Sepends on if you need to it be natural or not. I find that vinegar works really well. Otherwise, if you should go with something like: https://www.amazon.com/BISSELL%C2%AE-Woolite%C2%AE-Advantage-Upholstery-3325/dp/B09WPSCLGT/ref=sr_1_5?crid=1IJRH7WCFHJYC&keywords=upholstery+cleaner&qid=1684955129&sprefix=apphols%2Caps%2C180&sr=8-5

Or you can get a mini carpet/upholstery cleaner on Amazon, but then you're getting more expensive.
