Gas Station Cleaning — Forecourt, Canopy & Fuel Island Restoration
Gas station forecourts collect fuel stains, oil drips, tire rubber, and carbon exhaust daily. Willow Wash cleans them with hot water and full stormwater containment — compliant with California regulations.
Your Forecourt Is Your Customers' First Contact With Your Business
Gas station forecourts are subjected to fuel spills, oil drips, tire rubber deposits, and carbon exhaust buildup every single day. This contamination penetrates concrete, creates hazardous slip conditions, and violates California environmental regulations if not properly managed. A dirty forecourt signals poor maintenance to customers and invites regulatory scrutiny from environmental inspectors. Willow Wash provides specialized gas station cleaning using hot water pressure washing with appropriate petroleum-cutting degreasers and full stormwater containment protocols. Every job meets California Regional Water Quality Control Board requirements — we block drains, contain runoff, and recover all wash water. No environmental violations, no fines, no headaches.
What We Clean
Forecourt Concrete
Hot water pressure washing with petroleum degreasers removes fuel stains, oil drips, tire rubber, and ground-in grime from the full forecourt surface. Surface cleaner attachments for streak-free, consistent results.
Fuel Island Surfaces
Targeted cleaning of the concrete directly beneath fuel dispensers — the highest contamination zone on the forecourt. Oil and fuel concentration here requires hot water and extended dwell time with commercial degreasers.
Canopy Structure
Soft washing for the canopy underside, supports, and fascia — removes exhaust carbon, bird droppings, grease mist, and environmental grime without damaging paint or signage.
Pump & Dispenser Area
Low-pressure cleaning around fuel dispensers, card readers, and pump housings. We protect all electrical components and clean without forcing water into equipment.
Convenience Store Exterior
Soft washing for the store facade, entry area, windows, and signage. Removes exhaust film, algae, and grime from all exterior surfaces.
Stormwater Compliance Management
Drain blocking, containment berm placement, wash water recovery, and disposal. Full environmental compliance management included on every job.
Our Process
Environmental Assessment & Drain Blocking
We identify all storm drain inlets, block them completely, and assess containment needs before any equipment starts.
Hot Water Pre-Treatment with Degreasers
Commercial petroleum degreasers applied to forecourt and fuel island surfaces with appropriate dwell time to break the bond.
Pressure Washing with Recovery Containment
Hot water pressure washing with surface cleaner. All wash water directed to recovery containment — none enters storm drains.
Wastewater Disposal & Documentation
Recovered water transported and disposed of at an approved facility. Documentation available for regulatory records.
