Suck up most of the liquid with a towel. Don't rub the stain in, just press lightly straight on the stain. Afterwards you can pour salt on it to suck up the rest. If you brush off the salt and the stian is still there, you can moisten the stain in cold water and repeat the salt process. Next time you wash the garment you can put stain remover (like lemon soap or dish soap) on the stain before putting it in the machine.
