Boat canopy cleaning

[Simpo Two]

At the end of the month my boat has Spring Cleaning Day - and part of this will be to make the hood look as new as possible. It's navy canvas and in the five years from new has gone stiff and a bit green round the edges.

Last year I blasted it in situ with a pressure washer and that made a decent difference but I think it needs more. I aim to take the hood sections off completely and blast them - but should I scrub with algicide/patio cleaner too? I'd like to finish with a restorer/water repellent like the Renovo I used on my TVR.

Can anyone suggest suitable products please? Or will car products do it?

Commercial Vehicle Traffic Film Remover (TFR) is pretty good ,it cleans the tilts on trailers pretty well .
Soak ,scrub and wash ,rinse is what I have done in the past then used hood sealer preserver .
