You
may notice some grayish to blackish looking lines around the perimeter
of your room and in some cases underneath doors that have been
closed for an extended period of time. And even in some odder
cases, sometimes in the middle of the room. This is commonly known
as filtration soil.
Filtration
soil is very apparent on lighter carpet. For the most part, it
cannot be removed by normal cleaning. In rooms stained with filtration
soil, EZ Dry uses an internal jet crevice tool for this problem.
This is another feature that separates EZ Dry from its competitors.
If
these lines cannot be removed by the special crevice tool, then
additional treatment may be required at an additional cost. However,
an attempt is made first to rid the markings first at no additional
charge. There are some preventative measures that you can take
to prevent these lines from appearing. |
