My 2005 Super V8 has a few water stains on the headliner around the sunroof. Unfortunately, the drains clogged causing the water to back up. The stains are not bad but I want to remove them, it's my first Jaguar!

I bought 303 TM Fabric & Vinyl Cleaner but am nervous to try. I do not want a sagging headliner. Already had that in my BMW.
