Febreeze works really well: it's molecules encapsulate other ones somehow...

The product's active ingredient is cyclodextrin, which is a type of modified starch having a shape similar to a donut. The manufacturer claims that molecules of this starch bind hydrophobic compounds within the donut shape, thus retaining malodorous molecules so that they are no longer detected as a scent.
Cyclodextrins are able to form host-guest complexes with hydrophobic molecules given the unique nature imparted by their structure. As a result these molecules have found a number of applications in a wide range of fields. Other than the above mentioned pharmaceutical applications for drug release, cyclodextrins can be employed in environmental protection: these molecules can effectively immobilise inside their rings toxic compounds, like trichloroethane or heavy metals, or can form complexes with stable substances, like trichlorfon (an organophosphorus insecticide) or sewage sludge, enhancing their decomposition.
