The technician was very professional and arrived on time. He explained everything he was going to do and took photos before and after. The only reason I didn't give 5 stars is more my fault than his. He advised not to touch for 24 hrs which was not a problem. But we were away for 5 days and there was a residue on the surface that I should have asked how to remove. I tried gently using DFS cleaner and cream provided. I also tried warm soapy water but it is still sticky. I rang guardsman and was advised I could repeat a little more vigorously & if not resolved, I should send in another report with photos. (Of course, stickiness wont show). I have repeated with some effect but not same feel as rest of sofa. I will repeat again. But I should have asked him before he left.
