Apparatus and method are provided for washing apparatuses in use of remedial tubing. A cylindrical housing has a fluid expansion chamber with fluid passageways communicating between the housing and the chamber. A turbulating sleeve freely rotates relative to the housing. Compression ports permit fluid to be transmitted through the housing, the passageways and into the chamber for injection through the ports to activate rotary motion of the sleeve for turbulizing washing action. A second housing is provided on the apparatus having normally closed wash ports which are angularly directed toward the remedial tubing and rearwardly relative to the apparatus. The wash ports are normally closed and may be opened, selectively, and when open, fluid flow through the apparatus is directed only through the rearwardly directed wash ports to drive particulate matter impacted exterior of the tubing and rearwardly of the apparatus from the apparatus.
