DEAR HELOISE: Trash cans can develop odors even after you empty them, but a quick step keeps smells under control.

Sprinkle a thin layer of baking soda at the bottom of the can before adding a new bag. The baking soda absorbs odors throughout the week.

After noticing lingering smells in my kitchen, I added this to my routine, and it made a noticeable difference right away. For extra freshness, wipe the inside of the can occasionally with a mild cleaner.

DEAR HELOISE: Foggy bathroom mirrors can slow down your morning routine, so here’s a simple trick to keep them clear: Rub a small amount of shaving cream onto the mirror, then wipe it off with a clean cloth, which leaves behind a thin layer that prevents fog from forming.

I was tired of wiping the mirror after every shower. Now it stays clear long enough to get ready without interruptions. I repeat the process every few days.

DEAR HELOISE: Fresh herbs can wilt quickly if they sit in the fridge for too long. I started treating them like flowers, and it made a big difference. I trim the stems slightly and place the herbs in a glass with a little water. Then I cover it loosely with a plastic bag and store it in the refrigerator. The herbs stay hydrated and fresh for days longer.

Change the water every couple of days to keep things clean. Some herbs like basil do better at room temperature, so adjust as needed. It’s a simple way to stretch your grocery budget and keep meals tasting fresh.

DEAR HELOISE: Stubborn jar lids can be frustrating, especially when nothing seems to work, but a quick tap usually does the trick. Gently tap the edge of the lid against the counter to break the seal, then twist it open. You can also run the lid under warm water for a few seconds to help it expand.

I started doing this after struggling with a jar of pasta sauce that refused to budge. Now I don’t waste time wrestling with lids.

A better grip from a rubber band can also help if needed. This simple approach saves effort and avoids the risk of spills.
