The interior is a good starting point, so the dust and dirt you brush out won't settle on a pristine exterior. Remove any floor mats and give the carpeting and upholstery a good vacuuming. Also vacuum the dash and rear parcel shelf. Move the front seats full fore and aft to get to all the accumulated dirt and loose change. If the carpets are clean except for a minor stain or two, use a foaming cleaner to get them out. Saturate the stain with cleaner, working it in with a damp sponge. Let it sit awhile and then blot it out with paper towels or a dry cotton cloth. Repeat if necessary, and then go over the area with a damp sponge before final blotting. Don't oversaturate the carpet and risk getting mildew.

You can repair burns and holes in your carpet by cutting out the offending area with a razor blade or scissors. Then cut a similar-size piece from a hidden spot, such as underneath the seat, and cement it in place using a water-resistant adhesive. Blend in the repair by brushing the nap.

Wash the floor mats, if they're rubber, and apply a dressing that does not leave a slippery finish, for obvious reasons.

Clean interior hard surfaces with a damp cloth and a mild all-purpose cleaner such as Simple Green, diluted about 10:1. If you have vinyl-covered seats, use a conditioner made for that material. Avoid products that give a high-gloss, slippery surface, so passengers won't feel like they're on a roller coaster. If you have leather upholstery, dress the surfaces with a leather conditioner. Never use a vinyl product on leather.

This is just a little bit of how to their is alot that can go for detailing your car.
