I use ulpolstery cleaner from the auto parts store. I wear rubber gloves and spray the fabric very wet and work it by hand and then use my wet/dry shop vac to vacuum it dry removing the dirty cleaner as we go. I work about a 2 foot square area then suck it dry and move to the next area. I use my gloved hand because its easy to tease the fabric on my version of rat fur. Make sure to open all your windows
as some of this spray stuff is very fume'ie. If I didnt use the ulpolstery cleaner I would probably use woolite cleaner.
