after my car gets dirty inside i do a full detail makes me feel fresh like a new hair cut . use a cloth soak it in the soapy water and rub everthing door panels, dash, console, etc, etc. then dry a old towel works great. i  then shampoo my carpeting the ghetto way with a shop vac, a bucket of soapy water(landry detergent) and a big brush.
brush the carpet and vacuum itll bring the color back and make it look new do it on a hot day and leave the windows open until it drys. through a bounce sheet under the seat. the car will smell better then most proffesional detail shops if u dont soak the carpet/seats too much and u let it dry without putting the windows up right away.
