HG air pressure cleaner removes dust and other loose dirt from all hard-to-reach cracks and holes where a normal duster or hoover cannot reach or would have no effect, or could cause damage. It is ideal for cleaning, for example, keyboards, grilles and other (ventilation) openings of computers and televisions, air vents in cars or the shaver head(s). In addition, this product is also excellent for safely cleaning surfaces that should basically not be touched, such as lenses, computer circuit boards and the like.
