Expert Oil Stain Removal & Degreasing
Across Southampton & Hampshire
Advanced hot water pressure washing and eco-friendly treatments for driveways, patios, and commercial car parks.

We follow a meticulous multi-stage process to ensure the best possible results. First, our technicians apply specialist, eco-friendly degreasers that are formulated to break down stubborn oil bonds deep within porous substrates like block paving, concrete, and tarmac. Once the chemical has had time to dwell, we deploy high-temperature hot water pressure washing equipment. This thermal action is essential for liquefying hardened grease, allowing us to rinse away the residue without causing structural damage to the surface. We conclude by ensuring the surrounding area is left tidy and, where applicable, re-sanding block paving to restore its structural integrity.

Many DIY methods or standard cold-water jet washing fail to lift deep-set oil stains because they cannot emulsify the grease. Professional hot water jet washing is the gold standard for surface restoration as it rapidly breaks down the molecular structure of hydrocarbons. By using professional-grade heating technology, we can achieve a cleaner finish while using lower pressures, which protects the long-term longevity of your driveway or car park. This approach is significantly more effective than manual scrubbing or using household cleaning agents which are often ineffective on heavy-duty spills.

We take our responsibility towards the environment seriously. As a professional exterior cleaning company, we are fully aware of strict drainage regulations and the potential impact of oil run-off. Under Pressure Southern adheres to local and national guidelines regarding trade effluent and spill management. We use biodegradable degreasers that are tough on oil but gentle on the surrounding environment and garden life. When cleaning commercial car parks or industrial sites, we implement containment measures to prevent contaminated water from entering local drainage systems, ensuring full regulatory compliance at every stage of the project.
