Bongo Fury

help!!! does anyone know how to replace the electric blinds inside the bongo. one of them is quite dirty and im just wondering what kind of job it would be to replace them all?
ps, im new, so apologies in advance.........i have many questions

Pop replacement blinds in the search function. There was a post a few days ago which may be of help

thanks, had a look but ended up havoing a go at cleaning them using simonz upholstery cleaner. has worked wonders but they still have a few marks so will tackle them again at the weekend
