Our bathroom sink has a spring loaded pop up waste - basically you push it down and it clicks into place and then you push it again to release it. ( http://www.ebay.co.uk/itm/180845761546 is similar) It has a rubber/silicon washer that actually does the sealing. This seal is now dragging and making it difficult to unlock and needs lubricating. I've tried ordinary plumbing type silicone grease but it doesn't last more than a week or so. So has anyone got suggestion for a suitable lubricant that can witstand hot water?
