I made the goo about 3 - 4 weeks ago in my processor before I got my TM. Have been using it all this time and found it worked well, but have noticed just recently that some of our clothes are starting to look a little 'dull'. Probably because store bought detergent has optical whiteners and brighteners that this home made stuff hasn't. I therefore have started to use it less, inbetween using store bought detergent.
