If it is the cfr machine that recycles the cleaning solution then I would only use cfr chemicals, it's not the same as other portables which are generic
I would think WOCs microsplitter would be ok but cfr do a whole range of more specialised chemicals (deodorisers, enzymes, spotters etc) which are designed with the recycling method in mind.
It might be ok with Mpower and other stuff but if you have gone down the recycling route then I would stick with the whole cfr concept.
