PTFE Stuck In Lower Idler Bearing???

Hi Everyone,

So, I have never had a filament runout material change work properly on my XL (that is another problem).  I have to open the idler every time to pull out the filament.  This time, when opening the idler, I noticed some white stuff on the lower bearing.  I only print black material, so this was odd.  I started pulling at it and it seemed to resemble that Teflon tape you use for sealing water hoses in your bathroom.  I was able to pull it all out, but am really curious what this could have been.  Please see attached pictures.  Any thoughts?  Thank you!
