Internal Car Odors

Hello Gentlemen, My husband and I are EXTREMELY illergic to the sorts of scents that are commonly found in cars. This includes new car smell (formaldehyde and such), cigarette smoke residue, perfume/cologne inflicted by humans, car deodorizers applied by rental companies and carwashes… I’m sure you get the picture. We have great difficulty being in cars of this nature. Renting a car is nearly imposible for us.

This extremely long and probably unnecessary preamble (never thought I’d have the chance to throw that word in anywhere) leads up to… How can we eliminate smells that have permeated car interiors without adding more crap. We’ve tried ozone but understand that it should be used with care. We don’t know how much or how long it should be applied.
