| first off what type of carpet is it? is this carpet in an area by a couch or chair?
reason i ask is...certain types of carpets wear differently, so if its a grade that does and its close to a chair or a place were there is constant movement...what your seeing maybe just wear and not soil load
but need to know more answers before i can give a better suggestion
DIY really do lack the power to do a great job..."steam cleaners" although named steam do not produce enough heat to really break the soil loose from the carpets...
when in doubt a professional cleaner may be able to help |
