Ammonia and Ajax? New one for me, seems to be extremely toxic and certainly not environmentally friendly. Many use a combination of vinegar, salt and dish soap. I just use vinegar in a pump sprayer as salt can be extremely corrosive over time.

Yeah it was vinegar, not ammonia, my bad!!

And salt and Ajax. Sorry for any confusion

I use one cup of vinegar, one cup of table salt to two gallons water in a garden sprayer. Saturate the weeds till dipping. Do not use on lawn or in garden will kill everything. Boiling water on weeds in lawn and garden. I did it this morning and the some weeds were already wilted by dusk.
