  • Have you checked the manufacturer's documentation on what the proper product to use is? That would be my starting point.

  • Hello, and welcome to Home Improvement. It's a little hard to understand your post; would you spend a little time fixing capitalization and sentences, and splitting it into a paragraph or two?

    Why do you feel you need to break open that unit and "lubricate between the ceramic-discs that are located inside the plastic cartridge of a single lever mixer faucet." ? I would assume that if the manufacturer wanted you to do that they would have given you the instruction and info to do it. ? Potable or Portable ?

    Silicone grease is silicone grease, if there were a special requirement, the manufacturer's documents and/or website would be the place to look. Some brands even use Teflon lubricants... the only thing that usually matters, is that it be an approved food grade lubricant.
