I know some of you S&Bers have these; can anyone please recommend a dry cleaner for them either in London or West Hertfordshire? I have a Kensington which is looking a bit grubby but my work dry cleaner freaked me out by saying the colour from the leather buckles would run so I'm too scared to let them near it. I don't know if my local Johnsons would be madness - it would be good to know if there's somewhere which has cleaned one and not wrecked it!
