Dirt is not only dust. Dirt also consists of stains, grease and oil build
up on carpets, sofas, chairs and floors. Oily dirt also concentrates on
matresses caused by the skin and dandruff that people lose everyday.

best. It is necessary to wash with water and with cleansing agents
that have been tested and proven.
