Brighten Up Dull Aluminum
Just because your aluminum products have gotten a bit dull, that doesn’t mean they can’t be revived! Take the open-facing half of a sliced lemon and rub it all over the aluminum. After this, buff out the aluminum product with a soft cloth. Your aluminum will be shining again!
Remove Rust
Since lemons are so acidic, they actually do a great job of removing rust stains from things. This can be really helpful wherever you store iron cans, like shaving cream in the shower. All you need for this remedy is salt and half a lemon. Sprinkle the salt on the stain and scrub it away with the open half of a lemon. Let it sit for a few hours, and even let the lemon sit on the stain overnight, then rinse it off the next day.
