Not all mouthwashes will help with sore throat. Research shows that commony available mouth wash containing povidone iodine or chlorhexidine is effective in reducing the intensity and duration of the symptoms of sore throat. Iodine based mouthwash is quite effective on certain viruses, bacteria and some fungi as well, however it does make a mess if it splashes on your clothes.
