Can someone recommend a decent product to clean the naff get bit on the VRS seats? My youngest has made a bit of a mess! No idea what cleaner to use, as its like a suede material

It's Alcantara.

 

I've used a few things. Baby wipes work for lots of things.

 

Tesco upholstery cleaner did a decent job on it before I traded in. Pretty potent smell off it so do it on a day you can leave the doors open for a while.

Not used it on the alcantara myself; but for recent fabric and interior cleaning on my car i thoroughly recommend Autobrite FAB  fabric cleaner.   

Have you tried Shout spray? It used to work great on my previous vrs white inserts.
