Research from the National Employment Savings Trust (Nest) has even suggested we have spent a collective £6.2 billion on unused items in the last five years.
The survey of 2,000 Britons found the average person has spent £129 on unused goods, with the nation forking out £1.2 billion each year on rarely or never used items.
That means our homes may very well be hosting a little treasure trove that can help boost our savings pots for future use.
Indeed, the Nest study discovered that the average amount cash-savvy Britons made by selling their unwanted goods was £25.
And for one in ten respondents, they made more than £100 selling their unused items, so it is well worth the effort of a spring clean.
"We've all bought things that just end up gathering dust at the back of the cupboard," commented Graham Vidler, director of communications and engagement at Nest.
"It's easy to feel guilty about wasting money when you don't end up using what you've paid for, but your unused goods could turn out to be hidden treasure if you sell them on to someone who needs them."
So what kind of goods could be sold off for a handful of savings? Well, according to the Nest study, nearly half of respondents invested in expensive kitchen appliances that went unused.
In fact, 17 per cent of people dug deep for a blender, which has an average retail price of almost £130, so there are obvious savings to be made.
And the spring clean does not just have to be about objects, as the research found 36 per cent of respondents paid for a gym membership they did not use, which has an annual cost of around £442.
So when thinking about spring cleaning for saving, consider the benefits of de-cluttering unused direct debits as well as household goods.
