Not only are its fumes unhealthy to breathe, she said, but it's bad for some surfaces.
Some surfaces could not be removed, because, as do many 1970s buildings, the hotel contains asbestos.
But a 2006 study found that avian influenza seemed particularly hardy, surviving as long as six days on some surfaces.
The big tires can roar a bit on some surfaces, but there's never been a better all-round sports car.
Some surfaces hold up badly and crack under the pressure of "high heels or heavy rolling objects".
Some surfaces and colors are better than others, but it is clearly speed and the ensemble effect that count.
Some surfaces knit together in nervous, quavering strokes of fleshy pink, orange and white, as if painted with water reflections in mind.
In his compositions of high-color squares and rectangles set edge-to-edge between horizontal bands, the geometric elements vary in size; the supporting bands are unevenly spaced; some surfaces are matte, others brushy.
Last year, Dr. Hartmann of the Planetary Science Institute in Tucson and eight colleagues at Cornell, the United States Geological Survey and other institutions reported that Mars was apparently alive geologically, based on the freshness of some surfaces.
The scientists can further control the flow of liquids by coating some surfaces with hydrophobic substances -- essentially oily substances that repel water -- while coating others with a water-attracting layer.
Mr Booker says the extra slipperiness cuts fuel consumption by around 1%, so that the coating treatment pays for itself within a few months.There may also be a way to cut aircraft drag by making some surfaces less slippery.
