An ozonator is a small machine used commonly by detailers to remove strong odors by creating ozone in the vehicle. After using an ozone machine, we must allow the vehicle to air out before driving. We also cannot forget the interior detail! Simply killing off the smells using ozone is not the fix all unfortunately. The interior of the vehicle will also need to be cleaned thoroughly to rid it off the cause of the smell in order to keep it from coming back. For this reason, smell removal can only be done as an add on to an interior detail.
