ᐅ Water dripped from a zinc vase onto the hardwood floor.

Hello everyone,

While we were on vacation, we asked our neighbors to water the plants outside. Unfortunately, they were a bit too thorough and also watered the indoor plants. Apparently, water dripped from the pot onto the hardwood floor for over two weeks. The result can be seen in the picture.
Is there any way to salvage this?
It probably won’t be possible to completely remove the damage, but surely at least the worst of it can be fixed?

Unfortunately, no chance... Just put a runner on it.

I agree,
put something larger on it,
a pot, side table, plant stand, etc.

I would consider having the area replaced. Do you still have any leftover parquet flooring? Otherwise, I think with the right chemicals and a careful touch, you can improve it. Maybe ask a wood specialist (carpenter, joiner) and test their suggested option on a small spot?

Woka offers a product to treat oxidation stains. It works quite well, but it does not remove the stains completely without leaving any trace.

Do the neighbors have personal liability insurance? That would be a typical case. Then it would be professionally replaced – probably the only way. In my opinion, any makeshift repair won’t work.
