I bought this to clean 2 inch faux wood blinds. Performance is so-so. While the brush works well between the blinds, I expected the brush to clean more effectively. Perhaps this is because the blinds have not been cleaned for a long time and too much dust has accumulated. I do not know. I ended up removing all the fins, wiping them down and putting them back in place. That was also a lot of work, but the result was cleaner. This is an interesting design and an expensive brush. than artificial blinds.Your mileage may vary. :)
