Hi Fox, I totally agree about only cleaning computers if you have training - the consequences of things going wrong can be very costly in this area of the cleaning market.
The distributor for this product (and I am trying to find out if they have the UK exclusive rights) is one of, if not the largest, computer cleaning specialists - offering a nationwide service.
However, accepting that some businesses will insist upon their own staff cleaning their IT equipment, they also supply a wide range of specialist cleaning chemicals and materials.
This way they get two bites at the cherry!
In the real world, those companies that do expect their staff to clean their own PC's are kidding themselves. They have no training, and if they did attempt to clean them it would be superficial - and take more time than a specialist could do it in. It is a false economy.
