What Lubricant does the DJM-s9

I understand you guys don't want people opening up their devices and making things worse, but my mixer is out of warranty and I need to replace the lubricant on the faders.

I had a bunch of dust inside my mixer so I had to clean up all the lubricant, and I would really really appreciate it if you could let me know what I can replace it with so I don't damage my equipment. You keep avoiding the question, which I understand but I can't find any answers and I need to make sure my mixer is working properly or I will just switch to Rane.

So, what is the blue lubricant that you guys use on the faders? Again, my mixer is out of warranty and I need to replace the lubricant.

Thanks.
