We have a large potted plant sitting on the carpet in the living room.
Before I could place a deep dish under it, it got watered, and the brown
water made a large brownish stain on the beige carpet. I've tried a
couple of cleaning agents on it, which helped a little but still left a
noticeable stain. Anyone have any suggestions/advice? Thanks.

Go see a carpet shop and get whatever product they use for kool aid and
stains of vegetable origin.
One brand was "Kool Out"
