After all the , shall we say talk from Dave Liohowa a few months ago, (forgive me if i,v mispelt name) and his excellent ideas on rug cleaning ,I did try, succesfully this exact method using the cimex , the results where great.
the one downfall , They do take some drying and unless you have the right facilities I find it difficult to find a way round it......... but do love the method.
