Dirt is unclean matter, especially when in contact with a person's clothes, skin or possessions. In such case they are said to become dirty. Common types of dirt include:

Dust: a general powder of organic or mineral matter

Filth: foul matter such as excrement

Grime: a black, ingrained dust such as soot

Soil: the mix of clay, sand, and humus which lies on top of bedrock

Exhibitions and studies

A season of artworks and exhibits on the theme of dirt was sponsored by the Wellcome Trust in 2011. The centrepiece was an exhibition at the Wellcome Collection showing pictures and histories of notable dirt such as the great dust heaps at Euston and King's Cross in the 19th century and the Fresh Kills landfill which was once the world's largest landfill.

Cleaning

When things are dirty they are usually cleaned with solutions like hard surface cleaner and other chemicals solutions; much domestic activity is for this purpose — washing, sweeping and so forth.In a commercial setting, a dirty appearance gives a bad impression. An example of such a place is a restaurant. The dirt in such cases may be classified as temporary, permanent, and deliberate. Temporary dirt is streaks and detritus that may be removed by ordinary daily cleaning. Permanent dirt is ingrained stains or physical damage to an object, which require major renovation to remove. Deliberate dirt is that which results from design decisions such as decor in dirty orange or grunge styling.
