Does anyone know how to get these things off without screwing them up. They screw right on but when you try to unscrew them they tighten. I know I can prolly grab the inside edge with a vice-grip and screw it off but that will likely scratch the heck out of brass spring. I want to remove them so I can remove the grill covering the fans on my insert. I would like to vacuum under there and see if there is any way to lubricate the fans.
In the picture I had to put the fireplace glove behind it because I kept getting too much glare.
