I seem to have a haunted carpet! There are a few dark stains that I
can't get rid of. They are fairly large, and look like a liquid stain
in pattern. We have cleaned it multiple times and they reappear-like
When you go over the stains, it appears clean, but as it dries, they
come back. I am assuming it's something that's being wicked up by the
carpet as it dries; however CONSTANT repetitive cleaning doesn't seem
to diminish the effect. My girlfriend thinks it may be the adhesive
from the carpet backing that is used to adhere the fibers to the base,
but I can't imagine that it would cause staining of this color (like
coffee or oil). I have even tried soaking a small section with hot
water and extracting to see if there's any difference, but no.
Has anyone ever experienced this?
