Those are Hunter Douglas Silhouette blinds. Somfy makes the motor. (Actually they make pretty much all the drives for all motorized blinds).

I had the same problem including bad stains. I ended up replacing my blinds with MCD blinds. I had factory do installation in Fairview, TX. (just north of dallas).

MCD put in dual roller blinds. (Daylight which is kinda like a dark mesh, and night shades which are truly opaque). I could not be happier, especially with the night shades. I can make the entire coach almost light proof and that keeps my dog from waking up with the sunrise. (win-win).

Thanks for the technique on the cleaning!....but if you get tired of having to maintain the blinds, you guys might want to consider MCD.

Cheers,
