This one has me stumped. I am gonna try and condense this problem as much as possible.
Moved into our house in 1997. Replaced the carpet in 3 rooms in 2001. Within a year, a dark black stain started to appear around the perimeter of all 3 rooms. Slowly got worse to the point that I am hand scrubbing it with bissell cleaner and sucking it up with the little green machine. Comes up relatively easy. Looks like coffee in the tank that holds the sucked up water.
My wife runs an emaculate household. Vacuums and dusts atleast twice a week. Naturally, I am curious as to what is causing it so I can eliminate the problem while I have it clean.
Heat is baseboard. Walls are drywall.
Someone suggested that if the base of the drywall wasn't caulked before putting on the baseboard, that perhaps dirt is falling through the wall. No idea on the merit of it.
The rooms with the original carpet also have the stains now but not as noticeable since the carpet is older and darker. I do not remember them there when we moved in. Even used a carpet cleaner before moving furniture in and I would think I would have noticed it.
Thoughts? What are your thoughts on the type of vaccuum cleaner causing it? We have used the same vaccuum since we moved into this house.
Attached is a pic...it doesn't do it justice but you will get the idea.
