I have a 03 Cobra with parchment Alcantra inserts. Car is 6 years old and seats look like knew. Use a 8 to 1 mix of Woolite/water in a spary bottle spray seat insert lightly,use a damp cotten towel and rub lightly. After you have cleaned the area go back over the seat with another damp cotton towel. When dry brush the seat and vac.
