Deep cleaning is different from regular cleaning or spring cleaning because it reaches the deep grime and dirt in your home and it includes spaces that are not usually covered in regularly scheduled cleaning service. For example, deep cleaning in your bathroom, in addition to covering what included in regular cleaning service, might include cleaning the inside and tops of the cupboards, cleaning the medicine cabinet, cleaning underneath and behind the sink and toilet and using professional limescale remover to remove all built up deposits from all taps, tiles and the shower head.
