also use diluted bleach solutions, but this must be done with extreme care. Using these cleaning solutions and detergents may require a separate sprayer for pre-treating hard to remove stains.

Step-by-Step Guide to Pressure Washing Your Driveway

Pressure washing your driveway can be a straightforward DIY project for homeowners with the time and equipment. Let’s go over the process step by step!

Step 1: Prepare the Driveway

• Clear any and all debris, including rocks, leaves, and trash, from the entire driveway.
• Cover surrounding plants and fixtures with plastic sheeting to protect them from overspray - especially if it has detergent or cleaning solution added to it. This is also important for your nearby landscaping.

Step 2: Set Up Your Pressure Washer

• Connect the water hose to the pressure washer and the water source.
• If using detergent, fill the detergent tank or connect the siphon hose.
• Adjust the amount of pressure by choosing a setting according to the surface type and the level of dirt and grime.

Step 3: Test the Pressure on a Small Area

• Before starting, it is always a good idea to test the pressure on a small, inconspicuous area of the driveway. This step is crucial to prevent damage from too much pressure.
• Adjust the nozzle and pressure settings as needed.

Step 4: Start Washing Your Driveway

• Use even, overlapping sweeps to ensure consistent cleaning.
• Maintain a safe distance between the nozzle and the driveway surface to avoid damaging the driveway surface.
• Do not forget the corners! Clean corners and edges thoroughly using a narrower spray pattern or by using an extension wand.

Step 5: Rinse and Dry the Driveway

• Rinse the driveway thoroughly after you have finished using clean water to remove all detergent residue.
• Allow the driveway to air dry completely. For faster drying, you can always use a squeegee to remove excess water. If you plan to apply a sealer, the driveway must be completely dry.

Tips for the Best Results When Pressure Washing a Driveway

There is a method for cleaning just about any stubborn stain you can find on a driveway surface! If it is an oil stain, simply apply a degreaser or a specialized oil stain remover before pressure washing. For very old stains, you may need to repeat the process more than once.

For rust, use a rust remover or a solution of oxalic acid to loosen rust stains before pressure washing. Got tire marks? A strong alkaline detergent or a tire mark remover can help break down these stubborn stains. A pressure washer surface cleaner is very helpful for this as well!

If the stain is still refusing to go, try using a higher pressure setting. In extreme cases, a rotary nozzle could be used, but make sure to be very careful or you could damage the surface.

How to Avoid Common Mistakes

Here are some of the common pitfalls regarding pressure washing your driveway surface. Each one is avoidable if you follow this advice.

• Not damaging the driveway surface: Always test the pressure on a small area first and avoid using more pressure than is needed.
• Over-wetting the area: Do not spray for too long in one spot, as this can lead to water damage.
• Incorrect Sealer Application: If you plan to add a sealant or sealer, make sure that you use the correct product for your driveway surface material. Also, be very sure that the driveway is completely dry.

When to Hire a Professional Pressure Washer

For large driveways or difficult stains, you may want to consider hiring professional pressure washing or pressure washing services. Professionals have the experience, equipment, and expertise to handle the more difficult pressure washing job tasks with ease.

How Often Should You Pressure Wash Your Driveway?

Some factors that can affect how often you should pressure wash your driveway include weather, traffic, and location. Weather conditions, such as excessive rain or snow, can mean more dirt and grime on your driveway surface. As you might expect, driveways that see a lot of traffic need more frequent cleaning. Location is also a factor. For example, driveways under trees with falling leaves and other debris will need more regular cleaning. Usually, once or twice a year is enough to maintain your driveway.

Benefits of pressure washing your driveway surface

Pressure washing comes with a lot of benefits, including saving you money. Regular pressure cleaning prevents the buildup of damaging substances, extending the lifespan of your driveway and avoiding costly repairs or replacements. Other benefits include:

• Removes stubborn stains, dirt, and grime, making your driveway look like new again!
• Prevents damage like cracks and deterioration of the driveway surface.
• Improves the curb appeal of your home, enhancing its property value.
