  • hard and soft surfaces e.g. kitchen tops, tiles, carpets, upholstery, windows, including car windscreens, etc
  • Fabrics need to be cleaned from time to time depending on the perception of the cleanliness of the consumers.
  • washing a fabric causes fabric damage.

Due to reduced frequency of fabric washing the weariness will also be less and the fabrics will become long lasting.
