I've tried many shampoos for cars in my forty years of motoring, none of them quite did the job - then I discovered this little beauty, the 3M Shampoo Concentrated Liquid, it makes 100 litres from a single bottle, that's what I call concentrated, (why can't they do that with wine or beer?). But the best thing about it is the soft silky feel it gives to your car, never before have I seen a Renault Megane flick its sultry locks so seductively, or sweep back a kiss curl from its pouting bonnet, never have I seen such chrome ringlets and gorgeous pigtails. Beware though, and avoid using this product in the shower. I did once when I'd run out of Head and Shoulders, everything was fine until I realised I'd spent the last three nights sleeping in the garage, and was inadvertently putting Castrol GTX on my cornflakes. Last time I'll do that. Can't recommend this car shampoo enough though, really good stuff. Beep beep.
