How to Maintain an Outdoor Kitchen, by Climate and Season
Rinse your outdoor kitchen with fresh water weekly, wipe down surfaces and check hardware monthly, and do a deeper clean once a quarter. Then adjust that baseline for where you live: freeze-thaw climates need the plumbing handled before the first hard freeze, high-UV climates need the finish protected from sun rather than from moisture, and humid climates need airflow and drying more than they need cleaning products.
