i have a Lazee Boy chair that needs a good clean. It is covered in cream coloured fabric with large non- removable cusions. it needs a thorough clean because of years of body sweat and dust have discoloured it. Just rubbing over with cleaning foam doesn't work very well. Steaming might work. Anyone any reommendations for a procedure or product or professional cleaning service available in Bangkok?

Why clean it now if you haven't bothered to clean it 'over the years'? Buy a new one and take care of it.
