To effectively kill lawn weeds without harming the grass, you can use selective herbicides that target specific types of weeds while leaving the grass unharmed.

I used a dandelion bar this year because I couldn't find any 2,4 D weed and feed in my city anymore (maybe a good thing). Anyhow, I went with the weed bar and dragged it around my lawn twice this year.

That it is a target weed-killer describes why herbicide can be sprayed in a lawn and only kill the weeds. Herbicides have active and inert ingredients, with some of the former controlling specific weeds and nothing else. Active ingredients function effectively when they leave minimal or no impacts, excluding their targets, on the environment and its animal, people and plant occupants.
Boiling Water I've never tried boiling water but I suspect that this will only kill the leaves leaving the root intact. If you don't kill the root the weed will re-grow. The solution will depend on whether you are treating broadleaf weeds (Dandelion) or grassy weeds. I would recommend products like Ortho Weed-B-Gone which comes in different types. You can spray directly on the weed without damaging the grass. Or you can use a spreader to evenly spread granular weed killer on your lawn. I think the reason some products are a combination of weed killer and fertilizer is that the fertilizer helps promote a healthier, fuller lawn which in turn chokes out weeds.
