### **Step 1: Clear and Prep the Area**
Remove cars, tools, and storage. Sweep away loose debris. **Pre-treat oil stains** with a degreaser and let it sit 10–15 minutes. This step prevents spreading grime.
### **Step 2: Choose the Right Nozzle and Pressure**
Use a **25-degree nozzle** for concrete. Keep pressure between **1500–3000 PSI**. Too much pressure etches the surface; too little won’t clean. A **surface cleaner attachment** ensures even results.
### **Step 3: Apply Detergent**
Use a **concrete-safe cleaner**. Apply from bottom to top to avoid streaking. Let it dwell, then scrub stubborn spots with a stiff brush.
### **Step 4: Rinse in Sections**
Work in **4×4-foot sections**. Rinse top to bottom with smooth, overlapping passes. This prevents dirty water from drying on clean areas.
### **Step 5: Squeegee and Dry**
Push water out the garage door. Use a squeegee for even drying. Let the floor air-dry completely before parking.
### **Common Mistakes to Avoid**
– Using a **0-degree nozzle** (causes etching)
– Skipping degreaser on oil spots
– Washing on a windy day (spreads mist)
