The present invention relates to a method and a device to evaporate low volatility active substances or ingredients from a liquid solution contained in a reservoir (2). The device comprises at least one liquid retaining support and dispensing means (14) arranged in a casing (1) at a distance and in a suitable position for dispensing doses of said liquid solution on said support by means of a push-button (6). The device further has a timer adapted to allow the operation of said dispensing means in selected time periods, said time periods being greater than the time necessary for evaporating most of the solvent and active ingredient from the support.
