What container is the water in? If it is a mixing cup or glass cup, there will likely be residual fats that linger after washing. There are also various grease,s fats, and other lipids in you water pipes, faucets, and the kitchen air since particles linger around. Everything in a kitchen will start to develop a small film of grease if it isn’t cleaned constantly. It’s not harmful and you have been consuming it for literally your entire life
Looks like a glass jar to contain water. Previous tenants could have used them to store literally anything so yeah, residual fats doesn’t sound that surprising now that I think about it.
Maybe I should be paying more attention to the stuff around me instead of only while I’m overseas 🙃
