The best product for fighting weeds in my opinion is MSMA which you mix as a spray. This product not only kills broadleaved weeds, but it will also kill most grassy type of weeds as well. This product works especially well on Bermuda grass. As a note though, it may yellow the Bermuda but it won't kill it. Read the bottle if you have another type of grass as it may not be suitable on other grasses. For the better part, I've found that it kills almost any type of weed, broadleaved or a grass type. It works best on a warm, sunny day.
