Cleaning the sofa

I would first try the recommended products and wait for the result. If it goes wrong, you can still have a new [Bezug] made. There are also special products for that.

I bought upholstery cleaner for my couch when it started to look shabby, but although I chose a high-quality product, I felt that there was no visible change. Meanwhile, I clean my sofa with our pressure washer. Works wonderfully.

Just try a small area of the seat first to be safe and see the result; in my experience, carpet foam works great.
