If you hate throwing away rotten fruits and veggies or food that has expired, let technology help you cut the waste. The free app FoodKeeper lets you take note of what you have in stock in your kitchen and pushes notifications when that item’s “freshness window” is about to come up. Since some foods have a longer shelf life than others, it can be hard to keep track. But with this helpful app (created by the United States Department of Agriculture), you can cut that waste. There are also tips on food storage and what needs to be refrigerated and what can be left on the countertop.

Many of us are converting our garages into workspaces and adding things like air conditioners and heaters to make it habitable for year-round use. To make your garage as energy-efficient as possible, make sure the door is as insulated as possible. Avoid garage doors with windows; they are rarely well-insulated and can leak air very easily. Try to use “triple-layer” doors, which have foam insulation that protects from the elements. And if you use a garage-door opener, opt for one that is designed for low-energy standby mode; it won’t draw as much energy when it's not in use.

Many of us look for safer alternatives to bleach, especially when it comes to disinfecting countertops and surfaces in places like the bathroom. And while white vinegar has been hailed as a biodegradable and disinfecting ingredient here at Do Just One Thing, it’s not strong enough to kill tough bacterial strains like staphylococcus. If you want to truly disinfect, use a vinegar/water solution as a general cleaner and spray hydrogen peroxide after the first clean. This is an antimicrobial approach that can be just as effective as bleach.
