Just scored a new pressure washer - what should I blast first?

Hey Tool Discount Club fam! Just unboxed my new Greenworks 3000 PSI pressure washer and I'm STOKED. Got it on that flash sale last week - couldn't resist. This thing looks meaner than my ex's lawyer. Already assembled it in the driveway and my neighbors are giving me that 'what's he gonna break first' look. What should I tackle? My deck looks like it hosted a mud wrestling tournament, but maybe I should start smaller? First impressions: the wand feels solid, hose is longer than I expected. Anyone else running this model?

Start with your driveway or patio - flat surfaces. Don't be that guy who strips the paint off his siding because he used the 15-degree tip instead of the 40. Seen it happen. Check your PSI against the surface material. Concrete can handle the heat, wood needs the wide fan tip and keep it moving. And for god's sake wear shoes - not flip flops. That spray will peel skin like a pressure washer peels grime.

Nice score Betty! I'm still saving up for one... My boss let me use his commercial unit last month to clean our trailer and I accidentally blew a hole in a plastic storage bin lol. Maybe practice on something that won't matter? Like your garbage cans or lawn furniture? Also does it have that quick connect thing for soap? My buddy's does and he says it's clutch for pre-treating.

Steve - always with the safety first! Good call on the shoes, I was totally gonna wear sandals. It came with like 5 different tips so I'll definitely start with the widest one. Matt - YES it has the soap injector! Already filled it with some concrete cleaner. Gonna hit the driveway first like Steve said, then maybe the fence if I don't destroy anything. Thanks y'all! Will post before/after pics if I don't flood my basement somehow.
