To save yourself a lot of scraping and to get the most oil off your glass:
When you've finished scraping your oil up and there is still a bunch that you can't pick up, just pour a little bit of moonshine or rubbing alcohol onto the glass. Then just swish it all around or scrape at the oil again underneath the moonshine or rubbing alcohol. The alcohol acts to clean it off of the glass and condense it. (I'd say use only 1/4th of a cup for a huge dish). You can then pour this condensed oil into a much smaller plate or tilt the dish so that it's in a corner. and let it dry out again (less alcohol you use, the faster it dries). There you go, much cleaner dish and even more oil that's easy to scrape up.
or
So that you barely have to scrape at all, do the same thing. In the end you have a lot less of an area to scrape because the oil is covering a much smaller area. This helps you collect more oil off the dish and saves you a lot of needless scraping.
You can also save yourself some drying time by putting the oil into an even bigger glass dish to dry it off fast at first and then collect it with the alcohol. It doesn't make a difference how big the first dish is because you aren't going to have to scrape it anyway.
