9 Essential Outdoor Kitchen Maintenance Tips for a Long-Lasting, Functional Space

The party is booked, guests have RSVP’d, and the weather is warming up nicely. You stroll out back to pull the covers off of your outdoor kitchen components for the first time in a while.

Mildewed seating, stained counters, a sink that stinks, and a grimy grill. The cement patio itself is streaked and dingy, and the cabinets are looking worse for wear. 

Severe weather events and unpredictable temperatures are a fact of modern life. If you don’t want to postpone your party plans, it’s time to get serious about outdoor kitchen maintenance. 

How to keep an outdoor kitchen clean

Before we get into the nitty-gritty of annual inspection and deep cleaning, here are some general cleaning tips for new outdoor kitchen owners. Much of this will act as preventative maintenance, shortening the time and cost associated with kitchen upkeep.

• Keep plants and foliage trimmed back to reduce hazards and debris
• Place mats at entry points to help keep patios and porches cleaner
• Wipe down surfaces daily when the kitchen is in regular use
• Ensure trash cans have tight-fitting lids so as not to attract pests
• Keep utensils, seasonings, and other supplies in a sealed, waterproof storage container
• Invest in covers for appliances and furniture
• Add warranties, user guides, and manuals for all equipment to a dedicated folder for easy access
• Use products that are formulated for outdoor furniture and equipment, where possible
• Wipe down seating cushions with mild, diluted detergent
• Clean grills after every use

Outdoor kitchen maintenance checklist

Whether you’ve fallen behind, had a rough winter, or are just looking forward to the best summer ever, here’s how to get your outdoor kitchen in tip-top shape.

1. Deep clean grills and ovens

Don’t rush through this one–a few times a year, perform a detailed deep cleaning on grills, pizza ovens, and regular ovens. 

Intermittent serious scrubbing reduces the need for abrasive cleaners throughout the busiest season/s. It can extend the life of your appliances and prevent residue that never seems to budge.

2. Inspect appliances

At least twice a year, turn off power sources and consult your manuals. Follow the manufacturer’s inspection instructions–they can show you how and where to check for leaks and corrosion.

You should also visually inspect connections to ensure they’re not damaged and test any safety features.

3. Check utilities

Gas, electrical, and plumbing require inspection, too, but you may want a professional on hand. If you use gas, look at the lines to see that they’re in good shape and check/test the shut off valves.

An electrician can verify that GFCIs and circuit breakers are functioning properly. A plumber can ensure the water pressure is in the recommended range and there are no drainage issues.

4. Care for countertops

Cover counters when not in use for long periods, no matter the material. Natural stone countertops like granite should be resealed every one to three years, depending on climate and frequency of use. 

5. Replace worn or damaged components

Warped cabinets, waterlogged surfaces, and scuffed up countertops just won’t do. In fact, once one area is damaged, it can spread. Prevent having to make a larger investment in the future by replacing things that are broken or worn beyond repair. 

6. Look out for pests

Wasps, certain types of bees, ants, mosquitoes, and termites can all cause damage, create a nuisance, or contaminate food. You’ll always have insects hanging around outside, but discourage them from making your home their home.

Squirrels, mice, chipmunks, and raccoons can also pose a danger, particularly by gnawing on wiring or damaging other equipment parts. This is why regular inspection is key–look for signs of chewing and bits of refuse used for nesting.

7. Protect cabinetry

Proper drainage and overhead coverage like pergolas and awnings are just the beginning when it comes to preserving outdoor cabinets. 

The use of waterproof covers and regular resealing can help as well, but outdoor-rated materials and weatherproof gaskets are the way to go. Keep reading for more information on the proper cabinets for outdoor kitchens.

8. Keep it covered

Speaking of covers, these should be inspected too, especially if there’s been evidence of pests. Covers should be weatherproof with no tears or minimal wear. 

Covers for appliances, grills, cabinets, and seating aren’t just for winter, either. Hot, direct sunlight, frequent rains, and strong winds can all compromise or otherwise damage your space.

9. Pressure washing

Pressure wash outdoor kitchen “floors” a few times a year. Concrete and pressure-treated wood can become prone to mold and mildew, especially if you’ve had drainage problems or a lot of wet weather.

Ensure the proper PSI for washing as some materials can be prone to noticeable etching or damage if it’s too high.

Custom outdoor kitchen cabinets take tasks off your to-do list

Choosing weather-resistant, low-maintenance cabinets does more for the life of your outdoor kitchen than you might assume. These consoles serve as the foundation of your outdoor kitchen, supporting and helping to protect your appliances and equipment. 

They can even be fabricated from composite and recycled materials for sustainability. Learn more about the expansive design options available for outdoor-rated kitchen cabinets and book a free consultation.

Outdoor kitchen maintenance FAQ

Here are answers to some of your most popular questions about outdoor kitchen maintenance.

How do you weatherproof an outdoor kitchen?

Begin with the right materials. All equipment should be approved or suitable for outdoor use. Secure, properly fitting covers offer basic protection when the kitchen’s not in use. It’s also a good idea to add a roof or pergola for protection from the elements, including harsh UV rays. 

What is the most durable outdoor kitchen material?

Stainless steel is a popular, long-lasting choice for appliances and cabinets. Weatherproof composites like HDPE are also incredibly durable. Many kitchen owners choose weatherproof consoles with custom-built-ins for stainless steel for appliances and grills. 

How long do outdoor kitchens last?

Your climate, frequency of use, maintenance habits, and other conditions will determine this. Generally speaking, however, a good-quality, well-maintained outdoor kitchen can typically last 20 years.

What does every outdoor kitchen need? 

The basics of an outdoor kitchen begin with a grill, griddle, or stove. From there, a sink, countertop, refrigeration, and seating make it a real al fresco kitchen. Extras like a bar, pizza oven, cooktop, and décor take it to the next level.
