Hi Rob,
Those seats look very nice; they remind me a bit of my Recaros from my old Ford Fiesta RST (J reg) that I owned a few years ago.
Can I offer a bit of advice with regards to stain removal? My seats needed a spruce up as they had a couple of watermarks amongst other marks/stains. I'd tried a steam cleaner first, with limited results. I purchased a 500ml bottle of Vanish carpet stain remover, which is for upholstery as well as carpets, from Tesco. For reference, it's the Oxi Action Intelligence Plus bottle. Anyway, I sprayed it on to the upholstery. It came out as a liquid that then turned into foam. I let it sit for a minute or two before working it into the fabric, and then wiped it down. The results were brilliant. I didn't want to clog your thread up with pictures but you can see the results on the first page of my thread. It's an excellent product that causes no unnecessary mess and is kind to the upholstery.
I promise I'm not a Vanish sales rep but thought I would offer you my advice, although I’m sure you already have something in mind.
Thanks Rob,
James.
