So I'm new to the forum, im from maryland im a 46 year old male I'm not a carpet cleaner I actually work at my states airport deicing aircraft, the reason I came to this forum today is I tried to clean my bedroom carpet using a TMF product called black label pre-spray,I followed the instructions giving to me by a carpet cleaning tech via reddit and such, I followed his instructions and afterwards my carpet is brown,more brown than usual its my fault though not sure what I did wrong maybe the Pre spray I'm using is to high in PH not sure?
