Cabin headlining stains

[MercinaryPilot]

I have quite bad staining on the headlining of my 2400SCR 1996 over this winter, any ideas where it might be coming from folks?

Could be mold. If my cuddy shows mold I use bleach thinned with water.

The railing posts are attached with bolts straight through.

His stains are higher up. The bow rail attaches to the flat area when to top deck meets the side of the hull. I’m uncertain where that water is getting in, maybe at the hatch. I wonder if someone drilled into the deck to add something and didn’t seal the holes.

my stains were caused by a couple of things (windshield wiper and rubrail screws have been bad), but the worst was a couple of Drink Holder screws! (1994 3200scr). Bleach watered down got rid of them.

All good suggestions but the 2400 has no OEM drink holders up front and only a starboard side wiper.

If the OP could provide some pictures of his boats bow that may help. Yes diluted bleach, oxy cleaner or there is another product for cleaning awnings that folks say works well. I don’t recall its name but you may be able to find it using the search tool.

Found it, IOSSO cleaner. A Google search will give you sellers.

No other additions to the deck area, so it is a bit of a mystery. Especially as the other side is clear. I’ve resealed the rail posts on that side too, so should be all good there.

it looks like a railing post is leaking to me.

[MercinaryPilot]

Railing posts are at the lowest point of the staining, so I doubt the water would be travelling upwards towards the highest point. I’ll try mould cleaner, see if it clears it.

can't be the hatch either?

[MercinaryPilot]

I don’t think it’s the hatch. No water tracks from it, although the stupid design of having the handles on the perspex is a bad idea, as recently the perspex decided to open but without the frame it sits in! I’m guessing the rubber seal is needing replaced although the hatch is only 3 years old as the previous owner had it changed.

No condensation inside the boat on any surface so definitely a mystery.

Has anyone tried removing parts the headlining with a view to re glueing back up?
