Why are the stones in the antique market so bright? What kind of oil is it? Is this oil suitable for stone maintenance in hotel lobby?

Maintenance oil is also very particular.

I usually use four seasons spring white oil for Shoushan stone, but now I use liquid paraffin.

Rapeseed oil is used in Chang fossil, which is very strange.

And some wooden furniture. I have seen people in Shandong dip peanut oil in it to make shells and patina.

To sum up, many things are based on local materials and experience.
