Let’s be honest: the first time I picked up a jet washer, I thought it’d be a walk in the park. Point, spray, admire the sparkle, maybe pat myself on the back. But no — turns out there’s a bit of a knack to it. You don’t just blast dirt and hope for the best. You’ve got to read the surface, think about angles, and yeah, sometimes you’ve got to step back and admit defeat before you strip the paint off your nan’s garden fence.
