## How to Power Wash Your Garage Floor: A Step-by-Step Guide for a Spotless Concrete Surface
Your garage floor endures oil stains, dirt, and grime that a broom can’t fix. Learning to **power wash a garage floor** transforms that dull slab into a clean, safe surface. This guide walks you through every step.
### Why **Clean Concrete Floors** Matter
A dirty floor isn’t just ugly. **Mold and mildew** thrive in damp garages, and **oil stains** create slippery hazards. Regular **pressure washing** removes deep-set grime, extends concrete life, and improves curb appeal.
### **Essential Tools and Materials**
Before you start, gather these items:
– **Pressure washer** (2,500–3,000 PSI)
– **Degreaser** or concrete cleaner
– **Stiff-bristle brush**
– **Safety goggles and gloves**
– **Wet/dry shop vac** or squeegee
A **gas or electric pressure washer** with a **25-degree nozzle** works best for concrete.
### **Preparing the Garage Area**
Clear everything out. Sweep loose debris first—**pressure washing** over leaves just makes a mess. Cover nearby outlets with plastic, and check for cracks you may need to patch afterward.
### **Applying Degreaser for Stubborn Stains**
**Oil stains** need pretreatment. Apply a **concrete degreaser**, let it sit 10–15 minutes, then scrub with a stiff brush. This loosens grime so your **power washer** rinses it away easily. For heavy stains, repeat the process.
### Step-by-Step **Pressure Washing Technique**
1. **Work in sections.** Divide the floor into 4×4-foot squares.
2. **Keep the nozzle moving.** Hold it 8–12 inches away at a consistent angle.
3. **Overlap your strokes.** This prevents zebra striping.
4. **Rinse thoroughly.** Push dirty water toward the garage door.

### **Drying and Post-Cleaning Care**
Use a **squeegee** or **shop vac** to remove standing water. Let the floor air-dry for 24 hours. Once dry, consider applying a **concrete sealer** to repel future stains and simplify cleaning.
### **Common Mistakes to Avoid**
– **Too much pressure.** High PSI can etch concrete.
– **Skipping pretreatment.** Cold water alone won’t cut grease.
– **Ignoring drainage.** Standing water can seep into walls.
