Whilst I remember I recently bought some Autoglym 500ml Interior Shampoo from Amazon with some Christmas vouchers I had to try and clean up the original full width rock n rolls bed that looked like this when I bought the bus and which had what looked like either engine oil / red wine or blood across 2/3 of it in the middle: After: I was genuinely AMAZED it worked and would recommend anyone with similar fabric issues give it a try and it saved me 2 meters of Westy fabric which I was convinced I would need to recover it!
