Common Driveway Cleaning Questions to Help Our Customers Who Pressure Wash
If you provide driveway cleaning services or use a pressure washer to clean driveways, you may encounter various challenges. Here are some frequently asked questions to help you achieve the best results and avoid common mistakes.
What PSI and Nozzle Should I Use for Driveway Cleaning?
- PSI: 2500-4000 PSI is ideal for concrete and block paving.
- Nozzle: A 15° (yellow) or 25° (green) nozzle is best for deep cleaning without causing damage.
- Surface Cleaner: Using a surface cleaner attachment ensures an even clean without streaks.
How Do I Remove Oil Stains from a Driveway?
- Apply a degreaser or detergent and let it soak for 10-15 minutes.
- Scrub with a stiff brush if needed.
- Pressure wash with hot water if available.
- Repeat if necessary for deep stains.
For stubborn stains, use a
commercial-grade degreaser or a baking soda paste for eco-friendly cleaning.
How Do I Prevent Streaks When Cleaning a Driveway?
- Use a surface cleaner instead of a spray wand for even cleaning.
- Keep the nozzle moving and maintain a consistent distance.
- Overlap each pass to prevent missed spots.
- Rinse thoroughly to remove detergent residue.
Should I Use Hot or Cold Water for Driveway Cleaning?
- Cold water works for general dirt, mud, and algae.
- Hot water (or a steam cleaner) is better for oil, grease, and stubborn stains.
If you don’t have a hot water system, using a degreaser before pressure washing helps break down stains.
How Often Should a Driveway Be Pressure Washed?
This depends on weather conditions and traffic, but general recommendations are:
Every 6-12 months for routine cleaning.
Every 3-6 months if exposed to heavy dirt, moss, or oil spills.
Regular cleaning prevents stains from setting and extends the life of the driveway.
Can I Pressure Wash a Driveway in Winter?
Yes, but be cautious:
- Avoid washing in freezing temperatures (water can refreeze and cause hazards).
- Use hot water to speed up drying.
- Apply a sealant after washing to protect against frost damage.
How Do I Remove Moss and Weeds from Block Paving?
- Apply a biodegradable moss and algae treatment before washing.
- Use a turbo nozzle or surface cleaner to lift stubborn growth.
- Re-sand the joints with kiln-dried sand after cleaning to prevent weed regrowth.
Do I Need to Seal a Driveway After Pressure Washing?
Sealing is recommended for:
Block paving – Prevents weed growth and enhances colour.
Concrete driveways – Protects against stains and cracks.
Tarmac driveways – Helps restore and protect the surface.
A quality sealant can extend the cleanliness and longevity of the driveway.
Can I Use Bleach to Clean a Driveway?
Bleach can be used for algae and mould removal but:
Dilute it properly (1 part bleach to 10 parts water).
Avoid runoff into plants and grass.
Rinse thoroughly to prevent residue damage.
For eco-friendly alternatives, use a
biodegradable detergent or a vinegar-based solution.
How Can I Make My Driveway Cleaning Service Stand Out?
If you offer driveway cleaning as a business, here are some ways to attract more customers:
- Use before-and-after photos in your marketing.
- Offer additional services like sealing or soft washing.
- Provide eco-friendly cleaning options.
- Educate customers on maintenance to keep their driveways cleaner for longer.
