We have three nested tables that are stained reddish brown.

The problem is that, since the tables were handed down to
us, water condensations from the cold soda cup leaves a pool
of water, washing away the paint.

I love the way you phrase this. I know a bit about wood, and I can
assure you that water condesations damaged the wood in the same way
before the tables were handed down to you. The difference is not
time, but that your grandmother didn't let such things happen.

Don't blame the year or the cold soda cup or the water.

This is seen by the white
circular marks on the table.What is a practical solution to
solve and prevent this problem?

Thanks
