To me if it can only be dry cleaned, that's a deal breaker. I read the laundry instructions and it can definitely be put in the washing machine and dryer. In fact when I pulled it out of the dryer, which is when I noticed the stain, the shirt otherwise looked fantastic. It states on the label that if you take it out of the dryer right away and hang it up, it will never need to be ironed.
So all I ended up doing after finding the stain was soaking the shirt in cool water with some Tide Active Lift laundry detergent, which is the type I use in my washing machine anyway, then ran in through the washing machine again since I had to do a load of light coloured towels anyway, and that's it...no scrubbing, no bleach, nothing else. Then I let it air dry. So I don't think I did any damage to it but I'm going to take it to the cleaners anyway tomorrow to see if he can get the wee bit out. If not, I think it's wearable anyway as I had both hubby and DS look and they said they couldn't even see the stain (in fact I think DS thinks I'm nuts).
Thanks for all the suggestions!
