I found a stiff version of the addis. Its very stiff, but the bristles are quite sparse. Feels like it will be good, but will it scratch the frames? Has anyone tried.

Its lots stiffer than the bentley, but looks just like one.....

Its the yard brush. I use it to clean the soft brush of paint flecks and dirt. I found it far too stiff for cleaning, bit like a rake leaving too many gaps.

Oh. I just used it on my windows (painted frames) you can actually hear it scrubbing. Maybe you're right. But it should be great for first cleans.

What would be ideal is something in between....

It was 2.49 from dunelm mill. So you can buy some curtains at the same time
