How to Remove Oil, Mold, and Red Clay Stains from Your Driveway

If you live in Allen, TX, you've probably noticed some combination of black streaks, rusty spots, or deep red splotches on your concrete driveway. These stains are common in North Texas due to our soil composition, moisture levels, and warm climate.

Here are the biggest culprits:

• Oil and grease stains from cars and lawn equipment
• Black mold and mildew caused by shaded, damp areas
• Red clay stains — a regional issue caused by high-iron soil runoff

Why Standard Cleaning Doesn't Work

Hose water and store-bought detergents won't cut it with deeply embedded driveway stains. Concrete is porous, which means contaminants seep into the surface. Even pressure washers without the right cleaning agents won't get the job done.

At Aqua Force Pressure Wash, we use professional-grade pressure washing equipment and eco-safe detergents specifically formulated to target each stain type without damaging your driveway.

How to Remove Oil Stains from Your Driveway

Oil stains are one of the most stubborn. If untreated, they can darken and spread.

Here's our professional approach:

• Degreaser Pre-Treatment: Apply a heavy-duty degreaser and allow it to soak for 10-15 minutes.
• Hot Water Pressure Washing: Use high-temperature water to emulsify and lift the oil.
• Repeat or Spot-Treat: Stubborn stains may require a second application or brushing.

DIY tip: Kitty litter or baking soda can help absorb fresh oil spills before cleaning, but they won't remove set-in stains.

Removing Red Clay Stains

Allen's soil contains high levels of iron, which leaves behind rust-colored red clay stains after rain or landscaping work.

Standard washing can spread these stains. Our process includes:

• Specialty Clay Remover: A commercial-grade cleaner that breaks down iron-based pigments.
• Soft Brush Agitation: Gently loosens the clay from concrete pores without surface damage.
• Neutralizing Rinse: Prevents oxidation or streaking after cleaning.

Eliminating Mold and Mildew Stains

Dark, shady areas of your driveway may develop black or green mold over time. It's more than just ugly — it can be slippery and hazardous.

Our mold treatment includes:

• Algaecide/Detergent Soak: Applied to kill mold at the root level
• Low to Medium Pressure Cleaning: High pressure can damage older concrete; we adjust to the surface type
• Post-Treatment Barrier: Optional mold inhibitor helps delay regrowth
