Matt you are making yourslef look daft mate, if you said "Colliods arent as good as detergents" then you have a constructive argument, but by makeing such a sweeping statement as "they dont work, never did, never will" you just look like you havent got a clue, let me give you an example as to why i know that colliods work
We just finished an office clean, i noticed a square patch that didnt look as good as the rest and couldn't understand why as it had all been cleaned the same, anyway i went to fill up the sprayer and noticed that the measuring cup sat on the side with solution in allready measued out, it turns out that it had not been put in the spray last time, so i filled the sprayer re-applied to the area in question and hey presto clean capret. So if colliods are tap water or only as good as tap water, you will have to explain what happended there.
As i said before i too use detergents so im not biased, i can understand if you have a preference to a particluar prodcut we all do but dont make sweeping statements that make you look like you havent got a clue. This will also discourage other people not to use them who would possibly benefit greatly.
Long Live Microsplitters, Coliods & Detergents they are all great in different ways.
