How to Declutter Your Home (with Trash Bags)

Updated September 2026

Decluttering gets easier when every item has a clear place to go. The trash bag method sorts your belongings into four categories: Keep, Donate, Trash, and Maybe. Each category gets its own bag, matched to the type of items you are sorting.

Use clear bags for clothing storage, heavy-duty black bags for clothing donations, and high-density bags for paper shredding. For general trash, use a 42-gallon contractor bag. Blue or clear bags work for recycling.

The method gives you a practical way to sort a room without mixing items with different destinations. Start with one area, choose the right bag for each category, and work through your belongings one item at a time.

The Four Piles

Keep

For clothing you plan to keep but are not currently using, clear bags are the recommended option for clothing storage. The contents remain visible, which makes it easier to identify stored clothing without opening the bag. This works well for off-season clothes and other garments you want to keep separate from your everyday wardrobe. See the clear bags collection for available options.

Donate

Keep clothing donations separate from clothes you plan to store or discard. Heavy-duty black bags are used for clothing donations in the existing bag recommendations. Sort donated clothing into its own bag as you work through the room. Browse the heavy-duty black bags collection for this type of sorting.

Trash

The type of waste determines which bag makes sense. High-density bags are listed for paper shredding, while 42-gallon contractor bags are listed for general trash. 

Bag material also matters when the waste includes sharp or jagged items. Linear low-density polyethylene (LLDPE) is highly resistant to punctures and tears. It is used for waste such as wood, plaster, glass, and items with nails.

Maybe

The Maybe pile is for items you have not decided to keep, donate, or discard. Keep these items separate while you finish the rest of the room.

A clear bag keeps the contents visible while you make the decision. Do not mix Maybe items with clothing donations, stored clothing, or trash. Once the main sorting is finished, go through this pile and decide where each item belongs.

The four categories keep the sorting process organized: Keep, Donate, Trash, and Maybe. Match the bag to the contents, then check the trash bag size chart to make sure the dimensions fit what you are storing or removing.

Putting It to Work: Closet, Office, Garage

The Closet

According to NAPO, the average person wears 20% of the clothes they own 80% of the time.

"First, clear everything out of the closet," describes Rose Kaye, a professional organizer and owner and founder of Savvy Organizing Solutions, a Cleveland-based company helping people and businesses declutter and get organized. "What is worn frequently can go directly back into the closet."

For the rest of your clothes, Kaye gives a practical rule of thumb: "If you haven't worn something in 6-12 months, throw it away, sell it or donate it."

"If you have children," Kaye continues, "a great way to declutter is to put in storage all the clothes that no longer fit or are not going to be worn until next season."

Use the four piles to separate these decisions. Put frequently worn clothing in Keep. Place unwanted clothing in Donate if it is still suitable for someone else. Use Trash for clothing that should not be kept or donated. Put clothing you are unsure about in Maybe until you make a final decision.

The bag recommendations from the original article give each clothing category a specific use. Clear bags are recommended for clothing storage because the contents remain visible. Heavy-duty black bags are recommended for clothing donations. Keeping these categories separate prevents stored clothing from getting mixed with donations or items headed for disposal.

The Home Office

According to Harris Interactive, 23% of adults pay their bills late because they cannot find them.

Start with the papers that have accumulated on your desk, in file folders, and around your workspace. Sort each item into Keep, Trash, or Maybe. Important documents stay in Keep. Papers that no longer serve a purpose go into Trash. Anything that needs more consideration can stay in Maybe while you finish the rest of the office.

"Throw out as much as possible," Kaye explains. "Categorize what's left over and put the items in labeled file folders or a desktop organizer." Kaye suggests saving tax returns for 5-7 years before throwing them out.

"Making media files of important documents with a scanner, tablet or smartphone is another great way to declutter your home office," explains Kaye. "Just be sure to back everything up."

For paper that belongs in the Trash pile, the original bag recommendations identify high-density bags for paper shredding. This keeps shredded documents separate from other household waste while you work through the office.

Before throwing away financial records, tax documents, or other sensitive paperwork, check the applicable record-retention requirements. Shred documents that contain personal or financial information rather than placing them intact in a trash bag.

The Garage

According to the U.S. Department of Energy, 25% of homeowners cannot fit a car inside their two-car garage.

Start the garage decluttering process by removing everything from the space. Then sort each item based on whether you use it, want to give it away, need to discard it, or have not decided what to do with it.

"Sort what is still used vs. what is never used," Kaye describes. "Then make a pile for give away/garage sale. After sorting, use vinyl covered hooks to hang bikes, sleds, winter tires, folding lawn chairs and ladders. Mounting rakes, brooms, and shovels to the garage walls is a great space-saver."

The garage is where the four-pile method can involve several different types of waste. Match the bag to the material instead of putting everything into one bag:

General trash: The original recommendations specify 42-gallon contractor bags for general trash. The examples include cardboard boxes, picture frames, flower pots, magazines, and old tiles.

• Clothing donations: The original article recommends 31-33 gallon contractor bags for clothing donations. A white paint marker can be used to label the bags.

• Recycling: Blue or clear bags are recommended for recycling. The original article notes that these colors make it easier to separate glass, paper, and plastic.

• Keep: Items that belong in storage should remain separate from trash and donations. For clothing and other stored items, clear bags can make the contents easier to identify.

• Maybe: Keep undecided items separate until you finish sorting the garage. This prevents items that still need a decision from being accidentally donated or discarded. 

The bag size also needs to match the container. A bag that is too small may not provide enough coverage, while an oversized bag can be difficult to manage. Check the trash bag size chart to compare bag dimensions with your container before ordering.

Why Bags, Not Bins

Plastic bins are useful for things you have already decided to keep. For the first pass through a cluttered room, bags give each category a clear place. Use one for donations, one for trash, and a separate one for items you still need to decide about.

That makes the sorting process easier to manage. Label each bag as you work so you know what belongs in it. Once a category is finished, move the bag out of your work area. Keep donation bags together, remove trash from the room, and keep Maybe items separate until you make a final decision.

"People need to find pleasure in throwing things away," reveals Kaye. "Just because you treasure something, doesn't mean you have to keep it. Instead of items cluttering up your home, you can get money for them or give them to someone who can use them."

"The key is not to get overwhelmed," concludes Kaye. "If you focus on one area at a time, you'll quickly see the clutter start to disappear. Afterwards, you'll feel amazing."

FAQ

What size trash bag is best for decluttering a closet?

The right bag size depends on what you are removing or storing. For example, the original guide recommends 31-33 gallon contractor bags for clothing donations. Use the trash bag size chart to compare the bag's dimensions with the clothing you need to store. This is especially useful when sorting a small closet, a full wardrobe, or seasonal clothing.

Should I use clear or black bags when decluttering?

Use clear trash bags for clothing storage. The original guide recommends them because you can see the clothing inside. For clothing donations, it recommends heavy-duty black trash bags. Keep stored clothing and donations in separate bags so each category remains clear during the decluttering process.

How many trash bags do I need for a full room declutter?

There is no fixed number of trash bags for every room. The amount depends on how much you are sorting and which categories apply. A closet may produce clothing for storage and donation. A home office may produce shredded paper. A garage may produce general trash and recyclable materials. Sort the room first, then choose the appropriate bag for each type of material.

Shop the Right Bag for the Job

Choose the bag based on what you are sorting, storing, donating, or throwing away. Use the clear bags collection for Keep and Maybe items when you want to see the contents. Use heavy-duty black bags for clothing donations.
