That genius was me. Thanks! 
I just cut a paper towel into approximately 3" x 3" pieces and spray 2 to 3 light sprays of Windex on it and wipe it across the plate while leaving a good film of it on there. I use that method every time on my Prusa MK4 that has a smooth plate and it works wonderfully.
I also used to use a mixture of regular white sugar dissolved into hot water and do the same on my Creality CR10-S glass mirror plate to get it prints to stick. That worked great too and once the bed cooled off the print came off easy.
