Thank you Judy and I realise, in my last twenty years of cleaning leather, I've been working as an amateur, however, I have a Leather Works on by doorstep ( Bridge of Weir ) and visited them before commencing with leather cleaning.
What was emphasised, at the time, was the fact that you are actually dealing with a synthetic surface, when cleaning, rather than the actual hide.
What I mentioned, was the fact and it's indisputable, that you are more likely to damage a leather suite, by using wrong products, being too aggressive, using brushes , or even cloths, which are too stiff, or course.
Hope to see you up here soon
