Passengers would occasionally discover soap mixed with toilet bowl cleaner, spit and even urine. I have finally found one with a sealed soap reservoir, and every time the contractor changes the soap, he also changes the dispensing mechanism. At the new Denver airport, the restroom walls will be covered with ceramic tiles, the floors will be terrazzo and the modesty panels will be made of stainless steel, says Austin. But stainless steel is easiest to take care of. When it is cut into with a sharp object, the steel surface reacts to oxygen and other elements in the air and is what we call self-healing.
People even color in the grout lines between the ceramic tiles.
It's amazing that they have the time and tools with them to do this kind of thing. Tampa's Smith is not so convinced about steel. The dedicated vandal can scratch it with a key. Now we're trying a stainless steel with a bubble surface. But we know that the vandal research committee stays only one step behind us.
