My glass beds are too clean for PLA?

Problem solved! Putting 20 dessicant bags inside a 20 gallon ziploc bag solved the issue. One of my printers wasn't sticking to the glass bed, no matter how clean it was, so I put in the bag for two days and reloaded it on the same machine, and now it's printing like a charm. So, for the record, both ABS and PLA like to be dry or otherwise they won't stick to glass beds.
