a) providing an apparatus in an environment including a surface comprising a permeable material having disposed thereon a malodor containing compound selected from the group consisting of: amine-containing compound and thiol-containing compound, wherein the apparatus includes a volatile material having a volatile carbonyl containing compound having a vapor pressure of at least 0.025 torr at 25 degrees Celsius; and
b) exposing the volatile material to the environment without aerosol means such that the volatile carbonyl containing compound vaporizes from the apparatus and deposits on at least a portion of the surface;
wherein the carbonyl containing compound undergoes a nucleophilic addition in the presence of the malodor containing compound, and
wherein exposing the volatile material to the environment does not comprise emitting a non-volatile compound.
