started to clean a 'Next' woolen rug aprox 3m*4m size (2yrs plus age),
was lightly soiled but had small dog urine marks pointed out to customer that these may not be removed completely, started cleaning (std vac, woolsafe prespray, woolsafe extraction) all fine ..suddenly pile started to extract local area ... looking closely backing localy started to break up!! turning to an almost powder! Any answers or other similar experiences welcome... quickly removed local pre spray.. currently awaiting for 'next' to respond we have treatment risk but we have cleaned it by the book!
