Most people winterize their sprinkler system without thinking twice about it, but the grill and outdoor kitchen that sat outside all summer often gets ignored until spring. Whether you've got a full outdoor kitchen or a single freestanding grill, a little prep before the cold sets in goes a long way.
Yes — this is the step people skip most, and it's the one that matters most. Grease and food residue left on a grill over the winter has months to bake on, attract pests, and cause rust, especially on cast iron components. It's a lot easier to clean a grill before a long stretch of sitting unused than after. If you're shutting your grill down for the season, get it cleaned first rather than last.
Built-in components have a few extra considerations:
In Colorado, the safest bet is before the first hard freeze, which can arrive earlier than people expect along the Front Range. If you know you're done grilling for the season, don't wait for the first snow — get it cleaned and covered while the weather's still cooperative to work in.
Get it cleaned first — it's a lot easier than dealing with baked-on grease in the spring.
