How can I find a good way to clean a soiled couch?

One option is to use an upholstery cleaner or foam. You can also try using a mixture of baking soda and water, as this will help break down the dirt on your couch. If you don't have any of these products handy, you could also try vacuuming it gently with a brush attachment. Lastly, if possible, try spot cleaning the stain with a mild detergent and warm water.
