This simple, inexpensive cleaning tool consisting of a partially flattened tube with a spade or wedge shape guiding tip, and holes, slots or nozzles on one or both flattened sides can be inserted between heat exchangers or radiators as used on motor vehicles or can be used in other limited access areas. The tube can be connected to a pressurized liquid or gas source for cleaning or coating in confined spaces such as the stacked heat exchangers, radiators, as described above, but also electric motors or electrical panels, appliances, computers and so forth, eliminating the need for time consuming and expensive disassembly. The device can be made of a variety of materials, and in a variety of lengths and widths depending on pressure needed, type of equipment being cleaned and fluids or gases being used. Equipment cleaned in this manner can be returned to optimal service quickly and cheaply. This device creates a new family of simple tools much as hammers, screw drivers, blow guns or wrenches each represents a family of tools. Each of these families may be made in different sizes or from different materials as necessary for the job being done. The same is true for this new device.
