Olive oil is acidic and can lead to bronze/copper disease down the road. Especially when it goes rancid and triggers more oxidation. The distilled water only breaks down the mineralization and wont eat away the patina like olive oil does, nor will ti darken it. If a coin is beyond saving with really bad or no patina, and you want to use something acidic just to make out more detail; use absorbic acid solution then neutralize when finished with baking soda water. But it works quickly and can be easily overdone. That way theres no acidity when sealing and the wax wont go rancid or allow oxygen to permeate and continue degrading the coin.
