[A/S] Drape stains...Water?

["savh_steve" <savh_steve@xxxxxxxxx>]

The window drapes on my recently purchased Excello are stained on the 
liner that is close to the windows. Looks to me that the brown stains 
(seen from the outside) may be from condensation while sitting up. I 
was thinking of soaking in OxiClean overnight, but thought some of 
you may have a better suggestion. 

Are there any "don'ts" in cleaning the drapes that I should avoid? 

Thanks for your expertese!!
