Richie,
Colloidal cleaners have been around for years and I had considered importing then when reading about huge dilution rates, but what I found out about colloidals, is that they were developed for the Laundrette type industry as a prewash emulsifier , rather than a cleaner, by describing them in language that suggests they are NEW TECHNOLOGY is IMO misleading to say the least.
As an emulsifier, they will assist with the cleaning process, but, are they better than, or as good as, traditional presprays.
What the * ***** product is not, is new technology.
