Rationel Front Door - Stained

Hi - Can anybody help with the following please? I have a Rationel Front Door - orange coloured wood....It is about 5 years old and has become stained - like Mildew / Damp stains...Grey/Black in colour - I have tried a few detergents that won't shift the stains....Has anybody any suggestions?

Many Thanks

Thats the timber deteriorating from dampness. The timber is softwood and unfortunately softwood if not suitable to the climate that we have here in Ireland therefore it won't last as long as hardwood.

To prolong it's life make sure to have it resealed with varnish (if you don't mind the look of the damp spot) or stain it a bit darker or have it painted.

Many Thanks for the reply NHG - Think painting is the only route then...cheers
