The glass to the bottom shelf is SO difficult to remove. Using the user manual that came with the fridge did NOT provide us with any correct instructions to remove the glass. All of the Samsung help videos include basic clips which are used to hold the glass in place, for what ever reason this RF32CG5100SR HAD to be different.  After SEVERAL google searches later we found a YouTube video NOT from Samsung that showed us how to get it out to clean. YouTube video: https://www.youtube.com/watch?v=pgBq8D9uHKs. This was NOT the safest option and could very likely lead to breaking the glass or the frame. But we did successfully get it out and cleaned. Putting the glass back in the frame was even more of a struggle.
