You could buy a lemon-scented all-purpose cleaner at the store, or you could make your own using real lemons and some white distilled vinegar. You see, thanks to its concentration of acetic acid, vinegar is a potent cleaner and it’s wildly useful around the kitchen for all sorts of tasks (think: windows, countertops, cabinet hardware, and more).
The only problem is that it, uh, smells like vinegar. That’s where the lemon rinds come in. The oils in the rinds help mask the harsh vinegar smell and they provide a bit of extra cleaning power. Hurray!
