Corrector Plate needs cleaning

have to say this is the first time I've heard them been used for this, the general rule before was not use tissues cos of abbrasives lint and the likes, so I suppose this stuff is as pure as it gets.
cotton can be a real mess but its grand really so long as you dont catch any of it on an edge or sharp surface that pulls it apart.
