De-icing is defined as removal of existing snow, ice or frost from a roadway, airport runway, roof, or other surface. It includes both mechanical means, such as plowing, vacuuming or scraping, and chemical means, such as application of salt or other ice-melting chemicals.
Roof cleaning is the process of removing algae, [1] mold, mildew, lichen and moss from roofs. [2] Also cleaning oxidation on metal roofs. Cleaning can extend the duration of a roof's ability to function. [2] Algae and other types of build-up often form on the north and west parts of roofs that are shaded or receive less sun, and can reduce a ...

A key advantage of this method over traditional approaches is the ability to deep clean grouted areas (e.g. wall, counter and floor tile) preventing buildup of soil and bacteria in grout lines. Application of a cleaning solution followed by pressurized rinsing and vacuuming removes soil more effectively than methods that rely solely on ...

Anti-icing is the application of chemicals that not only de-ice but also remain on a surface and continue to delay the reformation of ice for a certain period of time, or prevent adhesion of ice to make mechanical removal easier.
The danger of mechanical cleaning is the potential for the surface to break or become scratched with a tool. Dusting is used when dirt is not strongly adhered to the surface of the ceramic and is carried out by either a brush or a soft cloth. Large ceramic vessels are cleaned with a delicate vacuum cleaner with a soft, muslin-covered head ...
Domestically they used it for statuary and roof tiles. The Etruscans used terracotta for roof tiles, encased beams, and enclosed brick walls with it. The Roman terracotta innovation was the underfloor or hypocaust heating system that they used for their bath houses. [8] Medieval European architecture did not expand terracotta use beyond the ...
