Thanks guys for all the suggestions.
A solvent would usually delaminate the flock of the buffalo but we'll try the 'on a cotton bud AND hairdryer trick, that's a great idea Kevin, thanks. I'll pop in and have a look myself and explain to the client the option. We have a good solvent spotter but had not thought about the hairdryer trick. I'll let her decide, or as you say Kev, I might be picking the monkey up if it 'goes wrong.
