I’m renting out part of my home to a couple but they frequently leave what I think is baking soda by my doorstop. Why would they do this?

As a landlord or homeowner, it’s common to have experiences that leave you puzzled. Renting out a part of your home can be a source of extra income, but it may also bring unexpected situations that you might find difficult to navigate without jeopardizing your relationship with your tenants. Such a scenario is finding what you believe is baking soda by your doorstep, left frequently by the couple renting from you.
Naturally, you might be hesitant to address this directly as it could be deemed intrusive or rude, but the curiosity and concern over this peculiar behavior can be hard to shake off. Why would your tenants leave a common kitchen staple like baking soda by your door? This article offers some plausible explanations and guidance on how to approach the situation diplomatically.
Understanding the Possible Reasons Behind the Baking Soda
1. Odor neutralization: Baking soda is a well-known deodorizer that can absorb and neutralize odors. If there’s an unpleasant smell near your home’s entrance, the tenants might be using baking soda to keep the area smelling fresh.
2. Humidity control: Baking soda can also help to control humidity and absorb moisture, which is particularly helpful in damp areas. Your tenants may be trying to prevent mold or mildew, which can proliferate near entryways where shoes are stored or where there is increased exposure to outdoor elements.
