Interior trim becoming unstuck

[Ala Larj]

Hi, the cloth trim on my B pillar has become unstuck. Has anyone experienced this and know how to restick it without removing the trim?

Also, it has become a bit grubby. What is the best product to clean it?

Thanks,
Alan

Shouldnt really be coming off. 

Looks like moisture may have gone in and caused it to remove the glue. 

Dont really know what else to suggest than removing it and resticking it back on making sure to check for any leaks etc.

All purpose cleaner or carpet cleaner would work well enough

I suspect it's rain coming through a slightly open window due to the grubby bit. I've always been concerned about removing trim panels as there's no obvious screws these days. Am also wary about airbags as I don't know where they are!
