Yarp, any of the Maguiars stuff is pretty recommended by all on this site. Any of there waxes, polishes, shampoos, detailers etc etc you get the picture. Some say its expensive but personally I dont really think it is. I used the shampoo, gold liquid wax ( I think thats what it is) and the Alloy wheel cleaner and tyre cleaner products.
really are worth it. A slight cheap option is the new Turtlewax Ice range. I also use the Liquid Ice Polish and the Ice Detailer. Both give excellant results.
Halfords did have 3for2 on all cleaner stuff recently unsure if that is still on, but it did include Maguiars stuff. Yep Halfords sell it too.
Happy cleaning
Andy
