Answer 2

There are two minerals that the term jade is used to describe, nephrite and jadeite. Both of these stones have a slightly porous structure which can absorb staining minerals from ground it has been buried in over the years. It is not possible to remove all these stains and indeed to even try would be a very bad idea. The jade minerals are both safe in water and being tough can be scrubbed with a soft brush to remove loose dirt. Over hundreds of years hard coatings of mineral deposits can form on the surface of jade objects. These can be very stubborn and hard to remove and I recommend that you do not attempt the job yourself as to damage a 2000 year old artifact would be a terrible shame. Take it to a reputable museum and let them do the conservation work.

First we call in the moving company, remove the house hold goods, take it to a safe place, out of which we select the urn, the 2000 year old urn!! we put it to auction, cleaning may damage its originality, and the owner would be putting ads of rewards, by the way, where is it? I want to clean up the whole house for free JUST for that urn! thanks.

Answer 4

Check with an antique dealer before you try to clean that. Antique are usually more valuable if left dirty since cleaning can scratch or wear away things that make it valuable. I've heard many times of people cleaning or repairing something for them to be told it would have been worth $10,000 more if they had left it as it was. Good Luck.

Answer 5

I wouldn't bother cos chances are it will de value the piece but if its covered in mud or something similar water and a soft cloth and a gentle hand

Answer 6

Maybe visit a good antiquing website, just to be sure you *should* clean it... sometimes cleaning an antique can devalue it...
