If you think hard enough, there's a high chance that you can remember exactly what your grandma's house smelled like. We bet it always smelled fresh and clean, but that's not just because she was on top of her home maintenance. Grandmas' houses always smell fresh because they use the old-school hack of making their own linen spray rather than buying it from the store. And this allowed them to personalize it to their own scent requests.
You can do the same if you simply mix rubbing alcohol with water and the essential oil of your choice. If you then pop it in a spray bottle, you can spray it on your linens for extra freshness.
