### Step 1: Prep the Area
Remove vehicles, tools, and debris. **Sweep the entire slab** to prevent grit from scratching the surface. Cover nearby electrical outlets and check for cracks that water could worsen.

Oil stains need pre-treatment. Apply a **concrete-safe degreaser** and let it dwell 5–10 minutes. This breaks down stubborn grease so your washer rinses it cleanly.

Work in 4×4-foot sections with overlapping passes. Hold the wand 6–12 inches away at a 45-degree angle. This **prevents water pooling** and ensures uniform coverage.
### Step 5: Rinse and Repeat
Rinse the entire floor with clean water. For heavy stains, repeat degreaser and washing. Let the slab air-dry completely before parking.
