The active ingredient in 'weed be gone' is 2, 4-D. Buy it in liquid form in larger containers. Spray it using a hose sprayer when it is calm, and isn't going to rain. The mist from the end of your spray is also lethal to plants and shrubs so be damn careful that you don't get the mist onto things you want to keep. Fleet farm here has it in larger quantities.
2, 4-D kills broad leaf plants. It won't kill crabgrass. It will kill your trees and shrubs and garden if you get it on them.
2, 4-D won't accumulate in your soil. Sunlight breaks it down.
Read the instructions on the 2, 4-D container and follow them. Treat it like it's a toxin to yourself also because it is.

It does work great however. It will kill almost all the weeds in your lawn (crabgrass excluded). If you are looking at your lawn and thinking, "But it's all weeds" don't worry.
I highly recommend using it. (With the above precautions)
