Ross, nothing you can do do will make her uncranky now, but as usual, I do have a suggestion. Large quantities of alcohol for both problems. LOL
Seriously, you might try a little denatured alcohol on the vinyl. Just check a small area to see what it does, in case it's going to be a big mess. I sure would like to hear other suggestions also.
I had the same cranky wife syndrome for the first time 33 years ago, and the exact anniversary/birthday day will be 6/16. The bad news is that this leads to cranky baby syndrome and finally darned near impossible teenager syndrome. Soon after that, you start to get a lot smarter and the problems get easier--for a while until the cycle repeats.
