How to get rid of cigarette odor with air purifier ozone machine generator remove smoke smell

Ways to get rid of smoke smell in car or probably in a smoking room as well 1- treat car with shampoo (I used icy clean) 2- lots of hard rubbing on the carpets with a brush and shampoo. 3- wipe every part of the interior surface down with all purpose cleaner. 4- run an ozone generator immediately after cleaning for 45 minutes - I got mine from www.ibreathefreshair.com - repeat this process as many times as needed until the smell is 99% gone -- sometimes I get lucky and clean out all the smell the first try - sometimes I need over 8 tries as the car is so bad. Every auto detailed should use this to make cars smell exceptionally well before giving to the customer. Used car dealerships should use this process to make cars smell new before selling.
