Notes
🧴 Shelf Life
Lasts 6–12 months if stored in a tightly sealed container, away from heat and light.
Alcohol evaporates quickly, so always keep the lid tightly closed.
Using a dark-colored bottle can help extend shelf life—especially if you're adding essential oils.
🧪 Disinfecting Power
Stays effective as long as the alcohol concentration remains above 60–70%.
Alcohol kills bacteria and viruses within 30–60 seconds of contact when freshly applied.
💡 Tip: If it still smells strongly of alcohol, it’s likely still effective. A weak scent may mean the alcohol has evaporated.
🧂 Formula Notes
No vinegar needed! Unlike my DIY Citrus All-Purpose Cleaner, this mix is vinegar-free, making it safe for most surfaces—including granite and other natural stone.
Essential oils are optional. Always research their safety around pets before using, as some can be toxic (especially to cats and dogs).
