As already said, get a cover. I believe it’s required to keep the warranty in full force I believe.
I use a mapp torch, along with Rutland starter cubes, it works beautifully.
Eventually, you’ll want some Zep 505 cleaner, it’s the best for exterior grill cleaning. For interior, I recommend a shop vac with a drywall filter.
Get plenty of teak conditioner, the northern weather wreaks havoc on teak.
You’re gonna love your grill, many pics are required
