Outdoor pizza ovens and grills are the heart of backyard gatherings, summer cookouts, and family pizza nights. But after countless sizzling steaks, bubbling pizzas, and grilled veggies, your cooking setup can become coated in layers of grease, soot, ash, and food debris. 😬
Many homeowners wonder: Can I pressure wash my outdoor pizza oven or grill safely? The short answer is yes—with caution. Done properly, pressure washing can be a fast and effective way to restore your equipment’s shine and hygiene. Done wrong, it can damage surfaces, push water into delicate components, or leave behind streaks and messes. 😵
This guide walks you through the best practices for pressure washing your outdoor grill or pizza oven, including which materials can handle it, how to prep, and what to avoid.

A good pressure wash can:

✅ Reduce rust buildup
✅ Extend the lifespan of your investment
It’s especially helpful before and after the grilling season. 🧽🔥

🛠️ How to Pressure Wash a Grill
1️⃣ Disconnect and Disassemble
Turn off the gas and disconnect propane or natural gas lines. Remove grates, flavorizer bars, burners, and other removable parts.
Place smaller parts on a tarp for separate cleaning. 🛑🔥
2️⃣ Apply Degreaser or Cleaning Solution
Use a grill-safe degreaser or 1:1 vinegar and water. Let it sit for 10–15 minutes to loosen grime. Scrub stubborn areas with a grill brush.
3️⃣ Spray Using Low Pressure
Use a 40° tip and hold the nozzle about 2 feet from the surface. Spray from top to bottom:
- Inside the hood
- Cooking chamber
- Exterior panels
- Bottom tray or grease pan
Avoid spraying directly into gas ports or electric igniters. Use a towel to block them if needed.
4️⃣ Rinse and Dry
Rinse everything thoroughly. Use towels or let air dry in the sun. Reassemble only when all components are fully dry to prevent rust or gas issues.
🪵 How to Pressure Wash a Pizza Oven
Brick or stone ovens:
- Remove ashes, soot, and pizza stone if possible
- Sweep out debris
- Use low pressure (25°–40° tip)
- Rinse gently without soaking mortar
- Avoid aiming directly into chimney flue
Ceramic or clay ovens:
Use extreme caution. Low-pressure rinsing is fine, but never soak the structure—it may crack during reheating due to trapped moisture.
Metal pizza ovens:
These can generally handle pressure washing, especially if they’re coated or stainless steel. Avoid openings and seams.
🌞 Post-Cleaning Tips
- Let all equipment dry completely before covering or using again
- Season cooking grates with oil after drying
- Dispose of greasy runoff responsibly—don’t let it enter storm drains
- Consider sealing bricks or stone with an outdoor-safe sealant to reduce future buildup
🚫 What Not to Do
- Don’t pressure wash an electric or pellet grill
- Don’t spray into burner tubes or igniters
- Don’t use bleach or harsh chemicals on food-contact surfaces
- Don’t use maximum pressure—it may strip paint or warp parts
- Don’t reassemble until parts are 100% dry
Water left in gas lines or internal chambers can cause malfunctions or dangerous flare-ups. ❗
🔧 Maintenance Schedule
To keep things clean without overdoing it:
| Task | Frequency |
|---|---|
| Spot clean grates | After each use |
| Deep clean grates & interior | Monthly during season |
| Pressure wash full grill | 1–2 times per year |
| Clean pizza oven exterior | As needed or seasonally |
🔥 Final Thoughts
Pressure washing your grill or pizza oven can save hours of scrubbing and restore your cooking gear to its original glory. With the right approach, you can safely remove years of grime, grease, and soot.
Just remember: low pressure, thorough prep, and drying are key. When in doubt, hand-clean sensitive components and stick to pressure washing only the sturdy exterior parts.
So get ready to fire it up—clean, shiny, and ready to serve! 🍕🔥🧽
