I have just used Turtlewax nanotech wash and wax and I have to say its a great product.  Washes well and gives a really good deep shine.  The nanotech wax is spray on and wipe off.  There's no powder residue and it buffs up with none of the effort that some other waxes need.

I got mine from Halfords.

because its ph neutral 5.5 and it works a absolute treat plus you and your car smell good lol!!!
