Cleaning agent for soft top 9510252 for Volvo?

Alot of people don't realize that you can use reqular car wash soap to clean the top. If I were you I would clean the soft top first, use a 5 gallon bucket or whatever you have to hand wash fill it almost completely with water and mix only about a half a cap of soap into the water (the cap that's on the car wash soap bottle), you wont get to much suds but it will still clean. Once your done go ahead and rinse it off the top. Add more soap if you want and clean the rest of the car.
