## How to Power Wash Your Garage: A Step-by-Step Guide for a Spotless Finish
Your garage takes a beating—oil drips, tire marks, dust, and grime build up fast. A **power wash garage** session can restore the concrete to like-new condition in just a few hours. This guide walks you through every step safely and effectively.
### Why Power Washing Your Garage Matters
Beyond curb appeal, **concrete cleaning** prevents long-term damage. Dirt traps moisture, which leads to cracks and mildew. Regular **pressure washing** also removes **oil stains** and **rust marks** before they set permanently. If you’re wondering whether your floor can handle it, learn more about whether you can power wash garage floors safely before you begin.
### Gather Your Equipment
You’ll need a **pressure washer** (2,500–3,000 PSI), a **surface cleaner attachment**, **degreaser**, a **stiff brush**, and **safety goggles**. A **garden hose** and **squeegee** help with rinsing and drying.
## Step 1: Clear and Prep the Space
Remove cars, tools, and storage. Sweep loose debris—leaves, gravel, and dust. Skipping this step clogs your **drainage system** and spreads mud.
## Step 2: Apply Degreaser to Stained Areas
Spray **concrete degreaser** on oil spots and let it sit 10–15 minutes. Agitate with a **stiff brush** for stubborn **grease stains**.
## Step 3: Power Wash the Floor
Work in sections using a **surface cleaner** for even results. Keep the nozzle 12–18 inches from the surface. Overlap strokes to avoid **striping**.
### Adjusting Pressure for Concrete
Start with a **25-degree nozzle** at moderate pressure. Too much force etches concrete; too little leaves dirt behind. Test a small corner first.
## Step 4: Clean Walls and Doors
Use a **40-degree nozzle** for **garage walls** and **siding**. Avoid spraying **electrical outlets**, **windows**, and **weather stripping**. For **garage doors**, use low pressure to protect paint.
## Step 5: Rinse and Inspect
Rinse thoroughly with clean water. Check for missed spots and repeat if needed. Let the floor dry completely before parking inside.
## Frequently Asked Questions
