I've just washed and dried the matt on mine, it' still in great condition except where the first owner dinged it and where I slightly scratched it. But the bike hasn't had daily use and lives in a garage.
Something kind on my skin mostly.What did you use for soap Lou?
I don't know if it's the same there, but our appliance repair people have a safe sticker removal fluid for painted and stainless appliances.I hate that sticker but it's still on there because I don't know how to get it off without ruining the paint
