Polishing stone sink

[gotoPzero]

We have a sink that looks a bit like this in our downstairs toilet



Over the last year or so the inside has slowly gone cloudy - I assume from cleaning.

Google suggests it needs a special product to clean and then wax.

Anyone got any suggestions of stuff that works?

I'd be tempted to reach for automotive cutting compound, etc., and see how that goes.

Now that's one thing I definitely wouldn't do as it could all just end up embedded in the grain. AFAIK most stone polishing doesn't use a compound just a fine abraisive tool plus water?

If you're looking to polish the stone then do what the factory did and wet polish it with a flexible pad like you'll find here https://www.atsdiamondtools.co.uk/product-category... likely just needs a burnishing pad as its already polished and hopefully not etched.

If it's a wax coating that needs stripping and reapplying after going milky, or a buildup on the surface, it probably needs doing chemically or just something like a white non-woven finishing pad (white ones are usually the gentle ones).

Hold fire on anything abrasive - i'll ask Wifey (she's cooking tea at the moment) She's been in the 'trade' for over 30 years at one period running the Fabrication dept for one of the largest stone suppliers in the country. I'll post later.....

PS. She says that's a "lava stone pebble basin."

If limescale remover has been used on it the surface may be etched (because acid dissolves stone) - in which case yes it would need something 'cutting' to polish it and then a sealant. Ask a tile shop.

I forgot to remind Wifey and she's gone to bed (probably cos the football's on ) but a couple of photos including a close up of the surface finish would be helpful.
