Hi Doc,
I think Howard probably has the right answer, depending on the amount of "crud" you need to remove. In the meantime, you might try something like "Flitz" on a small area, and see if that works? It may be less drastic, and it may not work at all - but I'm not sure how much "crud" you need to remove, either.. <img border="0" title="" alt="[Wink]" src="wink.gif" />
