I use a steam cleaner!
I have an upholstery attachment for my steam cleaner.
Hi DeAnn. My name is Cindy. I use a product made by Woolite. It's called "Woolite Rug and Upholstery Cleaner". It comes with a brush built in the lid. Just push the button and a foam comes out. A little goes a long way. Use the built-in brush to scrub the furniture. I have been very happy with results.
