About eight years ago, I was introduced to a product which, not only killed off dust mites, but gave ongoing protection by destroying eggs which came along later.
The product had amazing protection properties for virtually any surface and was being introduced to a group of carpet cleaners, who were all associated, at that time, with Franklin's of Sheffield.
I believe the product became the subject of a licencing debacle, taking it out of reach of the average c/c and when I last spoke to the UK licencees, they were only interested in selling territories, for substantial fees.
The name of the product was/is Aegis and if was generally available, would, I feel it would have a major impact on the protection and air quality industry.
Surely someone else, on the forum must have been at that meeting..........
