Can you soak them in the bathtub and clean them? What could I use to not ruin them?

In cases where the blind needs additional cleaning beyond dusting you can clean your faux wood blinds by using a soft, lightly damp cloth or sponge and wiping over the slats. The privacy slats can be removed, cleaned and then placed back into position one at a time. Do not use any kind of abrasive cleaner on the product. It is not advisable to soak the product. - Kimberly
