As far as I know, there are many ways to get rid of weeds, but you have to choose which one is right for you. I know that many gardeners use synthetic products as well as chemicals to control weeds, but I can't say exactly how effective it is. In addition, it is harmful to the health of the body, especially the skin. Even if you use gloves, you are not 100% protected.Personally, I use a trimmer that not only mows the lawn, but also gets rid of weeds. Honestly, it's convenient and the main thing is that it's safe. You can find more information here if you are interested. Let me know about your choice.
