main cabin hatch color degrading

[mowa]

I noticed that the main cabin hatch (B39CR 2005) is passing from white to a rust color. Someone has found a product to return it to the original white?

You can get a cleaning product from builders merchants for cleaning plastic window frames. The one I use in the UK is called PVCu Solvent Cleaner made by EverBuild and it does quite a good job, just be careful to wear rubber gloves. Or there's some stuff called "Silky" Available from caravan spares shops which is kinder on hands and also does a good job.
