for domestic use, I have been using (ultimate master on domestic carpets in small doses after pre spraying with AMtech premium carpet cleaner) I do get good results.
Amtech premium is mostly diluted STPP ( sodium tripolyphosphate )
Ultimate master also looks to contain about 30% STPP ( probably more concentrate than the amtech premium ) along other ingredients likely to be beneficial in a prespray .
You could just prespray with the ultimate master from your tank and then dilute further if you want to keep it in the rince .
but you may just find it convenient to use the amtech in your sprayer .
Pure clean is likely also mainly STPP , i'v loosely worked out that pureclean will be 3 to 4 times more concentrate than the amtech liquid so about 2 to 3 times more economical to use .
