Thanks Derek ! You almost ruined my day ! No, seriously I do know there are some viscose piles around but I certainly see far fewer than I used to a few years ago. And believe me, I check them very carefully to verify.
Nigel, you are obviously braver than me these days, with your velvet chairs. I too have wet cleaned similar in the past, but these days the very thought gives my ageing ticker palpitations.
