If you want to declutter your home, buying a few big plastic tubs can be very tempting.

You can toss whatever you don't need regularly, but don't want to get rid of, into the bins, stack them somewhere out of view and have a more organised home.

It can also free up a lot of much-needed space.

However, using the right types of storage helps ensure that your items are properly preserved.

Plastic bins might be suitable for tools and Christmas decorations, but they are not the ideal long-term storage solution for everything.

Consider this the little nudge you needed to get started on the organising you've been putting off.

Here are seven things you should NOT be storing in plastic containers:

1. Photos

This might seem like a serious throwback, but many people still have physical photographs, and film photography is also trendy in 2025.

Unfortunately, storing them in plastic containers could destroy them. Heat and moisture could cause them to fade or warp, losing their quality.

Experts suggest using paper boxes and acid-free archival sleeves, keeping them away from glue or other adhesives, and having a digital backup, just in case.

2. Electronics

Choosing to store your electronics in plastic containers might be the riskiest of all.

Excess moisture can lead to short circuits and fried appliances or gadgets.

It is highly recommended that electronics be stored in a breathable tote or their original packaging. 

Another top tip is using silica gel packets. Placing one in the box or bag can lower the risk of moisture exposure. Keep your tech in a temperature-controlled room, such as the bedroom, instead of the attic or garage.

3. Leather

If you notice that your leather items have begun to crack, they have been in storage for too long. As mentioned before, excess moisture loves to creep into plastic bins and can lead to leather cracking.

The moisture could also cause mildew or mould, as plastic is not breathable and stifles leather material over time.

Store leather items in dust bags, and depending on the size of the item, wrap it in tissue paper, newspaper or a cotton blanket.

4. Documents

Birth certificates, bills and other essential documents are not things you want being destroyed. And it can be hard to replace.

Ideally, documents should be stored in a filing cabinet or safe. Plastic containers are not fireproof or a good barrier during a natural disaster.

The moisture it traps can cause documents to fade, deteriorate and grow mould. Lockboxes and fireproof storage are recommended instead.

5. Books and Physical Media

Whether you're storing books, CDs, video games or DVDs, plastic bins can cause these items to warp, fade and rot.

Store these items away from sunlight in cardboard boxes or canvas bags to avoid moisture and sun damage.

You are also advised to keep them in rooms where temperature and humidity can be closely monitored.

6. Food

Storing your leftovers in a plastic container for a night or two isn't the end of the world. However, for long-term food storage, use BPA-free silicone or glass containers.

Food with fish, lots of garlic and onions can risk odours being absorbed into the plastic.

This could also be a risk for pet food. It is best to store pet food in a food-safe metal storage bin instead. You can use a plastic container if the food remains in its original packaging.

7. Delicate Fabrics

These containers often trap excess moisture and heat, leading to the fabric losing its integrity over time.

Some materials, such as lace, silk, cashmere and wool, are more sensitive than others.

When stored incorrectly, these materials can become musty, resulting in that stinky smell we've all experienced.

Instead, use vacuum-sealed bags or knitted totes for clothing, bedding and other fabrics.
