Stick to BMW products or as also recommended Ragtop, that's a 2 part cleaner and protector and don't risk a £££'s roof.
I think I will get some of this "Raggtop" stuff. I take it that "Raggtop" is a cleaner? I noticed that my top because it's 5 years old is not one consistent black color. Is there anything to get it back to that brand new solid black color?Ztandem said:Raggtop is recommended by the company that makes the cloth top for the Z4 and many others. I've used the cleaner and it works well. I use 303 protectant after cleaning and the water bubbles for months. I now have to wipe off the top after washing since the water is just sitting there in bubbles.
