discoloured sealant - cleaning or removal?

[The Night Tripper]

Hi all MIL has some uPVC french windows in a room she's getting redecorated. The white sealant between the windows and the walls/ceiling has become discoloured (it's a room used by smokers) and now the room's being repainted she's unhappy with the way this stands out.

I'm about to advise here it'll need removing/stripping and re-sealing (probably by yours truly ;-/ ) but I thought I'd check here beforehand - is there any mileage in trying to clean it?

Thanks Jon N

Why not find out for yourself and just try cleaning it?
