Similar one in our local Asda. The top products such as Autoglym and Meguiars quick detailer is safe to lift dust but as for this product claiming to lift dirt without damage, I don't think so somehow. I wouldn't use them.
Load of crap, I would never touch a car with out a pre soak of even just water first, no matter what they say it will damage paint, don't see how it's so Eco as you use about 6 cloths a car, and how can they make a decent profit from the cost of the wash and how long it takes to do the wash
