Once, I had read somewhere (an issue of Consumer Reports???) that 96% of carpet cleaning services cause more damage to carpeting than if it were not cleaned at all. This means that only 4% or 4 out of 100 carpet cleaners actually improved the carpet’s health and appearance and quality levels. Improving the appearance is very easy for a short time. You could simply scrub the carpeting with a small shampoo machine and some dish wash soap...
