Oklahoma’s outdoor season is long and the cooking is serious — which means your outdoor kitchen accumulates grease, grime, pollen, and weather exposure faster than any indoor appliance. Regular cleaning not only keeps your outdoor kitchen looking great, it extends the life of your appliances, countertops, and cabinetry. Here’s a complete guide to power washing and deep cleaning your outdoor kitchen.
How Often Should You Deep Clean Your Outdoor Kitchen?
Most outdoor kitchens in Oklahoma benefit from a thorough deep clean twice a year — once at the start of outdoor season in spring, and once at the end of the season in fall before winterizing. If you cook frequently, quarterly is better.
Surface-level maintenance — wiping down countertops after each use, cleaning grill grates, and covering appliances when not in use — should happen much more frequently.
Cleaning by Surface Type
Stainless Steel Appliances and Doors
- Use a stainless steel cleaner or a mixture of dish soap and warm water
- Always wipe with the grain of the steel — never against it or in circles
- For heavy grease, a degreaser like Simple Green is safe on stainless
- Finish with a stainless steel polish to restore shine and add a protective layer
- Never use steel wool or abrasive scrubbers — they scratch and can cause rust spots
Concrete and Porcelain Countertops
- Avoid acidic cleaners (vinegar, citrus-based) on concrete — they can etch the surface
- Use a pH-neutral cleaner and a soft brush for routine cleaning
- For sealed concrete, re-seal every 1-2 years to maintain stain resistance
- Porcelain tile is more forgiving — a mild all-purpose cleaner works well for routine maintenance
Stone Veneer and Brick Facades
- A garden hose with a spray nozzle removes loose dirt and pollen effectively
- For deeper cleaning, a low-pressure power washer (under 1,500 PSI) is safe on most stone veneer
- Avoid high-pressure directly on mortar joints — it can dislodge grout over time
- Efflorescence (white mineral deposits) can be removed with a diluted muriatic acid solution — wear gloves and rinse thoroughly
The Grill
- Remove and soak grill grates in hot soapy water — a wire grill brush handles stuck-on carbon
- Clean the inside of the grill box with a grill brush and wipe with a damp cloth
- Clean burner tubes with a soft brush to clear blocked ports
- Wipe the outside of the grill with stainless steel cleaner
- Check the drip tray and empty/clean it — accumulated grease is a fire hazard
Can You Power Wash an Outdoor Kitchen?
Yes, with caution. A pressure washer can be used on stone veneer, concrete pads, and paver surfaces. However, avoid directing a pressure washer at:
- Electrical outlets and GFCI breakers
- Appliance control panels and igniters
- The inside of any appliance
- Mortar joints at close range
Always cover or tape off electrical components before using a pressure washer nearby.
