The invention, an apparatus for cleaning surfaces such as windows, connects to a water source, and uses a portable cylindrical deionized water unit, a garden hose, a replaceable ion exchange resin cartridge, a brush pole system, and a second hose. The cylindrical deionized water unit has an inlet opening, an outlet opening, first and second separate interior chambers; and a valve with first and second positions. The valve at the first position directs water flow through the inlet opening into the first chamber and out through the outlet opening. The valve at the second position directs the water flow through the second chamber and out through the outlet opening. A garden hose connects the inlet opening to the water source. A replaceable ion exchange resin cartridge fits into the second chamber. The brush pole system uses: a hollow pole with an inlet portal, an outlet portal, and a brush. A second hose with a first end that connects to the outlet opening of the cylindrical deionized water unit; and the second hose with a second end connects to the inlet portal of the hollow pole.
