Wet sandblasting kits and heads for a pressure cleaner. A wet blast head turns a pressure washer into a blaster by drawing abrasive into the jet. It strips paint, rust and coatings that water alone will not shift, and the water keeps the dust down while it does it.

Match the head and nozzle to your machine - wet blasting wants pressure, and a machine under about 3,000 psi will disappoint. Nozzle orifice sizing matters as much as it does on a turbo. Use a proper blasting media, not builders sand, and wear eye and respiratory protection even though the process is wet. Nozzles wear fast in this job, so buy a spare with the kit.
