The present invention concerns a method for increasing the duration of household use of a sponge (1) comprising the following steps: a) Introducing a support (2), mounted on at least three springs (3) in the non-compressed position, into a container (4) comprising a cover (5), said support (2) comprising a top surface (6) and a bottom surface (7), b) Pouring a composition (8) containing more than 99% by weight of a household vinegar solution and less than 1% by weight of eucalyptus essential oil into said container (4), the level of said composition (8) being lower than the bottom surface (7) of said support (2) when the springs are in the non-compressed position, c) Running said composition (8) under the bottom surface (7) of said support (2) when the springs are in the non-compressed position, the level of said composition (8) being lower than said bottom surface (7) of said support (2), d) Slowly lowering the support (2) by applying pressure vertically towards the bottom of the container (4), said pressure being directed towards the centre of gravity of said support (2) in order to submerge the top surface (6) of said support in said composition (8), e) Slowly raising the support (2) by gradually releasing the pressure, such that a thin liquid layer (9) of the composition (8) from step b) covers the top surface (6) of the support (2), f) Positioning the cellulose surface of the sponge (1) on the top part (6) of the support (2) in order for the thin liquid layer of the composition (8) to be absorbed by capillary action, g) Turning over the sponge (1) on the top part (6) of the support (2), such that the composition (8) spreads by gravity through the sponge (1), h) Closing the cover (5) of the container (4).La présente invention concerne un procédé pour augmenter la durée d'utilisation ménagère d'une éponge (1) comprenant les étapes suivantes : a) Introduction d'un support (2) monté sur au-moins trois ressorts (3) en position non comprimée, dans un récipient (4) co
