Actually there is no way to know what to do until you find out what's on the lens. When you know call us back. Remember to that when you start trying to clean it there's no sending it back.

I'd give the lens a little ride to Canon and see what type of service they can do, possibly replace the front element. You just might get a nice surprise. Roger(RCicala) and/or one of his tech's might have a decent idea what the element replacement might cost. Not bad results considering the appearance of damage though !!!

Reno is correct. On some lenses the front element is really nothing more than a clear piece of glass for protection and not too expensive to have replaced. Worth letting Canon check it out.. Keep us advised.

Anybody know if this lens is eligible for CPS Repair? It let me register it and gave me 8 points for it so I am assuming it is. However all the links to eligible products seem to be broken.

Yes, Windex works well on lenses.
Acetone is great on glass, but the tricky thing is it can easily effect plastic or paint.
So you have to be very careful with it.
It's not really worth it, unless you are cleaning just loose elements, or you have a problem like glue on an element or whatever.

Update:
It appears the front name plate ring is warped and won't sit flat. Following directions found on another site was I able to remove the front element. The front element is the only one with bubbles but they don't appear in the photos. With enough light the photos are sharp with good color/contrast. I ordered a front name plate for $30 shipped off ebay, $18+6 shipping from Canon parts but they did not have them in stock. The front element itself is $162.74 from Canon parts but I will keep what I have as it seems to work fine just looks bad. So definitely too close to a strong heat source which caused the bubbles in the front element and warped the front plastic ring. After removing the front element and blowing it out I was able to remove the dust specs so all said I have a fully functioning 10-22 for $330. I'm calling this a win!

Modern lens coatings are very hard and don't scratch that easily.
Only true of the exposed coatings, they have a hard top coat.
And don't attempt to clean the new SWC Nano coat(is only on the surfaces that require it).
However, considering how wide your lens is, I'd test it stopped down all the way on a sunny day and make sure the extreme depth of field doesn't start to include the bubbles in any way.

Great article thanks for that link. I did take a few shots stopped down to 5.6 today and noticed nothing in LR. I plan to get lots of use out of this lens so I'm sure something may show up someday.
