Hi Richard.
Great piece of kit but a bugger to clean, have a 12" slicer similar to yours. I dont drag mine out unless I have something that derserves the cleaning time that follows.
No tricks in my cleaning shedule except to clean ASAP after use and keep Unit covered.
I do remove sliding feeder and clean seperately.
Steaming hot water with sponge & dishwashing liquid, remove all remonents of product that you can see.
Rise many times, then I spray all moving parts with a "No Rinse" sanitisation solution and keep slicer covered.
I respray just before I use again. Good Luck.
