I have velux rooflights that are about 15 years old now. Some of them especially those in higher moisture areas are getting rather unsughtly in the bottom corners due to the wood turning black. Are these wooden parts easy to replace? Anyone tried it?

Thanks

I have the same, the black is mildew, needs to be cleaned up sanded down and re varnished.
Mildew same as you get anywhere, standard damp type. I use bleach in the bathroom, to get rid of mildew, So wipe with a bleach solution would get rid of the black, then sand it down. re varnish.
