I use washing up liquid first (not on the dock) then touch of silver shampoo (there's a stronger weekly one) all over. Leave it on for a good 10 mins. Rinse well then I use net curtain whitener on the bottom only, it's dirt cheap so don't skimp, leave for a couple of mins then rinse well and use a conditioner. It will dry whiter than it looks wet.
