I have also had the worst luck with our microfiber couch. The thing that I finally found that seems to be the best and easiest is to get some baking soda like you put in the fridge and it has instructions on the box to make a cleaner. I just mixed the soda and water in a spray bottle and it works great. I take the cusions outside and spray them down, if there are bad stains I will use a scrub brush then let them dry in the sun and they are back to new. They are a little stiff at first but after a day or so of being back on the couch they are fine. Good Luck!
