There’s a long list of reasons to own a good pressure washer. For us car fans, a pressure washer means more effective, efficient car washing – akin to having a coin-operated car wash stall at home. For homeowners, pressure washers offer even more utility, from power-cleaning decks, driveways, and siding, to spraying out gutters and scrubbing down grills.
But no matter what you use your pressure washer for, it’s only as good as the spray gun attached to it. Using a high-performance pressure washer with a sub-par gun is sort of like driving a Porsche on worn-down all-season tires: there’s a performance bottleneck there, and it’s holding you back.
The good news is that, much like those worn-out all-seasons, your pressure washer gun can very easily be upgraded to a better, higher-performance unit. For you home auto detailing aficionados, we’ve already looked at the best foam cannons on the market. Now, it’s time to turn our attention to the best pressure washer guns. The two go hand-in-hand; most – if not all – of the guns on this list ought to be compatible with the majority of foam cannons on the market. But if you’re ever going to maximize your car detailing capabilities at home, both the foam cannon and pressure washer gun have to be of a particular quality, and in tip-top shape.
With that, here are our picks for the best pressure washer guns on the market.
