How to properly clean the interior of an Audi 80?

I want to keep the interior of my Audi 80 in top condition, but I'm not sure how to properly clean it without damaging the materials. Can someone give me some tips on the best way to clean the interior?

First, always start by vacuuming the interior to remove any loose dirt and debris. Then, use a gentle all-purpose cleaner and a microfiber cloth to wipe down all hard surfaces. Be sure to test the cleaner on a small, hidden area first to make sure it won't damage the material. For tougher spots, you can use a specialized cleaner or even a mixture of water and vinegar.
