To try and further clarify my earlier post, and question.
The carpet is direct glue down., on concrete. It is not a stain, but recurring soiling. Area becoming soiled by something still in the carpet.
I have cleaned this carpet several times, using only VLM , utilizeing absorbant bonnets, . Microfiber, glads, bonnet pro wool pro etc.
And , using Rick's method(I think correctly) to prevent that stubborn spot.
I have not been there in a while. I plan on stopping by , and giving it a refresh clean. It is really not a large area.
