When you choose to pack your items in a storage unit, usually it’s because you don’t want to sell them or throw them away. Your valuables and other items mean something to you, so you want to make sure they will be in the same condition you packed them in when you come back to the unit. It’s heartbreaking to open up those boxes or visit storage after a while and find your things have deteriorated. In our how to prevent mould in self-storage units guide, we give you tips on storing items appropriately and how to clean mould if you do find it.

Packing items properly for storage units

Mould prevention is a crucial consideration when storing furniture and other items in a self-storage unit. The best way to make sure your goods stay in the best shape is to pack everything properly and prepare it for storage correctly. To prevent mould on items in storage units, you will need to:

Ensure items are dry

Everything you place in storage needs to be thoroughly dry. One damp item can attract mould, and the issue can spread across the rest of the unit. Before packing things in boxes or other containers, make sure everything is completely dry. Check each item and give everything plenty of time after cleaning before placing it in a box.

There are certain things that you should never store in self-storage units. Oil, chemical cleaners, aerosol sprays are just a few of them. Read our previous article about what not to store in storage units to find the whole list of not recommended items.

Storage materials

One essential part of long-term storage is using suitable materials for storing your possessions. Plastic bags or old boxes are not the best options. Use storage boxes, clothing bags, and bubble wrap to ensure the best conditions for your items. Another way to protect items from moisture is to include moisture-absorbing packages within the packing materials.

Storage unit 

Where your store your items is just as important as how you store them. Choosing the best storage unit and packing the unit properly is the best way to ensure your things stay in the best condition. Use mould prevention products on the surfaces you are placing in the unit, and make sure you allow airflow around the boxes by not packing the unit too tightly. If the storage unit has a concrete floor, place items on shelves, or elevate boxes by placing them on pallets.

How to clean mould off items in a storage unit

When looking at how to prevent mould, the best way is to check your storage unit regularly. If you do unfortunately find mould, you should clean the affected area as quickly as possible. 

The best way to prevent mould from spreading to other items is to either remove the affected pieces from the storage unit or remove the mould completely before storing them again. 

Cleaning mould with vinegar is possible by combining 1 part vinegar and one part water and applying it to surfaces. If you want to clean black mould off the walls of items in your unit, you can use a bleach solution of one part bleach and three parts water.
