Because of the latest legislation on UN numbers and chemicals, carrier companies are now not letting me send this product in anything over a 5 litre container but I can send as many as I like in 5 litre containers as long as the UN number is on the box!!! Madness rules as ever in Europe!!! So I have made a special price if you order 4 x 5 Litres to compensate. This product G850 is as a universal cleaner,as used by professional valeters and the car and commercial trade in general. It is suitable for use on a wide range of surfaces, including paintwork, fabrics and floors. Contains high foaming, alkaline cleaning agents to remove waxes, oil, grease, traffic film and stubborn stains. It is non-waxing and does not contain any silicone. Will clean exteriors, interiors and even the kitchen sink. Can be diluted if required, strong and economical!
