When its wet it is invisible.
You cannot feel any damage.
It literally is just damage to the varnish, so I know its repairable!
If you have a step by step to fix it, please let me know!
Bought some baby oil yesterday as I read it can mask the damage for a short period, i.e. just before moving out! However I would rather something more permanent!
Here is a photo with the baby oil:
