    You are not alone Jim...

    For my part, I recall watching with horror as my daughter, while sitting on my lap, picked up an element I just re-cemented off my desk (I won't say which lens) and launched it accross the room, spraying shattered glass as it bounced off a tiled floor.

    Who would have thought that a nine-month-old could throw so far?

    Anyone can appreciate a fine print. But it takes a real photographer to appreciate a fine negative.

    Another thing I always keep on hand for removing stubborn crud from lenses is Cerium Oxide. The finest grit available. A tiny amount on a wet cotton ball will really make it sparkle, without danger of harming the lens. Unless you rub for two weeks.

    Send it to a specialist who can clean it up and restrore it. If it's worth it that's what you need to do. We all make mistakes and have things happen to us that are beyond our control. Sure you could have fixed the ceiling but in a real world a lot of us would have done exactly what you did.

    If you don't fix the lens your out a lens and have to buy a replacement and you will always look at the lens and wonder what you could / should have done.

    Is that anything like "Hasn't scratched yet" Bon Ami?

    How about 'Glass Wax' ?
    Maybe Elmer's Glue---let it dry and peel it off?
    WD-40?
    Coca Cola?
    Sprayway Glass Cleaner?
    Efferdent?
    Alka Seltzer?
    A-1 Steak Sauce (let the dog lick it clean?)
    Cascade in the dishwasher?
    Mrs Paul's Sudsy ammonia(diluted of course)
    White wine
    Club soda
    Jalapeno pepper juice from a jar of J-peppers.

    Any combination of the above

    Cerium oxide will also remove older "cold" coatings from lenses so be careful if this lens was coated this way. Using cerium oxide is a good method to remove older deteriorated coatings from lenses. You should not use it with modern coatings.

    I think using acetone should be Jim's first trial method. Make sure you apply it with 100% cotton/cotton rag. Do not use any cloths/rags with polyester, etc., because the acetone will break down the material and deposit it on your lens.

    Maybe if I screw a good sized lens shade on and drink my red wine out of it for the next month? Not that fond of white wine. My daddy brought me up on dago red. Actually I'm considering Curt's suggestion carefully.

    I think Donald is onto something. I would start with distilled H2O but I suspect that won't touch it. I would then go down the list:

    Carbonated water,
    Vinager - white distilled,
    IPA - no, not India Pale Ale,
    acetone.

    Stop there.

    The idea of using rottenstone or any other compound scares the devil out of me. How many microns need come off before you've hosed the lens? Not many from my experiences grinding telescope mirrors.

    Try the coca cola, and no I am not nuts. It contains a very mild concentration of phosphoric acid. I have used it to clean salt water spray off of the glass globe of a nautical compass with out damageing the brass mounting.

    I was given an old camera (worthless) with a lens, they were both so filthy from hard water (I guess someone had them near their kitchen sink or something...) and decided to salvage the screws, springs and what not from the camera body. I took off the lens and experimented with ZAP (which is for shower doors, pretty much the same thing as CLR). I put some on a swab of cotton and rubbed it gently. The dirt and grime went away, I rinsed then with some windex solution and dried with a microfiber cloth. The glass looked like new. BTW, it was uncoated.
