How to Clean and Declutter Your Garage in 8 Steps
1. Decide What to Keep and What Can Go
Aside from the daunting idea of cleaning out your garage, it can be difficult to let go of some of the things you’ve kept over the years. When all else fails, channel your inner Marie Kondo and ask yourself, “Does this bring me joy?” Use these tips to declutter your garage and sort everything into one of the following piles: keep, donate, sell, misplaced items and trash.
Ask yourself the following questions when deciding if you should keep something:
- Do I truly need this? Be honest. If you really do use it, leave it in the keep pile. Otherwise, say goodbye.
- Can it be repurposed? If you can reuse the item, it may be worth keeping, but only if you’ll follow through with repurposing it.
- Did I forget this even existed? If you’ve gone this long without it and never missed it, it can go.
- Do I have more than one of this item? If you have multiple, you probably only need one or a few. Can you downsize?
- Is this item worth the space it’s taking up? If you’re keeping old items because you plan on fixing them up but haven't, it’s not worth the space.
- Am I keeping this for sentimental reasons? Are you keeping it just to have it? It might be time to let it go.
- Have I used it at least once in the last year? If the answer is no, it’s probably safe to put this item in one of the other piles.
- If I’m saving this “just in case,” do I see myself using it? If you're worried about tossing an item because you may need it — have you needed it so far?
- Could others benefit from this more than I could, or could I make money by selling it? If the answer is yes, you should get rid of these items.
If you were able to part with it, what should you do with it? On to the things you no longer need.
2. Take Your Donate Pile to a Local Charity
From sports equipment to patio furniture, a variety of items can be donated. Someone else might be able to put it to good use and you can deduct the donation from your taxes. Places like Goodwill, The Salvation Army and other local thrift stores are great places to take your unwanted items. Make sure to check the store’s donation guidelines before dropping your boxes off.
If you’re getting rid of furniture or other large items, consider dropping them off at your nearest Habitat for Humanity ReStore.
3. Sell Items in Good Condition
If you’re getting rid of a specialty item or something with a higher value, you may want to consider selling it. Maybe you can make some money back on what you no longer need. We’ve rounded up a few different ways you can sell your unwanted items.
List it Online
There are several websites and apps that can be used to sell items online. All it takes is a picture and a description. You can try listing on:
- Facebook Marketplace
