Well, a good start would be to buy
this kit before they run out/put it back up to £50, it's stupidly cheap and consists of the main staples I use to clean mine.
A good wash mitt and a couple of premium drying towels are also essential.
This website will make you spend a lot of money!
Would also be wise checking out a few progress threads, particularly
@sevenfourate and
@Dystant who like a good clean, but everyone's at it:
