I just wanted to warn everyone who has leather seats in their beloved machines - DON'T use cheap car valeting services.
In fact, don't use ANY valeting that you are unsure about. Do it yourself, properly - or face the consequences.
I had my car pressure washed, waxed & valeted for 25 quid. I asked them beforehand "Do you use proper leather cleaners, etc.?" - "Yes, yes, of course, we only use good car cosmetics".
But when they finished... My god, it was a disaster. They cleaned it alright on the outside, but the interior...
Firstly, it REEKED of some foul artificial fragrance that was meant to be citrus, but it actually smelled like a revolting chemistry lesson I had to drive with my windows open for a week after that, otherwise I would have either heaved or choked.
Secondly, they totally RUINED my leather. I think they used the same stuff on the dash as on the seats, because they became very shiney, hard to touch, and made this leathery rubbing noise (not sure how to describe it) every time I moved. The foul stuff also made them slippery - not a funny thing when you're as skinny as I am and the seats are a bit too big!
It took me hours of work to clean it off to the point where I could at least get into the car without wanting to get out of it straight away. I actually took me a few weeks and two more thorough cleans to restore its previous luxurious matt softness.
Also, the stuff they used on the dash... I hated it, with a passion. It gave it the cheapest glossy looks imaginable. And made it slippery. And made my steering wheel slippery - which I hated even more, because it's a leather Mtec2, wonderful to drive with - but only if you can get a proper hold of it!
Bottom line: if you want it done properly, do it your own self!
