Tap Cartridges - Impossible situation

[Ric2013]

If you have the cartridge, surely job is almost done, or at least worth trying at this point? To be honest, they probably aren't that dirty where the rubber seals were, assuming the rubber seals (O rings) came out in one piece. I'd be inclined to check for dirt and if it looks kind of alright, just push the new cartridges in with some silicone grease.

I sense an unexplained change of plan?

Vinegar works quite well as a descaler, but I'm with Yorkshire on this to some degree in that, if the brass is poor quality, then you may do more harm than good.

Just a bit of silicon grease to ease install of new cartridge, any scouring of surface will be worse...

Looking at the images submitted, I'd say the scale build up def needs cleaning out. The chances of new seals coping with that level of deformation and sealing are slim. Carefully descaling then polishing with 00 wire wool and flushing it all out afterwards will get you the best chance of success.

You're are a glutton for punishment I'll give you that. God only knows why you're doing it. I hope to goodness this old thing is worth all this heartache? Is it solid gold and you've not told us?
