IW 505 Cleaning ??

[Fairytale]

Hi folks; can anyone suggest the best way of cleaning the white roof on an IW505. Mine has gone quite green which is easy enough to clean but also has dark streaky stains all over it.

Any ideas welcome

Warm water, washing up liquid and one of those shower puff things. It brought my white Bateson up like new - just the right level of abrasiveness without being scratchy.

Scrubbing brush and car wash liquid, rinse with a hose

Warm water, fairy liquid and a washing-up sponge (the sort with one side sponge, one side scratchy). Rubber gloves so your fingers don't go wrinkly. Stepladder. Easypeasy.

I use caravan cleaner and a scrubbing brush
