Does anyone have any good tools to clean the GHD Glide brush? With the inner metal layer of 'bristles', it makes the gaps too narrow and curved for me to get anything like a comb in there, and other tools don't seem to fit either. I am getting a layer of hair and product build up that is smoking a bit as it heats up, and I'd quite like to clean it out, but other than the very outside row of bristles, I can't get anything to fit effectively.
