When I spoke to John Woltjen, the inventor of ROR, he specifically said not to use lens tissue because it is not absorbent enough. He said to use either Kimwipes EX-L or Kleenex. It is also important to use it sparingly. I would think that another cleaning would remove the problem. I hope this helps. Richard Wasserman
