How do I QUICKLY get stains out of a white shirt?

Question:I have an all white shirt that has quite a few dirt stains. I am a filmmaker and need this shirt clean in a few hours so I don't have time to run to the store to get cleaning supplys. Is there anyway I can get this clean with products that I already have? What about baking soda or vinigar?

Perfect your idea, it is exactly what I use on everything in and around my house to laundry stains and odors to residues from detergents to deodorants, I can give you some ideas here for removing old and new stains with vinegar and baking soda
There are so many benefits to be reaped by adding 1 cup white vinegar to your washer's rinse cycle that it's surprising that you don't find it prominently mentioned inside the owner's manual of every washing machine sold. Here are the main ones:
A single cup of vinegar will kill off any bacteria that may be present in your wash load, especially if it includes cloth diapers and the like.

A cup of vinegar will keep your clothes coming out of the wash soft and smelling fresh -- so you can kiss your fabric-softening liquids and sheets good-bye (unless, of course, you happen to like your clothes smelling of heavy perfumes).

A cup of vinegar will brighten small loads of white clothes.

Added to the last rinse, a cup of vinegar will keep your clothes lint- and static-free.

Adding a cupful of vinegar to the last rinse will set the color of your newly dyed fabrics
Brighten your loads

Why waste money on that costly all-color bleach when you can get the same results using vinegar? Just add 1/2 cup white vinegar to your machine's wash cycle to brighten up the colors in each load.

Pat away water-soluble stains

You can lift out many water-soluble stains -- including beer, orange and other fruit juices, black coffee or tea, and vomit --from your cotton-blend clothing by patting the spot with a cloth or towel moistened with undiluted white vinegar just before placing it in the wash. For large stains, you may want to soak the garment overnight in a solution of 3 parts vinegar to 1 part cold water before washing.

Unset old stains

Older, set-in stains will often come out in the wash after being pretreated with a solution of 3 tablespoons white vinegar and 2 tablespoons liquid detergent in 1 quart (1 liter) warm water. Rub the solution into the stain, then blot it dry before washing.
Sponge out serious stains

Cola, hair dye, ketchup, and wine stains on washable cotton blends should be treated as soon as possible (that is, within 24 hours). Sponge the area with undiluted vinegar and launder immediately afterward. For severe stains, add 1-2 cups vinegar to the wash cycle as well.

Pretreat perspiration stains

Want to see those sweat marks disappear from shirts and other garments? Just pour a bit of vinegar directly onto the stain, and rub it into the fabric before placing the item in the wash. You can also remove deodorant stains from your washable shirts and blouses by gently rubbing the spot with undiluted vinegar before laundering.

Good Luck !
