A method and apparatus for cleaning exterior surfaces, particularly aircraft exteriors, which method and apparatus applies cleaning solution to a soiled surface, scours the surface, squeegees the contaminated solution from the surface and evacuates it through a vacuum manifold for collection and environmentally appropriate disposal. Applicant's method and apparatus are designed principally to alleviate the problem of toxic run-off and ground water pollution as attends present-day wash-rack or bucket and brush type washing operations. Applicant's method and apparatus are also beneficial from a convenience standpoint, as an aircraft may be cleaned in any location without the necessity of removing the aircraft to a maintenance facility. Applicant's method and apparatus are also useful for other exterior surfaces, such as for cleaning skyscraper surfaces. |
