I don't have any APC just now, so I use the power maxed TFR which I really rate, and working in with the detailing brush is very satisfying... I'm easily pleased. Rarely take the powerwasher out, mains pressure on hose works fine.
Once rinsed off I use Aerospace 303 on all plastics.

but I might look out for that meguiars crème stuff in future if I can't get the 303.
