The instructions for our Weber gas grill would have us lavish more care on it than we do on our car, which isn’t actually saying much. Nonetheless, once a year I gotta clean the crud out, whether it needs it or not, because not even I believe heat kills that stuff.
Used to be, that was a thoroughly disgusting job of hand-scraping carbonized gunk and scrubbing gooey muck in cramped quarters. Having acquired a pressure washer, cleaning the grill is almost enough fun that I might do it more often. It even gets the mildew (or whatever that schmutz might be) off the wood handles & platforms, which I would have bet was impossible.
However, if you’re even a teensy bit fussier than we are about the looks of your castle, you might want to not lay the grates & “flavorizer bars” on the driveway to blast ‘em clean. Turns out that the overspray strips the grunge right out of the top layer of asphalt, leaving a white trail behind.
Looks a lot like those Nasca peteroglyphs, doesn’t it?
The pressure washer does a great job on the white resin plastic chairs, too, which go from really grubby to chalk-white in one pass.
Can’t imagine how I got along without it…
Memo to Self: Next time, use the sawhorses.
