– **Stiff-bristle brush**
– **Squeegee**
– **Safety goggles and gloves**
Remove all items from the garage. Sweep away loose debris. Cover nearby electrical outlets. Pre-treat oil stains with degreaser and let sit for 10 minutes.
### **Step 1: Set the Right Pressure and Nozzle**
Use a **25-degree nozzle** for concrete. Keep PSI between 1,500 and 3,000—too much pressure etches concrete. Test on a small hidden area first.
### **Step 2: Apply Cleaner and Scrub**
Spray degreaser evenly. Scrub stubborn spots with a stiff brush. Let the solution dwell for 5–10 minutes but don’t let it dry.
### **Step 3: Pressure Wash in Sections**
Work in 4×4 foot sections. Hold the wand 12–18 inches from the surface at a 45-degree angle. Use overlapping strokes. Start from the farthest corner and push water toward the garage door.
### **Step 4: Rinse and Squeegee**
Rinse the entire floor with clean water. Use a squeegee to remove standing water. Repeat for heavily soiled areas.
### **Step 5: Allow to Dry and Inspect**
Let the floor dry completely (4–6 hours). Check for missed spots. Apply a concrete sealer for long-lasting protection.
### **Common Mistakes to Avoid**
– Using a 0-degree nozzle (causes etching)
– Getting too close to the surface
– Skipping degreaser on oil stains
– Washing on a windy day (spreads mess)
### **Frequently Asked Questions**
