Polishing old wooden furniture

In my other country I think I once bought
some polish for wooden furniture, but I am
trying to remember if I used it and on what
piece of furniture.

Here I find myself surrounded by old
wooden furniture, so my new life has routines
for polishing furniture!

In particular I feel responsibility to keep my
grandparents' dining table in good shape.

One of the locals suggested using JO-NI
for that job, and I am quite happy with the results.
