I want to clean the inner part of my cabrio roof. How can i do it the best ?

I would try just very mild soap/water on a damp terry cloth. Are you de-dusting or trying to clean some sort of stain?

Lee

every time the roof is folded into the roof cabinet, the inner part gets it touch with 4 contact points.
The left and right flaps and the upper part of the back Headrest(?).(Head protection frame?)
This created after a while a very typical pattern on the inner roof, because you cannot keep this points 100% clean.

Have you tried the household stain-remover "Tech"? You can get it at some department stores and Ace Hardware. It is a non-toxic, non-staining, etc spot cleaner that works pretty well on fabrics. It is made by:

"TECH Enterprises, INC
901 Stewart Street
Madison, WI USA 53713"

After soap and water, I'd give Tech a try. The degreaser Goop may work, but I'd try a test patch first.

Hope this helps...Lee
