I used DFC 210 as a pre spray and then let it dwell for 15 min. I then got out the pipes and turbo drier and started cleaning under the settee as it wasn't that soiled but gave it a good rinse then 15 mins was up and attacked it big style, had the tubo going when I had done half, then went over with loads of dry passes, had cup of tea and rinsed it all over again, put stuff away and let it dry for a bit before presenting bill.
