I have a tap that won't turn on properly, and I'm going to attempt cleaning the mechanism as per the tutorial video at https://www.youtube.com/watch?v=o8D-NhReAXY. One of the steps in the process involves lubing the mechanism with silicone grease. This tap is likely to be used at least for teeth-cleaning, and possibly also for drinking water. Is there a particular variety of silicone grease that's safe for this purpose, or will any silicone grease do?
(For regulatory and product-availability purposes, I'm in the UK.)
Thanks very much.
