Do the Carpet Cleaning Microsponges work on all stains?
With stain removal, it’s very difficult to say a definite “yes” or “no”. In fact, it’s almost impossible. It depends on the age of the stain, whether it’s been washed yet, the material etc. etc. We can only advise that you try following all instructions, which generally includes doing a patch test – unfortunately we cannot 100% guarantee any specific stain to be removed.
